YR 1979 UL http://www.jimmunol.org/content/123/6/2599.abstract AB Lymphocytes responding in a “secondary” MLC-CML system, after in vitro sensitization, apparently fall into two classes with regard to their Lyt phenotype. First, are the cells that form the majority of the proliferating cells after restimulation with either I or K + I differences, which are Lyt 1-2-, and second, are Tc that are Lyt 1-2+. The Lyt 1-2- proliferating cells are not cytotoxic and are lysed by treatment with anti-Thy 1.2 serum in the presence of C.
