How Lymphocytes Produce Antibody
The scanning electron micrograph (right) shows a human macrophage (gray) approaching a chain of Streptococcus pyogenes (yellow). Riding atop the macrophage is a spherical lymphocyte.
Cytotoxic T Lymphocytes (CTL)
Cytotoxic T lymphocytes are lymphocytes that kill other ("target") cells.
Targets may include: ...
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 White blood cells that arise in the bone marrow and mediate the immune response; include T cells and B cells.
[edit] Lymphocytes
The cells of the adaptive immune system are special types of leukocytes, called lymphocytes. B cells and T cells are the major types of lymphocytes and are derived from hematopoietic stem cells in the bone marrow.
Lymphocytes are cells that circulate in your blood that are part of the immune system. There are two main types lymphocytes: T cells and B cells. B cells produce antibody molecules that can latch on and destroy invading viruses or bacteria.
lymphocytes aid in destroying antigens in which they engulf or they take the antigen to the thrid line of defence ( B and t cells, which are specific).
lymphocytes A type of white blood cell; a component of the immune system produced by stem cells in the bone marrow.
lymphokine A molecule secreted by an activated or stimulated lymphocyte that causes physiological changes in certain other cells.
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.
B lymphocytes (B cells)
- A type of cell that produces antibodies.

Cytotoxic T lymphocytes T cells that trigger cell death by apoptosis in cells that display foreign antigens on class I MHC proteins. Also called killer T 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.
An immunoglobulin protein produced by B- lymphocytes of the immune system that binds to a specific antigen molecule. (See monoclonal antibodies, polyclonal antibodies.) Anticodon.
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.
The primary hosts for HIV are the white blood cells variously called helper T lymphocytes, helper T cells, or CD4+ T cells.
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.
Activated TH 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.
The lymphocytes which make antibodies also engage in cell division. All eukaryotic cells divide by a process called mitosis.
It contains many lymphocytes and frequently red blood corpuscles. Granules and bacteria are also taken up by the lymph from the connective-tissue spaces, ...
B cells: 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.
Not only do your nodes remove cells, they also create cells called lymphocytes. Those lymphocytes are white blood cells used by the immune system to produce antibodies or hunt down pathogens and eat them (using phagocytosis).
A decrease in the number of lymphocytes (a variety of white blood cells) in the blood, which may occur in a wide variety of diseases.

Around half of individuals who avoid the virus while young are infected in the teenage years and develop a disease called mononucleosis. In this disease, lymph nodes swell painfully as our immune system produces large numbers of lymphocytes to ...
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.
