H-Y and antigens of the major histocompatibility complex. H-Y and H-2D antigens are associated on unfixed lymphocytes and thymocytes but not on testicular cells.
The results of an antibody blocking technique indicate that H-Y and H-2D antigens are close to one another on the surfaces of unfixed thymocytes and lymphocytes, but distant on testicular cells. The findings are the same using cells from mice of several inbred strains (C57BL/10, BALB/c, b6.H-2k). The data indicate moreover that H-2K antigens and H-Y are distant on all cell types tested. The gonad specific H-Y receptor-presumed necessary for H-Y directed testicular differentiation is associated with neither H-2D nor H-2K antigens.
