Ion channels activated by specific Ti or T3 antibodies in plasma membranes of human T cells.


T lymphocytes are activated to proliferate via a surface membrane receptor recognizing the antigen/major histocompatibility complex. This membrane component is comprised of at least five polypeptide subunits, collectively termed the Ti-T3 receptor complex. A transient increase in cytosolic free calcium occurs as an early event in the T-cell activation… (More)
