Lymphocytes in Biological Definition

Antibody

... showed in 1976, portions of the genome in B lymphocytes can recombine to form all the variation seen in ... or antigen affinity chromatography. If the lymphocytes that produce the antibodies can be isolated and ... links Lymphomation: Immunoglobulins How lymphocytes Produce Antibody PLOS primer: V(D)J ...

Antigen

... they start to secrete cytokines . The cytokines then activate cytotoxic lymphocytes T (CTL), antibodies secreting lymphocytes B , macrophages and other cells. Endogenous antigens ...

Immune system

... unique to every individual. T cells, a group that encompasses cytotoxic T lymphocytes ( CTLs ), the cells that kill virally-infected cells, contain ... cells. The functions of CMI are performed by T cells , also called T lymphocytes (T means they develop in the thymus ). There are two major types of T ...

Major histocompatibility complex

... It interacts exclusively with CD8+ T cells (also known as cytotoxic T cell lymphocytes or CTLs). The fate of a virus-infected cell is almost always apoptosis , ... interact exclusively with CD4+ T cells (also known as helper T cell lymphocytes or HTLs). The helper T cells then help to trigger an appropriate immune ...

Semen

... in response to the sperm. These antibodies mistakenly recognized native T lymphocytes as foreign antigens , and consequently the T lymphyocytes would fall under attack by the body's B lymphocytes . Other semen components shown to spur an immunosuppressive effect are ...

T cell

B cell

... B cells are lymphocytes that play a large role in the humoral immune response (as opposed to the cell-mediated immune response ). The abbreviation "B" stands for the ...

Full blood count

Cartilage

... the cartilage ring, causing tissue to herniate into the spinal canal . The matrix of cartilage acts as a barrier, preventing the entry of lymphocytes or diffusion of immunoglobins . This property allows for the transplantation of cartilage from one individual to another without fear of tissue ...

Cloning

... is the process of creating an identical copy of an original. A clone in the biological sense, therefore, is a single cell (like bacteria , lymphocytes etc.) or multi-cellular organism that is genetically identical to another living organism. Sometimes this can refer to "natural" clones made ...

Helper T cell

... into activated T H cells and memory T H cells. Activated T H cells secrete cytokines , proteins or peptides that stimulate other lymphocytes ; the most common is interleukin-2 (IL-2), which is a potent T cell growth factor. Activated, proliferating T H cells can differentiate into two ...
