CD4 T lymphocytes form a subgroup of T lymphocytes that is responsible for cell-mediated immune responses.
Synonyms
T helper cell
CD4 cells
Detailed description
T lymphocytes carrying the surface antigen CD4 are called T helper cells. After activation, they release substances that are either involved in cell-mediated immunity or that stimulate B cell immune responses. HIV infects mainly this T lymphocyte subgroup.
