White blood cells, also called leukocytes, are an essential part of the immune system. There are six main types of white blood cells, including neutrophils, lymphocytes, monocytes, eosinophils, basophils, and plasma cells. They are produced in the bone marrow and other lymphatic tissues. White blood cells help defend the body by seeking out and destroying pathogens through processes like phagocytosis, where they engulf and digest bacteria, viruses and other foreign particles. Neutrophils and macrophages are especially important for phagocytosis and are the body's first responders against infection.
Lecture 8- Immunity.ppt
The immune system document defines key terminology related to symbiosis, disease, and immunology. It then describes the different types of immunity, including nonspecific and specific responses. As part of the nonspecific response, it details the immune system's physical and mechanical barriers, as well as chemical factors like lysozymes and complement proteins. It also explains the roles of phagocytes such as neutrophils, monocytes, and macrophages in phagocytosis and the inflammatory response.
Functional organization of the Immune System
Lymphocytes are the main cells of the immune system and are responsible for the specific immune response. There are two main types of lymphocytes - T lymphocytes and B lymphocytes. T lymphocytes attack invaders directly through cell-mediated immunity, while B lymphocytes produce antibodies and perform antibody-mediated immunity against bacteria. Natural killer cells provide immediate defense against viruses and cancer cells by destroying infected or malignant cells upon first exposure. Monocytes circulate in the blood and differentiate into tissue macrophages that phagocytose pathogens. Dendritic cells present antigens to lymphocytes to initiate immune responses.

Immune system plays an important role in safeguarding the organisms from pathological and allergic invaders. This is a brief presentation of explanation of role cells and organs in the immune mechanism. The slides are all about lymphocytes, phagocytes, monocytes, thymus, spleen, and some WBCs
Anatomy and biology of immune response
The document summarizes key aspects of anatomy and biology related to the immune system. It discusses how the bone marrow and liver produce immune cells, and the role of soluble mediators in immune cell maturation. It also describes the main immune cell types - granulocytes, monocytes, dendritic cells, lymphocytes, and natural killer cells - and the primary and secondary organs of the immune system, including the bone marrow, thymus, lymph nodes, spleen, and mucosa-associated lymphoid tissue.
Cells involved in Immunity
White blood cells, also called leukocytes, circulate throughout the body in blood and lymphatic vessels. They are stored in lymphoid organs such as the thymus, spleen, bone marrow, and lymph nodes. The main cells of the immune system are lymphocytes (T cells, B cells, NK cells), phagocytes (monocytes, macrophages), granulocytes (neutrophils, basophils, eosinophils), and dendritic cells. Lymphocytes develop from bone marrow and have roles in destroying compromised cells or producing antibodies. Phagocytes surround and destroy pathogens through phagocytosis. Granulocytes contain granules and have roles in attacking bacteria. Dendritic cells
The bone marrow is the wellspring of numerous immune and blood cells.pdf
The bone marrow is the wellspring of numerous immune and blood cells in the solid grown-up
creature. In the event that the bone is part the long way, a stamped contrast in tissue is taken
note. Part of the tissue is red, which is the wellspring of red and white platelets. The other bit is
yellow fat tissue that is idle. Amid a contamination, the yellow marrow can be reactivated to
wind up red marrow to help in the generation of bigger quantities of safe cells.
In the grown-up creature, every single insusceptible cell begin from hematopoietic
undifferentiated organisms situated in the bone marrow. Stems cells always isolate and separate
into different sorts of resistant cells affected by cytokines. the starting point of the cells of the
resistant framework. Cytokines are little flagging proteins that direct the conduct of the cells of
the body. The bone marrow is at last in charge of the union of eight sorts of cells: red platelets,
platelets, neutrophils, basophils, eosinophils, pole cells, monocytes/macrophages, T lymphocytes
and B lymphocytes. Some of these cell sorts develop in the bone marrow itself, while others
relocate through the circulatory framework and experience last development in different tissues.
Now, we will investigate quickly at a portion of the components of the cells made in the bone
marrow as a prologue to their capacity. You will take in more insights about every resistant cell
sort later when we cover particular insusceptible reactions..
The real cell sort made by the bone marrow is red platelets. Platelets likewise shape in the bone
marrow and help with development of blood clumps taking after any sort of harm. Neither of
these cell sorts assumes a part in the resistant reaction, yet we specify them here in light of the
fact that they likewise start from bone marrow undifferentiated organisms and are basic segments
of the blood.
Polymorphonuclear granulocytes is the general term given to neutrophils, eosinophils and
basophils. The primary portion of the name portrays the presence of the core that is by all
accounts split into various diverse flaps. In actuality, the core is coterminous, yet contains
numerous infoldings, which give it a polynuclear appearance. Whatever is left of the name
originates from the presence of the cytoplasm, which looks spotted. The cytoplasm is loaded
with granules that contain mixes and chemicals imperative in satisfying the capacity of every cell
sort. Polymorphonuclear granulocytes make up 50-70% of the white platelets found in blood.
They last just around three days and must be supplanted at a rate of 80 million cells for each
moment.
Neutrophils are the most well-known sort of polymorphonuclear cells, making up 90% of
granulocytes in the blood. These cells work as phagocytes in assaulting and decimating
irresistible specialists. We will cover their parts in more detail when we examine phagocytes.
Eosinophils make up 2-5% of granulocytes in the blood, however this number can rise

Echinacea and immune system
Echinacea has broad effects on the immune system by affecting different types of white blood cells and immune system components. It enhances macrophage function, which helps filter the blood and signals other immune cells to mount an attack. It also stimulates T cells and B cells, increasing immune responses. Echinacea boosts natural killer cells, which help fight cancer and viruses. Additionally, echinacea activates the complement system, which is one of the body's first lines of defense, and has been shown to have antiviral properties against influenza, herpes, and cold viruses. Through these diverse effects on the immune system, Echinacea provides robust support for immune health.
Immunology
The document provides an overview of the immune system, including both the innate and adaptive immune systems. It discusses the key components and cells involved in each system.
The innate immune system is the first line of defense and includes physical barriers, defense mechanisms, and general immune responses. It uses nonspecific responses to quickly identify and respond to pathogens. The adaptive immune system has a delayed but stronger and more targeted response. It uses B cells and T cells to produce antibodies and mount a cell-mediated response. Together, the innate and adaptive immune systems work to protect the body from disease.
WBC AND IMMUNITY
1. The document discusses white blood cells (WBCs) or leukocytes, which are colorless formed elements of blood that play an important role in the body's defense mechanism.
2. WBCs can be classified as granulocytes (neutrophils, eosinophils, basophils) or non-granulocytes (monocytes, lymphocytes). Their numbers and types can vary under different physiological and pathological conditions.
3. Both innate and acquired immunity involve WBCs. Innate immunity provides initial defense through cells and proteins. Acquired immunity develops after exposure to specific pathogens and involves T lymphocytes and B lymphocytes that provide cellular and humoral immunity respectively.

The immune system consists of lymphatic organs, antibodies, and regulatory agents that work together to defend the body against diseases. The primary lymphatic organs are the red bone marrow and thymus gland, where lymphocytes originate and mature. Lymphocytes then congregate in secondary lymphatic organs like the spleen, lymph nodes, and tonsils. When tissue rejection occurs, the immune system recognizes and destroys cells bearing foreign MHC antigens. Diseases of the immune system include autoimmune disorders, where the immune system mistakenly attacks the body's own cells, and immune deficiencies, where the immune system is unable to adequately protect against disease.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

Immunology
- 1. Pathology Presentation: Immunology Group Members: Aliza Riaz 3 Aqsa Zafar Asma Javed
- 2. COMPONENTS OF IMMUNE SYSTEM 1. Organs 2. Cells 3. Molecules
- 3. ORGANS Tonsils and adenoids Thymus Lymph nodes Spleen Payer’s patches Appendix Lymphatic vessels Bone marrow
- 5. CELLS LYMPHOCYTES T-lymphocytes B-Lymphocytes, plasma cells Natural killer lymphocytes MONOCYTES, Macrophage GRANULOCYTES Neutrophils Eosinophils Basophils
- 6. 1-B-Lymphocytes Are responsible for humoral(antibody mediated) immunity. They are produced and matured in bone marrow. They are preprocessed in liver during mid fetal life and in bone marrow in late fetal life and after birth. In birds they are processed in Bursae of Fabricius, hence so named. They are much less mobile than T cells and spend much of their time in the lymphoid tissue like spleen and lymph nodes.
- 7. 2. T-lymphocytes are in majority are responsible for cell mediated immunity (specific defense). They are formed in bone marrow but Final processing of T cells occurs in Thymus gland. A hormone thymosin is produced by thymus gland and promotes maturation of T cells. Mature T cells is programmed to recognize only one type of antigen. (highly specific) A mature T cell that recognizes chicken pox virus will not react with measles virus or a cancer cell. T cells are highly mobile cells.
- 8. 3-Natural Killer cells (NK cells) involved in immunological surveillance. Considered as the third type of lymphocyte, it is often called the non-T, non- B cell. It is derived from bone marrow. NK cell is said to be the first line of defense in specific immunity, particularly against viruses. It is not a phagocytic cell but its granules contain hydrolytic enzymes such as perforins and granzymes. These hydrolytic enzymes play an important role in the lysis of cells of invading organisms.
- 9. Monocytes Monocytes are a type of white blood cell. They are produced in the bone marrow and then enter the bloodstream. They fight certain infections and help other white blood cells remove dead or damaged cells and fight cancer cells.
- 10. Granolocytes Neutrophils: Neutrophils are a type of white blood cell. They make up the biggest number of all kinds of white blood cells. They kill and digest bacteria and fungi to help your body fight infections and heal wounds. Eosinophils: Eosinophils are a type of disease-fighting white blood cell. This condition most often indicates a parasitic infection, an allergic reaction or cancer. You can have high levels of eosinophils in your blood (blood eosinophilia) or in tissues at the site of an infection or inflammation (tissue eosinophilia). Basophils: Basophils are one of the several kinds of white blood cells you have in your body. These blood cells make up less than 1% of all of your circulating white blood cells and are the least abundant in all mammals. Basophils are a part of your immune system and are created inside of your bone marrow.
