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 ...
T independent antigens elicit antibody production by B lymphocytes without T lymphocyte involvement. There are two distinct subgroups of TI antigens, different in mechanism of activating B lymphocytes: TI-1 antigen, which has an activity that can directly activate B cells and TI-2 antigen, which has highly repetitive structure and causes simultaneous cross-linking of specific B cell receptors ...
Lymphocyte homing receptor control of organ-specific lymphocyte trafficking is thought to prevent autoreactivity in immune responses during B and T cell differentiation. [2] Recently, lymphocyte homing has become a topic of interest for investigation of treatments for multiple sclerosis , type 1 diabetes mellitus , leukemia , and psoriasis .
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]
Central tolerance is essential to proper immune cell functioning because it helps ensure that mature B cells and T cells do not recognize self-antigens as foreign microbes. [2] More specifically, central tolerance is necessary because T cell receptors (TCRs) and B cell receptors (BCRs) are made by cells through random somatic rearrangement. [1]
