This document discusses neuroinflammation and its relationship to chronic pain and depression. It begins by outlining the common neurobiology of these conditions, including involvement of the hypothalamic-pituitary-adrenal axis, inflammatory cytokines, neurotransmitters, and glial cells like microglia and astrocytes. It then discusses the role of the gut-brain axis and gut microbiome in neuroinflammation. The document proposes that chronic pain and depression are actually symptoms of underlying neuroinflammation in the brain. It concludes by outlining a 3-phase treatment approach focused on eliminating triggers of neuroinflammation, treating the underlying issue, and reducing mast cell and microglial activation.
This document provides an overview of multiple sclerosis (MS) models and the challenges of translating findings from animal models to clinical applications. It discusses key aspects of MS like pathogenesis, clinical courses, and neurodegeneration. Common MS models like experimental autoimmune encephalomyelitis (EAE) are described along with their limitations in mimicking the human disease. Issues like preclinical failure to translate findings and limitations of experimental design that can contribute to clinical trial failures are reviewed. Guidelines for improving experimental design and reporting are also mentioned.
Anti-NMDA receptor encephalitis is characterized by psychiatric symptoms, seizures, memory deficits, and autonomic dysfunction. It is caused by autoantibodies against the NMDA receptor. Diagnosis involves detecting antibodies in CSF or blood. Treatment includes immunotherapy like steroids, IVIg, or plasma exchange. With prompt treatment, around 75% of patients recover or have mild deficits, but delayed treatment leads to worse outcomes.
This document summarizes an epigenetic study aiming to reveal the etiology of schizophrenia. It discusses that environmental factors can lead to epigenetic changes like DNA methylation and histone modification in genes related to GABA and reelin, which are downregulated in schizophrenia. Studies have found differences in histone modifications and enzymes like HDAC1 in schizophrenic brains. Epigenetic modifications from factors like prenatal nutrition, drug use, and stress may contribute to schizophrenia risk and symptoms. Understanding these epigenetic mechanisms could help discover new treatments and prevention strategies for schizophrenia.

Immunomudulators in multiple_sclerosisSantosh Dash
The document summarizes immunomodulation in multiple sclerosis. It discusses the history and evolution of immunomodulatory therapies for MS including corticosteroids, interferons like IFN β-1a, IFN β-1b, glatiramer acetate, mitoxantrone, natalizumab, alemtuzumab, and oral medications like fingolimod. It covers their mechanisms of action, indications, dosages, evidence from clinical trials, side effects and contraindications. The goal of these disease-modifying therapies is to reduce relapses, disability progression, and new inflammatory lesions in the brain.
Multiple sclerosis is an immune-mediated disease where the body's immune system attacks the protective myelin sheath surrounding nerves in the central nervous system. This results in scar tissue and damage to oligodendrocytes, disrupting nerve signals. The exact cause is unknown but is thought to involve both genetic and environmental factors. There are several types of MS including clinically isolated syndrome, relapsing-remitting MS, primary progressive MS, and secondary progressive MS. While not caused by a single gene, several genes have been associated with MS risk including HLA-DRB1, CYP27B1, IL2RA, and IL7R. Diagnosis involves MRI imaging, evoked potential tests, and examinations of
This document provides a publication list for Jes Dietrich, including 57 publications from 2015 to 1998. The publications cover a range of topics related to tuberculosis vaccines and immune responses to Mycobacterium tuberculosis. Key findings include identifying protective vaccine antigens against Streptococcus pyogenes, differential immune responses to nutrient-starved M. tuberculosis, and evaluating adjuvant and vaccine strategies to boost BCG-primed immunity against tuberculosis.

Michael hutchinson - Natalizumab therapy for MS - 2009ipposi
Natalizumab is a monoclonal antibody approved for the treatment of relapsing-remitting multiple sclerosis. It works by blocking the alpha-4 integrin and preventing immune cells from migrating across the blood-brain barrier. Clinical trials showed it significantly reduced relapse rates and disability progression compared to placebo. However, it carries a risk of progressive multifocal leukoencephalopathy due to reactivation of the JC virus in some patients, especially after over 24 infusions. Careful monitoring is required for patients receiving natalizumab therapy.
Caffeine, Through Adenosine A3 Receptor-Mediated Actions, Suppresses Amyloid-...Mahmoud Lotfy Soliman
1. Caffeine prevents the internalization of LDL cholesterol in neurons by blocking adenosine A3 receptors (A3Rs). Caffeine decreased neuronal internalization of DiI-labeled LDL cholesterol in a concentration-dependent manner.
2. Blocking A3Rs with a specific antagonist or knocking down A3Rs with siRNA mimicked caffeine's effects in decreasing LDL cholesterol internalization, while activating A3Rs increased internalization.
3. By blocking A3R-mediated internalization of LDL cholesterol, caffeine decreases amyloid beta (Aβ) generation from amyloid precursor protein (APP), which is increased by LDL cholesterol internalization through enhanced amyloidogenic processing of APP in endosomes.
Guillain-Barré syndrome is an acute autoimmune disorder that causes inflammation of the peripheral nerves. It most commonly develops one to three weeks after a respiratory or gastrointestinal infection. Clinical features include rapidly progressive ascending paralysis, loss of deep tendon reflexes, and possible involvement of cranial nerves or the autonomic nervous system. Diagnosis is based on the clinical features and examination findings. Treatment involves intravenous immunoglobulin or plasma exchange to stop progression. Most patients recover fully but it may take several months and some are left with residual deficits.
Multiple Chemical Sensitivity (MCS) and Electromagnetic Hypersensitivity (EHS...Crimsonpublisherscojnh
Multiple chemical sensitivity (MCS) and electromagnetic hypersensitivity are disabling conditions hallmarked by adverse reactions to chemicals and electromagnetic frequencies at levels generally considered safe. MCS is underpinned by a vicious cycle of escalating sensitivity initiated by exposure to seven classes of neurotoxicants. Our case study concerns a family sensitized to foods, chemicals and electromagnetic radiation after heavy exposure to phenoxy herbicides and organophosphate pesticides. Also addressed are a number of conditions frequently co-morbid with MCS, which also frequently involve an environmental sensitivity component-which include migraine, rheumatoid arthritis, irritable bowel syndrome, ADHD, hypertension and certain cardiac problems.
Multiple chemical sensitivity (MCS) and electromagnetic hypersensitivity (EHS) are disabling medical conditions with ramifications for not only affected individuals and their families but for wider society as well. Sensitised individuals react adversely to everyday chemicals and/or electromagnetic frequencies at levels customarily considered innocuous; indeed, their reactive threshold may be orders of magnitude below the norm. In one instance the difference in electromagnetic sensitivity was estimated at 1010 [15]. This woman also reacted to minute traces of lemon oils picked up by a family member; he had merely been in a room with a bowl of lemons, yet hyperosmia-a hallmark of MCS-allowed her to detect their presence, and hypersensitivity to react to it

Social stress induces neurovascular pathology_Masuma_AkterMasuma Sani
Chronic social stress alters blood-brain barrier (BBB) integrity through downregulation of the tight junction protein claudin-5. This drives the development of depression-like behaviors. Specifically, chronic social defeat stress reduces claudin-5 mRNA and protein levels in the nucleus accumbens, causing ultrastructural abnormalities in blood vessels and increased BBB permeability. Antidepressant treatment can reverse these effects by normalizing claudin-5 expression. Knockdown of claudin-5 also produces depression-like behaviors in stressed mice, confirming its role in mediating stress responses.
This document provides a mini review of autoimmune encephalitis. It begins by introducing autoimmune encephalitis as an inflammatory central nervous system disorder that was previously underrecognized. Autoimmune encephalitis is believed to be the third leading cause of encephalitis. The review discusses the clinical presentations of autoimmune encephalitis and how it can affect the gray matter of the brain. It describes the different classifications of autoimmune encephalitis based on whether it is paraneoplastic or non-paraneoplastic, and based on the targets of antibodies in the body. Specific types of autoimmune encephalitis are discussed like anti-NMDA receptor antibody limbic encephalitis. The review concludes that autoimmune en
Tryptophan metabolism and the kynurenine pathway play an important role in neuropsychiatric disorders and immune regulation. Tryptophan is converted to kynurenine via the enzymes IDO and TDO, with kynurenine then processed differently by astrocytes and microglia in the brain. Pro-inflammatory cytokines increase IDO/TDO activity, depleting tryptophan and producing neurotoxic metabolites, while anti-inflammatory cytokines decrease their activity. Abnormalities in this pathway have been linked to depression, psychosis, Alzheimer's, and autoimmune diseases. IDO also plays a key role in immune tolerance by inhibiting T-cell responses and preventing rejection of the fetus during
Chronic acquired demyelinating polyneuropathy (CADP) variants include chronic inflammatory demyelinating polyneuropathy (CIDP), multifocal motor neuropathy (MMN), multifocal acquired demyelinating sensory and motor neuropathy (MADSAM), and distal acquired demyelinating symmetric neuropathy (DADS). Each condition has unique clinical features, electrodiagnostic tests, and responses to treatment that help distinguish them as part of the heterogeneous group of immune-mediated demyelinating disorders of the peripheral nervous system.
This document discusses a study on the effects of transcranial magnetic stimulation (TMS) therapy for depression. Key points:
- TMS was found to effectively relieve symptoms of depression without common side effects of insomnia seen with antidepressants.
- TMS targets the prefrontal cortex to influence brain activity and mood regulation. It does not contribute to sleep problems.
- A separate study found supplying the chemical D-serine improved brain plasticity and memory function in depressed rats by supporting astrocyte cells. Advances may lead to new depression treatments.

Vagal Nerve stimulation
Vagus nerve stimulation (VNS) is a medical treatment that involves delivering electrical impulses to the vagus nerve. It is used as an add-on treatment for certain types of intractable epilepsy and treatment-resistant depression. Frequent side effects include coughing and shortness of breath. Serious side effects may include trouble talking and cardiac arrest.
This document provides an overview of immunoglobulin E (IgE) and IgE receptors. It discusses the history and discovery of IgE, the structure and function of IgE, and IgE receptors such as FcεRI and CD23. It also covers the clinical significance of IgE levels in various diseases, including allergic diseases, infections, and non-atopic diseases. IgE plays an important role in type I hypersensitivity reactions and defense against parasites. The production and role of IgE is highly complex and involves interactions between immune cells, cytokines, and environmental exposures.
The document summarizes myasthenia gravis (MG), an autoimmune disorder causing muscle weakness. MG results from antibodies blocking acetylcholine receptors at the neuromuscular junction, inhibiting nerve signal transmission. Signs and symptoms include weakness of eye, facial, swallowing, and respiratory muscles. Diagnosis involves testing for acetylcholine receptor antibodies. Treatment includes anticholinesterases, immunosuppressants, plasmapheresis, IV immunoglobulins, and sometimes thymectomy. While the immune system's role is clear, further research is still needed to develop more effective medical treatments without adverse effects.
74th ICREA Colloquium "Autoimmunity meets neurodegeneration: different pathwa...ICREA
Studies during the last 10 years have revealed a new category of brain diseases in which crucial neuronal receptors are attacked by autoantibodies. As a result of this attack there is a reduction of the target synaptic proteins leading to alterations in synaptic transmission. The clinical manifestations vary according to the receptor involved, and may resemble many of the symptoms caused by neurodegenerative diseases in which specific receptors are involved, including among others Parkinson, epilepsy, chronically progressive sleep disease, or schizophrenia.
This document discusses autoimmune encephalitis, which occurs due to antibodies against neuronal cell proteins or synaptic receptors. It can comprise 5-10% of encephalitis cases. The most common type is anti-NMDAR encephalitis, which targets the NMDA receptor. It most often affects females under 18 and follows a predictable clinical course with psychiatric, neurological, and decreased consciousness symptoms. Diagnosis involves identifying antibodies in CSF or serum and MRI/EEG may show nonspecific abnormalities. Treatment involves immunotherapy like steroids, IVIG, plasma exchange, and rituximab. Outcomes range from full recovery to relapse or residual deficits.
This document defines multiple sclerosis and discusses its pathophysiology, risk factors, classification, clinical features, investigations, and management. Multiple sclerosis is an inflammatory disease that damages the myelin sheaths around nerve axons in the brain and spinal cord, leading to demyelination and scarring. It typically affects young adults and is more common in females. While the cause is unknown, it may involve genetic and environmental factors. MRI is the most accurate test for diagnosis, showing lesions in the white matter. Treatment aims to reduce relapses using disease-modifying drugs like interferons or glatiramer acetate.
The document discusses various hypotheses for the pathogenesis of paraneoplastic syndromes. It is now accepted that paraneoplastic syndromes are immune-mediated disorders triggered when a tumor expresses neural antigens, leading the immune system to attack both the cancer and nervous system. However, questions remain regarding the specific immune mechanisms and why some tumors are destroyed while others persist and prove lethal.

Different GBS subtypes are associated with different antiganglioside antibodies and clinical courses.
Multiple sclerosis and newer concept in management till 2014 maydrnikhilver
This document provides information about Multiple Sclerosis (MS), including what it is, possible causes, types, diagnosis, treatment and newer concepts in management. It defines MS as a chronic neurological disorder affecting the central nervous system, where myelin is destroyed in the brain and spinal cord. The exact cause is unknown but is believed to involve immunological, viral, environmental and genetic factors. Diagnosis involves clinical symptoms and tests like MRI, CSF examination and evoked potentials. Treatment includes managing acute attacks, reducing disease activity through medications, and symptom management. Newer oral medications and concepts in disease-modifying therapies are discussed.
This document discusses neuroinflammation and its role in various neurological diseases. It begins by defining neuroinflammation as inflammation of the nervous system, which can be triggered by infection, injury, or autoimmunity. Neuroinflammation is characterized by activation of glial cells like microglia and astrocytes. The document then examines the causes and types of neuroinflammation, roles of cytokines and growth factors, and how neuroinflammation contributes to the progression of diseases like Parkinson's and multiple sclerosis. Specifically, it is proposed that neuroinflammation plays an important role in the toxicity and progression of these diseases. Future therapeutic strategies aim to reduce neuroinflammation through inhibiting inflammatory cytokines or using anti-inflammatory drugs.
Chronic stress can lead to depression through several pathways in the body and brain. The stress response involves the hypothalamic-pituitary-adrenal axis and sympathetic nervous system, which elevate cortisol and catecholamine levels. Over time, prolonged activation of these systems due to stress can result in allostatic load, damaging the body and brain through effects on inflammatory and immune responses. This dysregulation of stress mediators is associated with increased risk of depression as well as medical conditions like heart disease and metabolic syndrome. Meditation may help reduce stress's harmful impacts through effects on the brain's opioid and stress response systems.
The document discusses prion diseases, which are neurodegenerative disorders caused by abnormal prion proteins. It covers the discovery of prions, the different forms of human and animal prion diseases, and the molecular pathogenesis involving the conversion of normal prion protein (PrPc) to abnormal disease-causing prion protein (PrPsc). Clinical features of various human prion diseases like CJD are described. Diagnosis involves neuroimaging, EEG, CSF analysis and detection of PrPsc in brain tissue. Histopathology shows vacuolation, gliosis and prion plaques. Variant CJD results from eating meat from cows with BSE.

This document provides information on laboratory diagnosis and workup for patients suspected of having autoimmune encephalitis. It discusses several key points:
- Autoimmune encephalitis is characterized by neurological symptoms caused by autoantibodies against neuronal surface or synaptic proteins.
- When evaluating a patient, tests should aim to confirm the diagnosis through detection of autoantibodies in blood or CSF, exclude other causes through CSF and imaging studies, and identify any clinical features associated with specific autoantibodies.
- The two main assays used are tissue-based assays for initial screening and cell-based assays for confirmation. EEG may show non-specific slowing or epileptiform activity. Continuous EEG monitoring can help detect non
Fibromyalgia is a disorder characterized by widespread musculoskeletal pain accompanied by fatigue, sleep issues, and mood problems. Researchers believe fibromyalgia amplifies pain signals by affecting how the brain processes pain. Symptoms sometimes begin after physical trauma, surgery or stress. While there is no cure, medications and exercise can help control symptoms. Women are more likely to be affected, and fibromyalgia is often accompanied by headaches, digestive issues, anxiety or depression.

The document discusses the relationship between the immune system and brain conditions from a toxicological perspective. It summarizes several studies that found:
1) The immune system plays an important role in brain development and any immune activation during development can affect later neural function, immune function, mood and cognition.
2) A drug called fingolimod that modulates sphingosine-1-phosphate receptors, reducing lymphocyte migration from lymph nodes, significantly reduced relapse rates and disability progression in multiple sclerosis patients compared to placebo.
3) Systemic immune status can influence local brain tissue conditions, and this effect could be considered a type of toxicological effect worth further investigation to better understand disease pathogenesis and develop new pharmacological
This document discusses three neurological conditions: Guillain Barre Syndrome, Multiple Sclerosis, and Myasthenia Gravis.
Guillain Barre Syndrome is a condition causing rapid demyelination of peripheral nerves resulting in ascending weakness. It can be caused by infections or injuries and leads to impaired nerve signaling. Clinical features include muscle weakness and diminished reflexes.
Multiple Sclerosis is an immune-mediated disease causing destruction of the myelin sheath in the central nervous system. It has autoimmune and genetic risk factors and results in plaques forming on the myelin sheath, interrupting nerve signals. Common symptoms are fatigue, weakness, numbness, and lack of coordination.

This study examined the effects of perforin, a pore-forming protein, on oligodendrocytes cultured from SJL mice. Oligodendrocytes were exposed to perforin for up to 2.5 hours and examined using microscopy. The results showed that the majority of oligodendrocytes were killed within 60-90 minutes via pore expansion and membrane disruption. Structural features included cell body swelling, fenestration and fragmentation of membranes and processes, cytoplasmic vacuolation, and breakdown of the nuclear envelope. These patterns of damage resembled those seen in multiple sclerosis lesions. The findings suggest that perforin may play an important role in demyelination in multiple sclerosis.
Paraneoplastic syndrome (PNS) is the term used to refer to the disorders that accompany the benign or the malignant tumors and are not caused by mass effect or invasion / metastasis.
These disorders are triggered by an immune system response to neuronal proteins expressed by the tumor(onconeural proteins).
These PNS also occur due to substances secreted by the neoplasm itself.
CORONOFOBIA - Passos práticos para equilibrar as defesas do corpo e da menteLouis Cady, MD
Esta palestra, apresentada em 29 de maio de 2021 para o Congresso de Medicina Integrativa para a Saúde Mental 2020, promovido pelo Laboratório Great Plains no Brasil, enfocou coisas simples e de bom senso que os pacientes (e seus médicos) podem fazer para se manter seguros e viver durante o Pandemia do covid.
Os seguintes conceitos holísticos foram revisados:
- sono adequado e por que é tão importante;
- o uso de melatonina, cientificamente validada como tendo atividade antiviral (referências citadas);
- a importância de diminuir o estresse e técnicas para fazê-lo;
- a necessidade de "comer frutas e vegetais" como sua mãe e sua avó ensinaram devido à ingestão de carotenóides e antioxidantes ((referências citadas);
- o uso adequado de suplementos vitamínicos / nutricionais (referências citadas).
O foco desta apresentação não foram medidas heróicas para salvar vidas na unidade de terapia intensiva para pacientes gravemente enfermos com COVID, mas, sim, técnicas de bom senso, práticas, baratas e (em alguns casos) GRATUITAS para melhorar você e seus pacientes 'saúde e resistência às doenças.
This document provides an overview of strategies for pursuing successful mold litigation cases. It recommends only taking cases that have clear indicative symptoms, opportunities to collect positive mold sample tests, and treating physicians willing to testify. The first steps include taking detailed client statements and securing expert testimony from specialists like microbiologists and industrial hygienists. Well-drafted complaints and early expert designation are emphasized. Motions to dismiss and for summary judgment can be defeated by complaints stating the legal claims and elements. Overall, the document outlines best practices for case evaluation, evidence collection, complaint drafting, discovery, motions, and trial strategies in mold litigation.
This document discusses the health effects of mold and mycotoxin exposure. It notes that mold can cause toxic and inflammatory effects through the release of mycotoxins and other compounds. Common sources of mold exposure are water-damaged buildings and contaminated food. Mycotoxins have been shown to impact the brain, liver, kidneys and other organs. They may worsen conditions like Lyme disease, cognitive issues, and immune dysfunction. Specific mycotoxins like ochratoxin and aflatoxins are carcinogenic and neurotoxic. Testing food supplies found frequent mycotoxin contamination globally. Strict reporting of contaminated food samples is required.
This document discusses clinical and consumer applications of microarrays and genotyping technologies. It provides an overview of genotyping and different technologies like PCR microarrays and SNP microarrays. It describes how microarrays are still useful despite the rise of sequencing due to their low cost, high throughput, and ability to test millions of markers. The document outlines several applications of microarrays like direct-to-consumer testing, pharmacogenetics, and clinical sequencing. It also discusses challenges and trends in these areas like global initiatives to increase genomic data sharing.
This document discusses neuroinflammation and its relationship to chronic pain and depression. It begins by outlining the common neurobiology of these conditions, including involvement of the hypothalamic-pituitary-adrenal axis, inflammatory cytokines, neurotransmitters, and glial cells like microglia and astrocytes. It then discusses the role of the gut-brain axis and gut microbiome in neuroinflammation. The document proposes a new model where chronic pain and depression are caused by neuroinflammation in the brain, rather than the traditional view of neuroinflammation being caused by these conditions. It concludes by outlining a 3-phase treatment approach focused on eliminating triggers of neuroinflammation, treating the underlying issue, and
The document discusses recovering the immune system through exposure to dirt and microbes. It describes how a chronic cell danger response can lead to chronic disease when the response is not reversed. Exposure to diverse microbes, parasites, nature, exercise, fasting and nutrient-dense foods can help build resilience against stressors and recover from a chronic cell danger response through hormesis. Spending time in nature, being exposed to soil organisms, and incorporating herbal remedies can also support immune function and resilience.
This document summarizes a presentation on the evaluation and treatment of mold toxicity using mycotoxin assays. It discusses evaluating patients for mold toxicity based on their symptoms and biomarkers, as mold toxicity can mimic many other conditions. Treatment involves removing mold toxins from the body, eliminating mold exposure, and repairing the damage caused by toxins, as outlined in Dr. Shoemaker's biotoxin pathway model. Genetic testing for HLA-DR is also discussed as valuable to diagnosis.
This document discusses mold and mycotoxins. It describes how mold exposure can cause toxicity and affect the brain, liver, kidneys and other organs. Several types of mold produce toxic mycotoxins like aflatoxins, ochratoxin A, and trichothecenes. Prolonged exposure to indoor molds or mycotoxins in food has been linked to decreased cognitive function in children as well as mental health issues in adults. Testing methods are discussed to evaluate patients for toxic encephalopathy resulting from mold and mycotoxin exposure.
8 Surprising Reasons To Meditate 40 Minutes A Day That Can Change Your Life.pptxHolistified Wellness
We’re talking about Vedic Meditation, a form of meditation that has been around for at least 5,000 years. Back then, the people who lived in the Indus Valley, now known as India and Pakistan, practised meditation as a fundamental part of daily life. This knowledge that has given us yoga and Ayurveda, was known as Veda, hence the name Vedic. And though there are some written records, the practice has been passed down verbally from generation to generation.
Cell Therapy Expansion and Challenges in Autoimmune DiseaseHealth Advances
There is increasing confidence that cell therapies will soon play a role in the treatment of autoimmune disorders, but the extent of this impact remains to be seen. Early readouts on autologous CAR-Ts in lupus are encouraging, but manufacturing and cost limitations are likely to restrict access to highly refractory patients. Allogeneic CAR-Ts have the potential to broaden access to earlier lines of treatment due to their inherent cost benefits, however they will need to demonstrate comparable or improved efficacy to established modalities.
In addition to infrastructure and capacity constraints, CAR-Ts face a very different risk-benefit dynamic in autoimmune compared to oncology, highlighting the need for tolerable therapies with low adverse event risk. CAR-NK and Treg-based therapies are also being developed in certain autoimmune disorders and may demonstrate favorable safety profiles. Several novel non-cell therapies such as bispecific antibodies, nanobodies, and RNAi drugs, may also offer future alternative competitive solutions with variable value propositions.
Widespread adoption of cell therapies will not only require strong efficacy and safety data, but also adapted pricing and access strategies. At oncology-based price points, CAR-Ts are unlikely to achieve broad market access in autoimmune disorders, with eligible patient populations that are potentially orders of magnitude greater than the number of currently addressable cancer patients. Developers have made strides towards reducing cell therapy COGS while improving manufacturing efficiency, but payors will inevitably restrict access until more sustainable pricing is achieved.
Despite these headwinds, industry leaders and investors remain confident that cell therapies are poised to address significant unmet need in patients suffering from autoimmune disorders. However, the extent of this impact on the treatment landscape remains to be seen, as the industry rapidly approaches an inflection point.

59. Definition of Mycotoxins
Secondary metabolites of fungi belonging to Aspergillus, Penicillium, Stachybotrys and Fusarium
Found in water-damaged homes and buildings, especially Penicillium expansum, Aspergillus
fumigatus and Aspergillus versicolor species
Common contaminants of human foodstuffs: wine, coffee beans, nuts and animal feed
Can enter the food chain through contaminated cereals and foodstuffs such as: milk, meat and
eggs, obtained from animals fed mycotoxin-contaminated feedstuffs
Ingestion of low levels of toxins overtime, may cause an array of metabolic, physiologic and
immunologic disturbances
118, 119, 120,127
60. Classification of Mycotoxins
• Mycotoxins are challenging to classify, due to their diverse chemical structures and
biosynthetic origins. Thus, they can be classified as:
Hepatotoxins
Nephrotoxins
Neurotoxins
Immunotoxins
Teratogens
Mutagens,
Carcinogens
Allergens…
119, 121
61. Mycotoxin Transmission Health Impact
Aflatoxins: B1, B2, G1, G2, M1, M2 • Peanuts and peanut products, corn, wheat,
rice, cottonseed, nuts, eggs, dairy products,
figs
• Water-damaged buildings
Hepatotoxicity, bile duct hyperplasia, hemorrhage of intestinal tract and
kidneys, carcinogenesis (liver tumors), immunotoxin, mutagenic, neurotoxic.
Ochratoxins A • Cereal grains (wheat, barley, oats, corn), dry
beans, moldy peanuts, cheese, coffee,
raisins, grapes, dried fruits, wine
• Water-damaged buildings
Nephrotoxic, liver damage, teratogenesis, kidney tumors, neurotoxic,
immunotoxin, class 2B possible human carcinogen
Trichothecenes (T-2, Deoxynivalenol,
diacetoxyscirpenol (DON),Satratoxin)
• Corn, wheat
• Water-damaged buildings
• Biologic warfare
Neurotoxins, Immunotoxin, Digestive disorders, oral lesions, hemorrhage of
stomach, heart, intestines, lungs, bladder, kidney, edema
Gliotoxin • Water-damaged buildings
• GI Tract infections
Immunotoxin, cytotoxic, genotoxic, apoptotic cell death inducer
Patulin Apples, apple juice, wheat, moldy feed Brain and lung edema, lung hemorrhage, paralysis of motor nerves,
convulsions, carcinogenesis
Zearalenone Corn, hay Estrogenic effects (edema of vulva, uterine enlargement), testicular atrophy,
enlargement o mammary glands, abortion
119, 121, 127, 128
62. Routes of Exposure
Human exposure to mycotoxins can occur through different routes:
Gastrointestinal: through ingestion of contaminated food, beverages and water
Respiratory: inhalation of aerosolized particles
Mucous
Cutaneous
119, 120, 121
63. Routes of Exposure
Experiments studying effects of acute inhalation of T2 mycotoxins in both young and mature mice
showed that inhalation of T2 mycotoxins is:
• At least 10 times more toxic than systemic administrations
• At least 20 times more toxic than dermal administration
120
64. Aflatoxin B1 in the Brain
Brain autopsies of children living in areas with high aflatoxin exposure revealed its presence in
81% of the cases studied
At low doses, Aflatoxin B1 compromises the integrity of the blood brain barrier, studies suggest
that lipophilic nature of aflatoxins allow their storage in the brain tissue.
Oxidative metabolism of AFB1 is active even at very low doses of exposure in neutrophils,
dendritic cells, lymphocytes and monocytes. This may be due to an isoform of cytochrome 450
(CYP1A1)
124, 130
65. Aflatoxins and Microglia
• In murine CNS-derived cells, AFB1 treatment caused microglia to express proinflammatory genes especially TLR2,
MyD88, Ikβ, TNF-α, CXCR4 and iNOS at early hours of exposure
• Overexpression of iNOS mRNA remained high even after 48 hours of exposure
• AFB1 exposure triggers the overexpression of TLR2 with the activation of NF-kB pathway, leading to an increase in
secretion of TNFα in microglial cells.
• The secretion of IL-1β could be an indicator of an inflammatory condition in both astrocytes and microglia
• Up-regulation of iNOS mRNA gene could be an indicator of ongoing oxidative stress on both cell types
• Over-expression of p53 gene in microglia indicates the activation of pro-apoptotic pathways and cytotoxic activity of
low dose AFB1 in these cells
130
66. Aflatoxins and Astrocytes
Treatment of astrocytes with AFB1 induced higher secretion of IL-1, IL-6,
TNFα, and IL-10
Simultaneously, AFB1 exposure triggers the overexpression of pro-apoptotic
genes in astrocytes (p21, p53), and genes related to apoptosis occurrence
(caspace 3 and 8)
130
68. Ochratoxin A in the Brain
OTA compromises the cytoskeletal integrity of astrocytes
OTA affect gene expression pertaining to the brain inflammatory response system
OTA decreses the neuroprotective capacity of glial cells
OTA causes acute depletion of striatal dopamine
Increased oxidative stress triggers high lipid peroxidation and oxidative DNA damage
Inhibition od oxidative DNA repair activity
Evidence of apoptosis in the substantia nigra, striatum and hippocampus and other brain
regions
These brain regions, especially the hippocampus are primary sites for neurodegeneration
123
69. Trichothecenes: T2 Toxin in the Brain
Low levels of T2 toxin are responsible for the changes in the metabolism of brain
biogenic amines, leading to changes in the amino acid permeability across the
BBB
T2 is easily distributed to the fetal and adult brain inducing apoptosis in the CNS
125
70. Lymphocytes show maximum sensitivity to T-2 toxins, Macrophages and B
cells are also targets
T-2 has immunomodulatory and immunosuppressive activity in the immune
system
Oral, parenteral and cutaneous exposure produces lesions in hematopoietic,
lymphoid and gastrointestinal tissues and functional suppression of
reproductive organs
Trichothecenes: T-2 Toxin
121, 124
71. Gliotoxins
Aspergillus fumigatus is frequently found in moldy houses, especially from dust produces
gliotoxin and other toxins.
Candida Albicans is another source of gliotoxins
Gliotoxin is known to possess a number of cytotoxic and immunosuppressive activities
such as:
Inhibition of superoxide release, migration and microbicidal activity
Cytokine release by leukocytes
T-lymphocyte mediated cytotoxicity and genotoxicity
Inducer of apoptotic cell death in different cell types
126, 129
72. Code Test Specimen Value Result Not Present if less than Equivocal if between Present if greater or

73. Fumonisin B1 (FB1)
May be responsible for disruption of sphingolipid metabolism inducing lipid
peroxidation, which may affect DNA integrity leading to DNA oxidized bases,
altering cell membrane and causing cytotoxicity
119, 123
74. Fumonisin B1 (FB1) in the Brain
FB1 toxicity is implicated in the etiology of neuronal tubule defects in children
Reports indicate a potential for direct neurotoxicity
FB1 induces oxidative stress in human, rat and mouse neural cell cultures
Inhibits axonal growth in cultured hippocampal neurons
Disrupts myelination in glial cells
Causes changes in neurotransmitter metabolite levels in different brain regions
119, 123
75. Neurocognitive Symptoms
Measured IQ scores in children exposed to indoor mold for more than 2 years showed
statistically significant IQ deficits of approximately 10 points using the WISC-R scale of
intelligence.
• Longer exposure tripled the risk of low IQ scores
• Depression in increased in people exposed to damp indoor environments
• Patients present with other classic neurologic disorders including:
1. Pain syndromes
2. Movement disorders
3. Delirium
4. Dementia
5. Disorders of balance and coordination
120, 122
76. Mycotoxins and Depression
Patients with mold exposure history report moderate to severe levels of cognitive,
physical and emotional symptoms, mainly Depression
Electroencephalography results showed hypoactivation in the frontal cortex
Neuropsychological testing indicated impairments similar to those seen in mild
traumatic brain injury
Studies demonstrated presence of OTA, AF M1, FB1 in urine and serum of children
diagnosed with Autism compared to healthy
120, 122
77. Mycotoxins and the gastrointestinal
tract
Gut microbiota impacts the permeability of the intestines thus the absorption
and bioavailability of mycotoxins
Mycotoxins can disrupt the gut microbiome
Mycotoxins have direct toxicity of the intestinal barrier
Mycotoxins can impair the local immune response in the intestines
Gut microbiota can detoxify mycotoxins
119
78. Mycotoxin Interaction in Hepatic
and Intestinal Epithelial Cells
119
“Tissues with high rates of cell turnover, are very susceptible to mycotoxins, due
to their ability to strongly compromise the homeostasis of self-renewing
capacities of cells causing the impairment of epithelial barrier increasing
membrane permeability”
79. Mycotoxin Interaction in Hepatic
and Intestinal Epithelial Cells
119, 123
Intestinal and hepatic cells are more sensitive to DON alone than other mycotoxins
OTA-DON is the most toxic combination for intestinal cells
AFB1-DON is the most toxic combination for hepatic cells
DON alone is believed to cause various chronic intestinal inflammatory diseases, including
Crohn’s disease and Ulcerative Colitis
AFB1-DON combination in hepatic cells showed a strong synergism, in addition to their high
individual toxicities, leading to DNA damage and high oxidative stress
81. “Despite the distinct mechanistic pathways of mycotoxins, once
combined these may lead to additive, synergistic and antagonistic toxic
effects after mixed exposure originated from different environmental
sources via gastrointestinal and inhalation routes”
119
82. Presence of Mycotoxins in the Body
ELISA techniques have detected the presence of mycotoxins in a number of tissues including:
• Urine
• Nasal polyps and secretions
• Cancerous breast tissue
• Spinal fluid
• Breast milk
• Gastric and colon tissue
• Bladder and transitional cell carcinomas
• Brain astrocytoma
• Lung
• Lymph nodes especially those with granulomatous diseases
• Renal cell tumors
83. Remediation
The most important component of treatment is complete avoidance of
further exposure to the water-damaged environment
