Abstract: | The H-Y antigen has been studied under a variety of experimental conditions in BN and Lewis rats. The results indicate that 1. graft size is crucially important in determining the fate of male skin isografts on females; 2. H-Y incompatible ear skin grafts survive significantly better than those of trunk origin; 3. prior exposure of females to male lymphoid cells greatly increases their capacity to reject male skin isografts; 4. neonatal castration has no influence on the expression of H-Y; 5. multiparity can induce unresponsiveness to H-Y; and 6. although BN females respond better than do Lewis females to H-Y, the antigen is stronger in Lewis males. These findings are compared with the results of similar experiments conducted with mice.Submitted in memory of Dr. Joy Palm, member of the Wistar Institute, who pioneered the genetic analysis of histocompatibility in rats. |
