B cells, also known as B lymphocytes, are a type of white blood cell of the lymphocyte subtype. [1] They function in the humoral immunity component of the adaptive immune system. [1] B cells produce antibody molecules which may be either secreted or inserted into the plasma membrane where they serve as a part of B-cell receptors. [2]
IL-2 - a cytokine key activating factor for T cells and B cells secreted by T cells. [4] Cells in early-stage activation differentiate in response to IL-2 and all B cells proliferate in the presence of IL-2. [11] IL-2 exhibits an additive affect to BCGF when both are present. [9]
Transitional B cells that survive selection against autoreactivity develop eventually into naive B cells. [3] Given the fact that only a small fraction of immature B cells survive the transition to the mature naive stage, the transitional B cell compartment is widely believed to represent a key negative selection checkpoint for autoreactive B ...
B cell: Plasma B cells; Effector B cells; Plasmocytus; 8-10 Active B cells that produces large amounts of antibodies [4] [15] Memory B cell: Lymphocyte: B cell: MBC; 8-10 Memorizes the characteristics of the antigens; Triggers an accelerated and robust secondary immune response [4] [16] Killer T cell: Lymphocyte: T cell: T lymphocyte ...
The biological basis of personality is a collection of brain systems and mechanisms that underlie human personality. Human neurobiology, especially as it relates to complex traits and behaviors, is not well understood, but research into the neuroanatomical and functional underpinnings of personality are an active field of research.
Interleukin 6 (IL6), also referred to as B-cell stimulatory factor-2 (BSF-2) and interferon beta-2, is a cytokine involved in a wide variety of biological functions. [20] It plays an essential role in the final differentiation of B cells into immunoglobulin-secreting cells, as well as inducing myeloma/plasmacytoma growth, nerve cell ...
Memory B cells that lack CD27 are generally associated with exhausted B cells or certain autoimmune conditions such as HIV, lupus, or rheumatoid arthritis. [2] [3] Because B cells have typically undergone class switching, they can express a range of immunoglobulin molecules. Some specific attributes of particular immunoglobulin molecules are ...
In immunology, a naive B cell is a B cell that has not been exposed to an antigen. These are located in the tonsils , spleen , and primary lymphoid follicles in lymph nodes . Once exposed to an antigen , the naive B cell either becomes a memory B cell or a plasma cell that secretes antibodies specific to the antigen that was originally bound.
