B cells, unlike the other two classes of lymphocytes, T cells and natural killer cells, express B cell receptors (BCRs) on their cell membrane. [1] BCRs allow the B cell to bind to a foreign antigen, against which it will initiate an antibody response. [1] B cell receptors are extremely specific, with all BCRs on a B cell recognizing the same ...
A lymphocyte is a type of white blood cell (leukocyte) in the immune system of most vertebrates. [1] Lymphocytes include T cells (for cell-mediated and cytotoxic adaptive immunity), B cells (for humoral, antibody-driven adaptive immunity), [2] [3] and innate lymphoid cells (ILCs; "innate T cell-like" cells involved in mucosal immunity and homeostasis), of which natural killer cells are an ...
CD5-CD72 is thought to mediate B cell-B cell interaction. What differentiates B1 cells from other B cells is the variable existence of CD5, CD86, IgM and IgD. [1] B-1 B cells, in the mouse, can be further subdivided into B-1a (CD5 +) and B-1b (CD5 −) subtypes. Unlike B-1a B cells, the B-1b subtype can be generated from precursors in the adult ...
Plasma cells, also called plasma B cells or effector B cells, are white blood cells that originate in the lymphoid organs as B cells [1] [2] and secrete large quantities of proteins called antibodies in response to being presented specific substances called antigens.
B lymphocytes are the cells of the immune system that make antibodies to invading pathogens like viruses. They form memory cells that remember the same pathogen for faster antibody production in future infections. In immunology, a memory B cell (MBC) is a type of B lymphocyte that forms part of the adaptive immune system.

They include T cells and B cells and are part of the larger category of ‘tumor-infiltrating immune cells’ which consist of both mononuclear and polymorphonuclear immune cells, (i.e., T cells, B cells, natural killer cells, macrophages, neutrophils, dendritic cells, mast cells, eosinophils, basophils, etc.) in variable proportions. Their ...
It's flu season right now, and the U.S. is in the midst of a wave that's straining hospitals. But not all influenza is the same. There are some notable differences between flu A and flu B strains ...
