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]
The immunoglobulin superfamily (IgSF) is a large protein superfamily of cell surface and soluble proteins that are involved in the recognition, binding, or adhesion processes of cells. Molecules are categorized as members of this superfamily based on shared structural features with immunoglobulins (also known as antibodies); they all possess a ...
The first epitope-based vaccine was developed in 1985 by Jacob et al. [28] Epitope-based vaccines stimulate humoral and cellular immune responses using isolated B-cell or T-cell epitopes. [28] [22] [17] These vaccines can use multiple epitopes to increase their efficacy. [28] To find epitopes to use for the vaccine, in silico mapping is often ...
B Cell Growth and Differentiation Factors (also known as BCGF and BCDF) are two important groups of soluble factors controlling the life cycle of B cells (also referred to as B lymphocytes, cells which perform functions including: antibody secretion, antigen presentation, preservation of memory for antigens, and lymphokine secretion). [1]
Physiological psychology studies many topics relating to the body's response to a behavior or activity in an organism. [3] It concerns the brain cells, structures, components, and chemical interactions that are involved in order to produce actions. [4]
T-independent memory B cells. T-independent memory B cells are a subset called B1 cells. These cells generally reside in the peritoneal cavity. When reintroduced to antigen, some of these B1 cells can differentiate into memory B cells without interacting with a T cell. [4] These B cells produce IgM antibodies to help clear infection. [20]
A B-cell receptor includes both CD79 and the immunoglobulin. The plasma membrane of a B cell is indicated by the green phospholipids. The B- cell receptor extends both outside the cell (above the plasma membrane) and inside the cell (below the membrane). The B-cell receptor (BCR) is a transmembrane protein on the surface of a B cell.
This is the organism's ability to tolerate the introduction of cells prior to the development of an immune response as long as it occurs early in the organism's development. There are a vast number of lymphocytes occurring in the immune system, ranging from cells that tolerate self tissue to cells that do not.
