Lymphocytes are much more common in the lymphatic system, and include the so-called "killer T-cells". The blood has three types of lymphocytes: B cells, T cells and natural killer cells.

Lymphocytes
White blood cells known as lymphocytes arise from by mitosis of stem cells in the bone marrow. Some lymphocytes migrate to the thymus and become T cells that circulate in the blood and are associated with the lymph nodes and spleen.

lymphocytes - are central to all adaptive immune responses, since they specifically recognize individual pathogens, whether they are inside host cells or outside in the tissue fluids or blood. Two categories are T and B cells.

When we talk about lymphocytes, we can separate them into the B-lymphocyte, that makes the antibodies, and the T-lymphocyte, that can then be separated into two different subsets, one that we call CD-4 and one we call CD-8.

According to our current view, the reggies subserve functions as protein scaffolds which form microdomains in neurons, lymphocytes and many other cell types across species as distant as flies and humans.

DNA was obtained from blood lymphocytes from a male donor. The library was prepared in four distinct sections designated as RPCI1, RPCI3, RPCI4 and RPCI5, respectively, each having 120 kbp average inserts.

HIV infects a number of cell types including T-lymphocytes, macrophages, dendritic cells and neurons. AIDS occurs when lymphocytes, particularly CD4+ T cells are killed off, leaving the patient unable to fight off opportunistic infections.

In resting primary T lymphocytes, most mRNA is unstable. Stimulation of primary T cells stabilized class II containing mRNAs, but not those with class I elements.

: A major family of small lymphocytes
that are
responsible for antigen-specific humoral immunity as part of the adaptive immunity. Their antigen receptors are surface immunoglobulins (antibodies).

A clone of long-lived lymphocytes, formed during the primary immune response, that remains in a lymph node until activated by exposure to the same antigen that triggered its formation. Activated memory cells mount the secondary immune response.

A human disease caused by failure of lymphocytes to die once they have finished doing their job. As a result, the spleen and lymph nodes grow large, and immune cells may attack the body's own tissues, a condition known as autoimmunity.

The genes that code for these antibodies differ from one lymphocyte to the next because when the lymphocytes are produced, different regions of the DNA are deleted so that each lymphocyte has a somewhat different version of the genes involved.

It stores excess red blood cells, destroys old cells, and is capable of acting as a reservoir holding 20-30% of all blood cells. It produces lymphocytes and serves to regulate the volume of blood cells elsewhere in the blood system.
