B cell - Wikipedia
网页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]

网页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 lymphocytes.

网页2020年10月4日 — B cells are lymphocytes – a type of white blood cell. They are the result of multipotential cell differentiation in the bone marrow. One common cell responsible for all blood cell types. Every blood cell is derived from a single cell type – the pluripotent hematopoietic stem cell.
B cell | Description, Types, & Function | Britannica
网页2024年8月30日 — B cell, one of the two types of lymphocytes (the other is the T cells). All lymphocytes begin their development in the bone marrow. B cells are involved in so-called humoral immunity. On encountering a foreign substance (antigen), the B cell differentiates into a plasma cell, which secretes.

网页Each 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.
