CD4 T cell

Definition

noun, plural: CD4 T cells

A form of T lymphocyte with CD4 receptor on the cell surface that recognizes antigens of a virus-infected cell.


Supplement

This type of T lymphocyte releases lymphokines upon stimulation of its recognition of antigens of a virus-infected cell. Upon its antigen recognition it is activated, stimulating, in turn, B lymphocytes and killer T lymphocytes during the antibody formation.

It is the target cell of AIDS virus, infecting and eventually killing the lymphocyte by the virus.
