b cell physiology

Over the past several years, studies on normal and malignant B cells have provided new insights into the unique physiology of the germinal centre (GC). They are mature but not yet activated. Memory B cells function in a way similar to memory T cells. An abnormality of the physiological functioning of B cells.

Naïve B cells are located in the secondary lymphoid organs. The primary responsibility of B-cells involves the body's response to foreign invaders through what is known as humoral immunity. 77 One phenotypically distinct subset, designated B10 cells, has been shown to uniquely regulate T cell–mediated inflammatory responses through the production of IL-10 . Cell physiology is the biological study of the activities that take place in a cell to keep it alive. The final B cell of interest is the memory B cell, which results from the clonal expansion of an activated B cell. B cells are involved in so-called humoral immunity; on encountering a foreign substance (antigen), the B lymphocyte differentiates into a plasma cell, which secretes A further role pairs naïve B cells with naïve T cells to stop the latter from proliferating. B cells can also function as polarized cytokine-producing effector cells that influence T-cell differentiation. All lymphocytes begin their development in the bone marrow. Epub 2018 Feb 23 doi: 10.1002/cam4.1342. These cells differ in morphology from standard B and T cells in that they contain a large amount of cytoplasm packed with the protein-synthesizing machinery known as rough endoplasmic reticulum. Animal cells, plant cells and microorganism cells show similarities in their functions even though they vary in structure. T cells and B cells differ in their functions, like T cells are known to develop various immune response such as invading bacteria from body’s immune system, virus attacks, not supporting the organ transplant, etc., while B cells produce antibodies against the antigen. B-Cell Functions . B cell, One of the two types of lymphocytes (the others being T cells). 76 In addition, regulatory B cells have been described. This action has led to a new B cell subcategory – Breg cells (regulatory B cells). They lead to a stronger and faster secondary response when compared to the primary response, as illustrated below. Thus, the B cell receives signals from both its surface antibody and the T cell via its cytokines, and acts as a professional antigen-presenting cell in the process. Figure 21.4.5 – T and B Cell Binding: To elicit a response to a T cell-dependent antigen, the B and T cells must come close together. B-cells become "activated" when they encounter foreign antigens, as in foreign markers on the outside of bacteria cells during an infection. The term physiology refers to normal functions in a living organism. Naive B lymphocytes can differentiate into plasma or memory B cells. The pathophysiology of lymphoma refers to the process or processes going on inside the body that are sometimes reflected in the signs and symptoms that are identified as being indicative of lymphoma. A plasma cell is a B cell that has differentiated in response to antigen binding, and has thereby gained the ability to secrete soluble antibodies.
