PURPOSE:To carry out preliminary study on immunogenicity or'the retina and provide theoretical bassis of transplant rejection of the retina. METHODS:The allogeneic whole retinal or photoreceptor layer from C57BL/6 mice wer transplanted subcutaneously into BALB/C mice for antigen exposure and delayed hypersensitivity (DH) and modified 51Cr-release assay for specific cytotoxic T lymphoeytes (CTL)were emploied. RESULTS:The allogeneic whole retinal transplantation gave rise to DH(P lt;0.05 )and increased function of CTL of which the killing rate was 33.4% in concentration of 1:90 comparing with negative group (4.8% in 1:90,P lt;0.05)and the risen function could be blocked by anti-CD8. CONCLUSION:We deduce that allogeneic whole retina has immunogenicity and should pay attention to transplant rejection postoperatively.but the photoreceptor layer seems to have no immunogenicity and may be no transplant rejection after its transplantation. （Chin J Ocul Fundus Dis,1997,13: 234-236）
