Ly phenotype of cytotoxic T cells for syngeneic tumor.

Abstract
Present and previous findings may be summarized as follows. The phenotype of mouse C57BL/6 (B6) cytotoxic cells for allogeneic target cells is Thy-1+, Ly-1-, Ly-2/3+, MSLA+ and Ig-. The phenotype of B6 cytotoxic cells for syngeneic tumor cells is Thy-+, Ly-1+, Ly-2/3+, MSLA+ and Ig-. Differences in Ly phenotype appear to be exhibited by cytotoxic T [thymus-derived] cells as opposed to helper T cells, and within subcategories of cytotoxic T cells.
