B Cells: Types and Function - Cleveland Clinic
WEBFeb 1, 2023 · B cells are a type of white blood cell that makes infection-fighting proteins called antibodies. B cells are an important part of your immune system, your body’s defense against harmful pathogens (viruses, bacteria and parasites) that enter your body and make you sick. B cells and T cells are a specific type of white blood cell called ...
B Cells and Antibodies - Molecular Biology of the Cell - NCBI …
WEBEach B cell produces a single species of antibody, each with a unique antigen-binding site. When a naïve or memory B cell is activated by antigen (with the aid of a helper T cell), it proliferates and differentiates into an antibody-secreting effector cell.
B cell - Wikipedia
WEBB 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] . When a naïve or memory B cell is activated by an antigen, it proliferates and differentiates into an antibody-secreting effector cell, known as a plasmablast or plasma cell. [2] .
