T cell-mediated immunity to oncornavirus-induced tumors. I. Ly phenotype of precursor and effector cytolytic T lymphocytes

J C Leclerc et al. J Immunol. 1980 Feb.

Abstract

Regression of tumor induced by murine sarcoma virus (MSV) is accompanied by the formation of specific cytolytic T lymphocytes (CTL). Selection of T-cells sets by Ly phenotype determination allows separation of T sets involved in the cytolytic reaction. After MSV inoculation we demonstrate that a) Ly123+ cells contain precursors of CTL, b) direct cytolysis is mainly mediated by Ly23 cells, 3) cytolytic memory is divisible into "early" memory, carried by Ly23 cells, and "late" memory, which reverts to an Ly123 precursor population, and d) Ly1 cells are required to induce anti-MSV antibody formation.
