Introduction: T-cells

T-cells or "T lymphocytes" are white blood cells that have a key purpose in the immune system called "cell-mediated immunity". These cells identify and attack any body cells that are infected with viruses or otherwise identified as harmful or "non-self". There are numerous types of T-cells with different purposes ranging from identifying dangers (helper T-cells) to attacking infected cells. T-cells do not produce antibodies; that function is performed by plasma cells (a type of B-cell). Although produced in bone marrow, T-cells migrate to the thymus where they mature into various sub-types with specific purposes.

Article Excerpts about T-cells

T cells small white blood cells (also known as T lymphocytes) that direct or directly participate in immune defenses. (Source: excerpt from Microbes in Sickness and in Health -- Publications, National Institute of Allergy and Infectious Diseases: NIAID)

a type of lymphocyte. T cells have T-cell receptors and, sometimes, co-stimulatory molecules on their cell surfaces. The T cell helps to orchestrate the immune system and can issue "orders" for other cells to make cytokines and chemokines. (Source: excerpt from Understanding Autoimmune Disease: NIAID)

Summary Information: T-cells

T-cells: T cells are one of three types of lymphocytes, a kind of white blood cell. T cells have the ability to recognize antigens and can help to wipe them out. T cells can also provide a "memory" for the develoment of immunity to specific pathogens. T cells are produced in the bone marrow, mature in the thymus. They are present in the blood but are most common in the lymphatic system.

Conditions that can afflict the T cells include leukemia, leukopenia, lymphocytic leukocytosis, lymphocytopenia, HIV, malnutrition, corticosteroid use, chemotherapy, and hereditary immunodeficiency disorders.
