Abstract

DBA/2 mastocytoma (P815) cells are able to grow when inoculated into the anterior chamber of eyes of histoincompatible mice. Tumor growth is unrestrained in recipient mice differing from the DBA/2 strain at multiple minor H loci, but sharing the H-2d haplotype; progressive tumor growth in these animals involves the entire eye, invades the orbit and kills the hosts by extension into the cranial vault. Alternatively, P815 cells grow initially but are unable to sustain continued growth in the anterior chambers of recipient mice differing from DBA/2 at the H-2 complex. Recipients differing from DBA/2 at either the K or D regions of H-2 develop anti-DBA/2 immunity that destroys the intraocular tumor within 20 days of inoculation. Severe inflammatory reactions in these eyes produce "innocent bystander" destruction of ocular tissue and produce blindness. Recipients differing from DBA/2 at both K and D regions of H-2 also mount vigorous anti-DBA/2 immunity that destroys the intraocular tumor. In these instances, the nonspecific component of the rejection reaction is minimal: when the tumor cells are destroyed, the eyes are restored to anatomic and functional integrity. These results indicate that immunologic privilege in the anterior chamber of the eye is afforded to allogeneic tissues to varing degrees depending upon allodisparity at H-2 loci encoding class I MHC products. The results further imply that the precision of the alloimmune response may be under the control of these same MHC products.
