B Cells British Society For Immunology Only b cells, which are antigen specific, are capable of secreting antibodies. following initial exposure to antigen, the plasma cells stop producing antibody and die. memory cells remain in greater numbers than the initial b cells, allowing the body to quickly respond to a second exposure of that antigen. B cells, also known as b lymphocytes, are immune cells that drive the humoral adaptive immune response.they are one of three types of lymphocyte in the adaptive immune response – the others being t cells and natural killer (nk) cells. 1 b cells are distinguished by their ability to produce antibodies (known as immunoglobulins (ig) when attached to b cells via a transmembrane domain), and the. B1 b cells secrete natural igm in a t cell independent manner and have a limited repertoire. they differentiate rapidly into short lived plasma cells; mz b cells reside in the marginal zone that surrounds the follicles of secondary lymphoid organs and is directly connected to the vasculature. mz b cells therefore respond to blood born antigens. T cell dependent activation of a b cell requires two signals. the first is the crosslinking of the bcrs by binding to antigen surface molecules on foreign targets or free soluble antigens. the second is signaling through the cd40 receptor on t cells (figure 3). figure 1a: human b cell development and cellular markers.

B cells mature into plasma cells that produce antibodies. each b cell is programmed to make one specific antibody. for example, one b cell will make an antibody that blocks a virus that causes the common cold, while another produces an antibody that attacks a bacterium that causes pneumonia. when a b cell encounters its triggering antigen, it. B cell development: maturation, activation, and differentiation. b cells are a type of white blood cell that plays a crucial role in the immune system. millions of b lymphocytes are generated in the bone marrow daily and exported to the periphery. the rapid and unceasing generation of new b cells occurs in a carefully regulated sequence of events.
