The document discusses renal function tests which evaluate how well the kidneys are functioning. There are three main groups of renal function tests: urine and blood analysis, assessment of renal clearance, and additional specialized tests. Renal function tests are useful for early detection of kidney damage, monitoring disease progression and treatment effectiveness, and predicting when renal replacement therapy may be needed. Common tests include analysis of urine volume, appearance, constituents, and sediment as well as blood tests of urea and creatinine levels. Clearance tests measure the glomerular filtration rate using markers like inulin, creatinine, or iohexol.
Prokaryotic cells include bacteria, blue-green algae, mycoplasma, and PPLO. They lack a nucleus and other membrane-bound organelles. The cell envelope consists of an outer glycocalyx layer, a peptidoglycan cell wall, and an inner plasma membrane. The cell contains genomic DNA and sometimes plasmid DNA. Ribosomes are the site of protein synthesis and prokaryotic ribosomes are 70S. Inclusion bodies store reserved materials in the cytoplasm.

Antibodies are globulin proteins called immunoglobulins that are produced in response to antigens. There are five classes of immunoglobulins - IgG, IgM, IgA, IgD, and IgE - which have different structures and functions such as protecting blood, mucous membranes, or mediating allergic reactions. Immunoglobulins have light and heavy chains that give them antigen binding sites and allow for different subclasses within each class.
This document provides information on reticluocyte count, which assesses bone marrow erythropoietic activity. It describes how a reticluocyte is an immature red blood cell that contains RNA aggregates. The routine reticluocyte count involves staining a blood sample and counting the number of reticluocytes per 1000 red blood cells under a microscope. Quality control measures and different counting methods using a calibrated disk are discussed. The reticluocyte percentage, absolute count, corrected count, and production index are defined and their clinical significance and reference ranges are explained.
T-cells are a type of white blood cell that play a major role in the immune system by fighting infection. There are different types of T-cells that act in various ways to identify and destroy pathogens. T-cells mature and develop in the thymus gland, where they are selected and educated to recognize the body's own cells and mount immune responses against foreign threats. T-cells recognize antigens presented on other cells through molecules of the major histocompatibility complex and are activated through a process that involves antigen presentation, costimulatory signals, and cytokine communication.
This document discusses 3D cell culture systems and their application in drug discovery. It notes that 3D cell cultures better mimic the in vivo cellular environment compared to traditional 2D cultures. Cells in 3D cultures exhibit different gene expression, morphology, proliferation rates, and responses to drugs compared to 2D cultures. This makes 3D cultures more predictive of in vivo responses during drug testing. The document outlines different types of 3D culture systems, such as scaffold-based, scaffold-free, spheroids and organoids. It also discusses advantages of 3D cultures for applications in areas like developmental biology, disease modeling, regenerative medicine, and personalized drug testing.

The word Hemopoiesis refers to the production & development of all the blood cells
The document summarizes B cell generation, activation, and differentiation. It describes how B cells develop in the bone marrow through antigen-independent maturation and Ig-gene rearrangement. Upon leaving the bone marrow as naive B cells, they circulate and can become activated upon interacting with antigen in secondary lymphoid organs. Activated B cells then proliferate and differentiate into either antibody-secreting plasma cells or memory B cells. The response is regulated through feedback and cytokines to control antibody production and memory responses.
This document summarizes the development and functions of T and B lymphocytes. It discusses how they develop from stem cells in the bone marrow or thymus, and how T cells undergo selection processes in the thymus. It describes the roles of cytotoxic T cells, helper T cells, and B cells, and how B cells differentiate and produce antibodies. The document also provides a brief overview of HIV/AIDS, including the virus structure and life cycle.
This document provides protocols for several basic staining techniques used in microbiology, including simple staining, Gram staining, endospore staining, and capsule staining. Simple staining involves using a single basic dye like methylene blue or crystal violet to determine cell shape, size, and arrangement. Gram staining is a differential staining technique used to distinguish between Gram-positive and Gram-negative bacteria based on differences in their cell walls. Endospore staining uses malachite green and safranin dyes to identify bacterial endospores. Capsule staining employs India ink as a negative stain along with crystal violet to visualize uncharged polysaccharide capsules that help bacteria attach to surfaces.
The document discusses hematopoiesis, the production and development of blood cells. It begins in the fetal liver and spleen and later continues in the bone marrow. There are two types of hematopoiesis - medullary, which occurs in the bone marrow, and extramedullary, which can occur in other tissues like the liver and spleen. The process is regulated by hematopoietic growth factors and involves stem cell differentiation down myeloid or lymphoid lineages to produce the various mature blood cell types.
Hematopoiesis is the formation of blood cellular components from hematopoietic stem cells. Hematopoietic stem cells can differentiate into red blood cells, lymphocytes, or non-lymphocyte white blood cells. In fetal development, hematopoiesis occurs in the yolk sac and liver before shifting to the bone marrow in adults. Stem cells are capable of self-renewal and differentiation into various blood cell types. Growth factors play an important role in hematopoiesis by influencing the differentiation and proliferation of blood cell lineages from hematopoietic stem cells.

This document discusses three types of antigenic determinants found on immunoglobulins: isotypes, allotypes, and idiotypes. Isotypes characterize the classes and subclasses of heavy chains. Allotypes are specified by allelic forms of immunoglobulin genes. Idiotypes are unique antigenic determinants present on individual antibody molecules that are created by the hypervariable regions. Idiotypes can serve as V region markers and play a role in regulating immune responses. Anti-idiotype vaccines have potential applications in vaccines and cancer treatment.
Eosinophils are a type of white blood cell that develop from stem cells in the bone marrow under the influence of cytokines like IL-3, GM-CSF, and IL-5. They mature through stages like myeloblast, promyelocyte, and myelocyte before becoming segmented cells. Mature eosinophils contain granules with toxic proteins and travel to tissues to fight parasites and support allergic responses. Eosinophils play roles in both promoting inflammation and resolving it by undergoing apoptosis when no longer needed.
Transplantation refers to transferring cells, tissues or organs from one site to another. The first successful human kidney transplant occurred between identical twins in Boston in 1954. There are four main types of transplants - autograft, isograft, allograft, and xenograft - which differ based on the genetic similarity between the donor and recipient. Autografts have no immune response, while xenografts between different species have the most vigorous rejection response.
This document provides an overview of metabolism and cellular respiration. It defines metabolism as the set of anabolic and catabolic processes that occur in cells. Anabolism involves building complex molecules from simple precursors and requires energy, while catabolism breaks down complex molecules into simpler ones and releases energy. Cells couple exergonic (energy-releasing) reactions like cellular respiration to endergonic (energy-requiring) anabolic reactions to maintain order. The document discusses key concepts like the laws of thermodynamics, redox reactions, and how enzymes lower the activation energy of reactions to speed them up. It also provides examples of specific anabolic and catabolic pathways.
The complement system is part of the innate immune system and consists of over 30 proteins. It was originally identified in the 1890s by Jules Bordet and Paul Ehrlich as a heat-labile component of serum that enhanced the ability of antibodies to kill bacteria. There are three complement activation pathways: the classical pathway which is initiated by antibody-antigen complexes, the lectin pathway which is activated by mannose-binding lectin, and the alternative pathway which is spontaneously activated by microbial surfaces. Complement activation results in opsonization, inflammation, and formation of the membrane attack complex to kill microbes. Deficiencies in specific complement components can increase susceptibility to certain infections.
This document discusses several concepts related to homeostasis and the body's adaptive mechanisms:
1. Homeostasis refers to the body's ability to maintain stable internal conditions like temperature and pH levels, despite changes in the external environment. This allows for optimal metabolic efficiency.
2. Negative feedback control mechanisms help regulate homeostasis. When a condition moves outside the normal range, hormones stimulate a response to correct it, then secretion decreases once the condition is corrected.
3. Hans Selye's research on stress identified the general adaptation syndrome, in which the body progresses through alarm, resistance, and exhaustion stages in response to stressors. The stress response aims to concentrate efforts at the site demanding adaptation.
4. Fact
Membrane carbohydrate and their significance in cellular recognitionGirish Kumar K
Membrane carbohydrates play an important role in cellular recognition. They are attached to lipids and proteins on the extracellular surface of the cell membrane, forming glycolipids and glycoproteins. These carbohydrate chains can consist of 2-60 monosaccharide units and give cells their identity, allowing the immune system to distinguish between self and non-self cells. The distribution of carbohydrates is asymmetric, with the extracellular side containing oligosaccharides that mark the cell as self and allow interaction with other cells, while the intracellular side has few carbohydrates and anchors to the cytoskeleton.
This document summarizes several organ-specific autoimmune disorders:
1. Hashimoto's thyroiditis causes inflammation and damage to the thyroid gland through autoantibodies against thyroid proteins. This leads to hypothyroidism.
2. Autoimmune anemias include pernicious anemia caused by intrinsic factor antibodies impairing vitamin B12 absorption, and autoimmune hemolytic anemia where antibodies lyse or phagocytose red blood cells.
3. Goodpasture's syndrome features antibodies against lung and kidney basement membranes, activating complement and damaging these organs through inflammation.
4. Type 1 diabetes results from an autoimmune destruction of insulin-producing pancreatic beta cells by cytotoxic T cells and
This document discusses how gut microbiota can be an etiological factor in Autism Spectrum Disorder (ASD). It describes how early colonization and homeostasis of gut microbiota is important for health. Dysbiosis or imbalance of gut microbiota has been associated with ASD and various dietary and environmental factors can influence the development and composition of gut microbiota in infants and children. The document examines how factors like maternal stress, breastfeeding, diet, and use of probiotics/prebiotics can help manipulate imbalanced gut microbiota and potentially help with symptoms of ASD.

Indirect methods involve culturing viruses in cell lines or eggs and observing cytopathic effects or hemagglutination. Serology detects rising antibody titers between acute and convalescent patient samples or presence of IgM. Newer molecular techniques like PCR have increased sensitivity but require skill and specialized equipment. Proper specimen collection and a combination of direct, culture and serology tests
The document discusses the different types of neuroglia, or non-neuronal cells, in the central and peripheral nervous systems. It describes six main types of neuroglia: oligodendrocytes that produce myelin in the CNS, astrocytes that support neurons structurally and metabolically, ependymal cells that line ventricles, microglia that perform immune functions, Schwann cells that myelinate nerves in the PNS, and satellite cells that cover neuronal cell bodies in ganglia. Neuroglia outnumber neurons 10:1 and play crucial roles in insulation, support, repair and immune defense of the nervous system.
Glial cells - Neurobiology and Clinical AspectsRahul Kumar
Glial cells outnumber neurons in the central nervous system and provide support and protection for neurons. There are several types of glial cells - astrocytes, oligodendrocytes, microglia, and ependymal cells. In disease states, glial cells can become reactive or activated and contribute to conditions like stroke, cerebral edema, Alzheimer's disease, neuropathic pain, epilepsy, and glioma. The document provides an overview of glial cell types, functions, pathophysiology, and their involvement in specific nervous system diseases and conditions.
Antigen-antibody interactions can be quantified using various serological tests. Common types include precipitation tests like immunodiffusion that form visible precipitate lines, agglutination tests where antigens clump together, neutralization tests using viruses and complement fixation assays. Enzyme-linked immunosorbent assays (ELISAs) are now widely used as they are sensitive, specific and can be quantitative or qualitative. Fluorescent antibody techniques use fluorescent dyes to label antibodies or cells for detection under a microscope.
Neuroglia are cells that provide support and protection for neurons in the central nervous system. There are several types of neuroglia, including astrocytes which provide energy and structural support for neurons, microglia which remove dead material, and oligodendrocytes which myelinate axons in the central nervous system. Schwann cells perform a similar role of myelinating axons in the peripheral nervous system. Myelination allows for faster nerve impulse transmission along myelinated axons.

Los oligodendrocitos producen la mielina de los axones en el SNC. La microglia actúa como células fagocíticas para eliminar desechos.
This document discusses various infections that can occur during pregnancy and affect the fetus. It covers viral infections like rubella, measles, cytomegalovirus and herpes which can cause birth defects or complications if the mother is infected during pregnancy. It also discusses bacterial infections like group B streptococcus, gonorrhea and chlamydia which can lead to preterm birth or infection of the newborn. The document provides details on potential issues, screening and treatment recommendations for each infection.
Autism is a developmental disorder that appears in early childhood and affects social and communication skills. Boys are affected more than girls. While the causes are unknown, early signs may include lack of speech, repetitive movements, lack of eye contact and social skills. Treatment options include applied behavior analysis therapy, occupational therapy, speech therapy and sometimes medications to treat related symptoms. Diet changes eliminating gluten have helped some children with autism.
The document discusses the controversy around the increasing rates of autism diagnosis and possible environmental contributions like vaccines. It notes that as childhood vaccines containing thimerosal increased, so did autism rates. While some research suggests thimerosal may plausibly be linked to autism and related disorders, government agencies deny any causal link. The document also summarizes evidence that mercury exposure during fetal and early childhood development can significantly contribute to autism and outlines past research on links between autism and toxic metals like mercury.
This document provides an overview of autism including:
1. Autism is a developmental disorder appearing in the first 3 years that affects social and communication skills.
2. It was first described by Kanner in 1943 and prevalence is estimated at 2-6 per 1000 individuals.
3. Prognosis depends on severity but proper therapy can help individuals improve socialization and live independently.
Both research articles discuss the role of specific proteins in human diseases. The first discusses how poor control of amyloid beta and tau proteins may be key to the progression of Alzheimer's disease. It found these proteins are less regulated in brain regions most vulnerable to the disease. The second identifies two Zika virus proteins, NS4A and NS4B, that may be responsible for microcephaly cases. Identifying these target proteins represents an important step towards potential prevention or treatment strategies for both conditions.

This study examines synaptic changes in a mouse model of infantile Batten disease. Researchers isolated synapses from mouse brain regions and identified protein differences between healthy and diseased synapses. They found that synaptic breakdown begins earlier in certain brain regions, suggesting some synapses are more vulnerable than others. The team then used a fruit fly model of Batten disease to test whether modifying levels of candidate proteins identified in mouse synapses could slow disease progression, identifying potential therapeutic targets.

The document provides an overview of Alzheimer's disease including its causes, symptoms, diagnosis and potential treatments. It discusses how the disease is characterized by progressive cognitive decline and brain cell loss and death. The main causes proposed are the amyloid hypothesis, which suggests beta-amyloid plaques are fundamental, and the cholinergic hypothesis, which implicates reduced acetylcholine levels. The mechanisms involve plaque and tangle formations that disrupt cell signaling in the brain and its neuron transport system.
Elevated levels of the cytokine interleukin-6 (IL-6) have been found in the brains and cerebrospinal fluid of individuals with autism spectrum disorder. A review of literature found that IL-6 plays an important role in central nervous system development and is normally expressed at low levels, but chronic over-expression of IL-6 in mice causes neurological alterations. Studies also found IL-6 was significantly increased in the cerebellum of autistic patients compared to controls. Additionally, over-expressing IL-6 in cerebellar granule cells in vitro impaired cell adhesion and migration and stimulated excessive formation of excitatory synapses, suggesting elevated IL-6 may contribute to autism pathogenesis by disrupting neural
The Role Of Cytokines On Immune PrivilegeKaty Allen
- Immune privilege sites like the brain actively suppress inflammation to protect delicate tissues from damage. Cytokines play a role in maintaining this immune privilege.
- Experiments on mice found that chronic early-life stress impaired microglial function and rewired the brain's stress response pathways, causing depression-like behaviors in adulthood. Treating the stress hormone CRH reversed these effects.
- Exposure to toxins in tobacco smoke during development can alter brain cell proliferation, synaptic activity, and microglial function, potentially leading to neurological and cognitive impairments.
Notes On The And Its Effects On Body And Body EssayMiles Priar
1. The document discusses the myelin sheath and its importance for rapid saltatory conduction in the nervous system. Myelin increases conduction velocity by increasing membrane resistance and decreasing capacitance, allowing action potentials to propagate faster along axons.
2. Diseases like multiple sclerosis and Alzheimer's involve demyelination, which disrupts normal neural signaling and cognitive functions that depend on it.
3. One study examined myelin regeneration in adult mice and found that new oligodendrocytes grew and differentiated in response to injury or demyelinating conditions. This suggests the potential for remyelination in diseases characterized by myelin breakdown.
1. The document reviews literature on the relationship between immune system factors and brain development in autism disorder.
2. It finds that pro-inflammatory cytokines like IL-6 have been associated with autism and can impair neural cell adhesion/migration and synapse formation when overexpressed.
3. The timing of immune system disturbances and brain development may provide insights into autism pathogenesis.
Stem cells may provide a promising new treatment for glaucoma. There are three main types of stem cells - embryonic, adult-derived, and induced pluripotent stem cells. Embryonic stem cells would be ideal due to their ability to differentiate but have ethical and safety issues. Adult stem cells do not have these issues but are more limited. Induced pluripotent stem cells could offer the advantages of embryonic stem cells without ethical issues but require more research. Stem cell therapy may help treat glaucoma by replacing damaged retinal ganglion cells and slowing vision loss, providing a cure where current treatments only manage symptoms. However, more research is still needed to determine the optimal stem cell type and safely apply this as

Alzheimer disease (AD) is: Chronic neurodegenerative disorder
The leading cause of dementia
According to Etindele Sosso, Nakamura & Nakamura (2017), as of 2015, 29.8 million people had AD.
Most prevalent among people whose ages are 65 years and above.
Alzheimer disease (AD) is a chronic neurodegenerative disorder that normally starts and gradually progresses with the brain cells dying off. Leading to memory loss. The leading cause of dementia which affects an individual cognitive, social and behavioral skills that destroy the capability of a person to function properly.According to Etindele Sosso, Nakamura & Nakamura (2017), as of 2015, there were 29.8 million people globally who had AD. It mostly starts in people whose ages are over 65 years.

Neural tube defects: Importance of Folic Acid and Vitamin B12 intakeVijaya Sawant,PMP, OCP
Birth defects are a global problem, but their impact is particularly severe in middle and low income countries where more than 94 percent of the births with serious birth defects and 95 percent of the deaths of these children occur. Serious birth defect can be lethal. For those who survive, these disorders can cause lifelong mental, physical, auditory or visual disability. The report shows that at least 3.3 million children under five years of age die from birth defects each years. More than 70% of birth defects can be prevented. Educate the community about the birth defects and the opportunities for effective care and prevention.
Autism is a neurodevelopmental disorder that causes problems with social interaction, communication, and behavior. It is caused by genetic mutations that impact neuronal development in the brain. While autism can cause challenges, research is exploring the molecular mechanisms and genetic factors that contribute to the disorder in order to develop improved diagnostic tests and treatments.
WHAT IS THERAPEUTIC CLONING?#SciChallenge2017giulia api
Cloning is the process of creating a genetically identical copy of an organism. There are several types of cloning including reproductive cloning to create an organism with identical genetics to a donor, therapeutic cloning to create stem cells for medical research and treatment, and productive cloning to create selected organs or tissues. Therapeutic cloning involves transferring the nucleus of a donor cell into an egg cell to produce stem cells that can be used to treat degenerative diseases like diabetes, Alzheimer's, and Parkinson's. Stem cells have the potential to differentiate into many cell types and are a promising area of research for regenerative medicine and disease treatment.
The document discusses two research articles about Alzheimer's and Parkinson's diseases. For Alzheimer's, the article discusses how tau proteins jump between neurons using extracellular space and how blocking the protein in this space could help control the spread of Alzheimer's in the brain. For Parkinson's, the article discusses how a mutant LRRK2 gene promotes alpha-synuclein inclusions and how inhibiting this gene could decrease inclusions and pave the way for new treatments. Recognizing the cellular and genetic factors involved in these diseases can help identify causes and potential new treatment targets.

11
What are glial cells?
• Most common cells in the central nervous
system (CNS)
• They provide support and protection for the
neurons in the brain
• Control communication between neurons
• Control blood flow in the brain
• There are three types of glial cells: astrocytes,
oligodendrocytes and the microglia
Types and functions of the glial cells
• Microglia – brain’s immune system cells, they
are in charge of neurotransmission
• Astrocytes – in charge of neurotransmission
(similar to the microglia) and they also
provide metabolic support to the neurons
• Oligodendrocytes – produce myelin which
acts like an electrical wire insulation in the
neurons

Microglial Cells are essential in
brain development
• Microglial are not only are our brain’s
immune system cells
• They influence synaptic development
and connectivity.
• They regulate brain development by
microglia do the trimming of the extra
synapses

Microglial cells are not only our brain’s immune system cells, but also are essential
in the normal and developing brain. They influence synaptic development and
connectivity.
www.stopcallingitautism.org www.stopcallingitautism.orgespanol
The figure above shows the dynamic interaction of microglial processes with the tripartite synapse(A) Microglial
processes (red) dynamically contact the cellular compartments of the tripartite synapse: pre- and postsynaptic
neuronal terminals (in brown) as well as the enwrapping perisynaptic astroglial process (in blue).(B) The electron
micrograph (EM) specifically shows a microglial process (m) contacting both the pre- and postsynaptic compartment.
13. Microglial Activation Leads to
Brain Dysfunction In Autism
13
Microglial cells when activated
wrap too many brain connections
and destroy them.
When the microglial cells become chronically activated they destroy too many
brain connections. In autism this leads to brain underconnectivity and dysfunction.
www.stopcallingitautism.org www.stopcallingitautism.orgespanol
The figure above shows the synaptic pruning by microglial processes. (A) The stability and maintenance of
presynaptic terminals and postsynaptic spines is determined by microglia in a three-step process called synaptic
pruning composed of contact, engulfment, and phagocytosis of presynaptic terminals. (B) The electron
microphotograph shows ultrastructural interactions between microglia (red) and synapses (brown) in the mouse
visual cortex.

15. Role of glial cells in the gut issues
in autism
15
Many individuals with autism often suffer from GI issues
including food allergies, constipation, diarrhea, intestinal
bowel disease (IBD), irritable bowel syndrome (IBS), etc…
Often referred to as the “second brain”, the enteric nervous
system (ENS) controls the function of the digestive tract.
The enteric nervous system can operate independently
from the brain
Similar to the neurons found in the brain, the neurons in the
enteric nervous system, are surrounded by glial cells.
Glial cells in the central nervous system (CNS) can
communicate with the glial cells in the enteric nervous
system (ENS)
The enteric nervous system is
composed of both neurons and glia.
Recent evidence indicates that enteric
glia–which vastly outnumber enteric
neurons–are actively involved in the
control of gastrointestinal
functions

16. Role of glial cells in the gut issues
in autism
16
The glial cells in the digestive system are known as enteric
glial cells (EGCs)
EGCs can be both protective and destructive in the gut
EGCs have an important role in maintaining the integrity of
the mucosal barrier of the gut
EGCs are involved in basic gut functions, such as the
regulation of peristalsis, blood flow and the modulation of
the immune and inflammatory processes
In autism, glial cells in both the brain and in the digestive
system don’t work correctly causing the neuron
underconnectivity that leads to the neurological and GI
symptoms

17. Are children with autism different?
17
Children with autism suffer from different neurological and medical
problems, but the root cause is the same… Microglial Activation
• Seizures - Microglial activation exacerbates seizure activity
• Motor Skills Disorders - is a result of weak or disorganized
connections in the brain.
• Mitochondrial Disorder – Elevated levels of nitric oxide (NO)
inhibits mitochondrial respiration of surrounding neurons
• Frequent Viral, Fungal, Parasitic and Bacterial Infections –
Elevated levels of NO may reduce and impair natural killer (NK)
cell function
• Eating Disorders - Alteration of the NO plays a role in eating
disorders
• Asthma and Allergies – Elevated levels of NO are found in
patients suffering from Asthma and Allergies
• Eczema – NO is an important player in eczema
• Reduced Cerebral Blood Flow – caused by excessive contraction
of brain blood vessels due to astroctytic activation
Natural Killer Cells
Natural killer cells (NK cells) are a part
of the immune system that plays an
important role in eliminating cancer
cells, viruses, bacteria, fungus and
parasites from the body.
Microglial cells control the
communication between neurons

Nitric Oxide
Nitric Oxide is a gas naturally found
in the body. NO is an important

many brain connections (synapses) are destroyed leading
to brain underconnectivity and reduced brain function
The immune cells known as microglia, which
were thought to be active in the brain only in
the presence of diseases or infections are
constantly active, they probably play a central
role in one of the most basic functions in the
brain – the creation and destruction of the
synapses.
Compared with normal control brains, the
brains of people with autism showed
evidence of an ongoing inflammatory
process in different regions of the brain
and produced by cells known as microglia

20. What can be done to regulate
the microglial cells in autism?
Autism should be treated similarly to how the Nobel Prize-winning geneticist
Dr. Mario Capecchi did. By treating the brain’s immune system (microglia).
2010 The Geneticist Winner of the Nobel Prize
Dr. Mario Capecchi,
“What we’re saying is microglia are much more
sophisticated and are actually controlling
behavior, and they have to do it by interacting
the nerve cells in your brain," Capecchi says.

According to scientists, during chronic microglial activation too many brain connections are destroyed.
If the immune system is treated successfully, the synapses can be completely regenerated.
• Children with autism must be treated with
medications that can block microglial activation.
• Also, they should be treated with medications that
can keep viruses, bacteria, fungus and parasites
under control.
• The Nobel Prize-winning geneticist Dr. Mario Capecchi says
that instead of treating mental illness the traditional way
that doctors do, with drugs to alter brain chemistry, he tried
a new approach, by treating the immune system.

• Selective serotonin reuptake inhibitors (SSRIs) are believed
to act by inhibiting the reuptake of serotonin after being
released in synapses.
• Anti psychotic (old) Haloperidol, Chlorpromazine,
Thioridazine, and Fluphenazine. They work by controlling
the intensity of the neurotransmitter dopamine in the brain.
• Anti psychotic (new) – Risperdal works in the brain, where it
affects various neurotransmitters, in particular dopamine
and serotonin
• Anticonvulsants work by blocking different
neurotransmitters
• Stimulants – Ritalin significantly increases levels of
dopamine in the brain, thereby stimulating attention and
motivational circuits that enhance one's ability to focus and
complete tasks.

For Autism

These drugs work by altering
the brain chemistry ONLY
addressing the symptoms and
not the root cause!
These drugs attempt to treat the neurological symptoms
by altering the brain chemistry. They don’t target the root
cause which is microglial activation.
24. 24
• Hyperbaric Oxygen Therapy (HBOT) works by reducing
nitric oxide levels generated when the microglial cells are
activated. When the nitric oxide levels are reduced the
astrocytes allow the blood vessels in the brain to expand
increasing blood flow and oxygen in the brain. The problem
is that the microglial cells are still activated causing many
children to regress after the HBOT therapy is over.
• Chelation works by reducing the heavy metal toxicity and
oxidative stress. Even after chelation children continue to
suffer from heavy metal accumulation. Microglial cells
generate glutathione (a powerful antioxidant), but when
they become activated the glutathione levels are reduced
not allowing the body to get rid off heavy metals effectively.
www.stopcallingitautism.org www.stopcallingitautism.orgespanol
Example Of Current Biomedical
Treatments For Autism
Nitric Oxide is a very important
inflammatory mediator. In a low
levels it is very healthy, but in
elevated levels it is very harmful to
the body
Several biomedical treatments show to be beneficial in the
treatment of autism. Many parents report improvements,
but also report regression after a period of time after the
therapies. This is caused because these treatments do not
block microglial activation directly.

Tips to Prevent Autism
In many children, autism is caused by an abnormal response in their brain’s immune
systems (microglial activation). Children with healthier and better developed immune
systems are less likely to develop autism.
Below is a list of things that are under our control that can greatly reduce the
probability of a child from developing autism.
Probiotics and Toddler Health
The immune system begins to
develop from birth as the gut
microflora becomes populated
with a variety of microorganisms.
