title: Two plasma membrane antigens of testicular sertoli cells and H-2-restricted versus unrestricted lysis by female T cells.
abstract: Sertoli cell-only seminiferous tubules of sterile XX,Sxrl-male mice served as an excellent source of pure Sertoli cells. When H-2-compatible female mice were immunized 3 times with these Sertoli cells, resulting antibodies recognized two antigens on the plasma membrane of testicular Sertoli cells. They were male-specific, but ubiquitously expressed H-Y antigen and the cell lineage-specific antigen which Sertoli cells shared with ovarian follicular cells. Doubly primed (2 or 3 times in vivo, and once in vitro) cytotoxic T cells from these females lysed target Sertoli cells in both H-2-restricted and nonrestricted manners. While H-2-restricted killings were attributable to H-Y antigen, further work is needed to identify the Sertoli follicular cell lineage-specific antigen as the cause of H-2-nonrestricted killings.
