title: Expression of Pgp-1 (or Ly24) by subpopulations of mouse thymocytes and activated peripheral T lymphocytes.
abstract: The expression of Pgp-1 (Ly24) by subpopulations of thymocytes was investigated and a subpopulation of Lyt-2-/L3T4-/J11d- thymocytes was identified which contained significant numbers (80%) of Pgp-1+ cells. Among freshly isolated lymph node T cells but not cortisone-resistant thymocytes, Pgp-1 expression was heterogeneous. Stimulation of T lymphocytes with either concanavalin A or the combination of phorbol myristate acetate plus calcium ionophore resulted in increased Pgp-1 expression which was found to be regulated independently of DNA synthesis and interleukin 2 receptor expression. T cells in the cerebrospinal fluid exudate of mice infected with lymphocytic choriomeningitis virus were also found to be Pgp-1+.
