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 ...
Pronunciation can change over time. Dictionaries may list the most commonly used forms of words, but as language changes, dictionaries change as well. At best, any guide to suggested pronunciation can reflect the preponderance of usage. A word like immediately, for example, is variously pronounced by Americans as: ihMEEdeeuhtlee; uhMEEdeeuhtlee
This is a list of immune cells, also known as white blood cells, white cells, leukocytes, or leucocytes. They are cells involved in protecting the body against both infectious disease and foreign invaders .
In adults, absolute lymphocytosis is present when the lymphocyte count is greater than 5000 per microliter (5.0 x 10 9 /L), in older children greater than 7000 per microliter and in infants greater than 9000 per microliter. [1] Lymphocytes normally represent 20% to 40% of circulating white blood cells. When the percentage of lymphocytes exceeds ...
Although lymphocytes are usually considered mature, as seen in blood tests, they are certainly not inert. Lymphocytes can travel around the body wherever there is a need. When such needs arise, new rounds of downstream lymphopoiesis, such as cell multiplication and differentiation, may occur, accompanied by intense mitotic and metabolic activity.
Lymphocytes generate the immune repertoire by recombining the genes encoding immunoglobulins and T cell receptors through V(D)J recombination.Although there are only a few of these genes, all their possible combinations can result in a wide variety of immune repertoire proteins.

Lymphangiectasia, also known as "lymphangiectasis", [1] is a pathologic dilation of lymph vessels. [2] When it occurs in the intestines it is known as intestinal lymphangiectasia, colloquially recognized as Waldmann's disease in cases where there is no secondary cause. [3]
