Achieving the long-term goal of successful engraftment of retinal tissues into eyes blinded by endogenous retinal failure will depend, at least in part, on controlling the immune response to antigens expressed on retinal grafts. Since histoincompatible tissues will have to be used for such transplants, methods to control immune rejection directed at transplantation alloantigens must be devised. In addition, it has recently been observed in mice that developing neural retinal tissues express retina-specific antigens that have the potential to contribute to graft failure. To examine the potential risk of this contribution, syngeneic neonatal neural retinas were implanted into the anterior chamber, vitreous cavity, and subconjunctival space of adult BALB/c mice. During two weeks post-implantation, the fate of these grafts was observed clinically and histologically, and the retina-specific immune responses of the recipients were evaluated. Whereas grafts placed intraocularly thrived, carried out their inherent developmental potential, and were healthy and intact at the end of the observation interval. Grafts placed extraocularly expressed their differentiation program poorly. These grafts underwent rapid decline and attrition, although the process was not accompanied by significant inflammation. Recipients of subconjunctival, but not AC or VC, implants developed retina-specific delayed hypersensitivity. Alternatively, mice bearing AC and VC implants of neonatal neural retina developed retina-specific anterior chamber associated immune deviation. It is concluded that retinal autoantigens are expressed on developing neural retinal tissues and these antigens are highly immunogenic when retinal grafts are placed at conventional body sites. When similar grafts are placed in immune privileged compartments of the normal eye, they enjoy significant survival. Circumstantial evidence indicates that intraocular retinal grafts are protected and maintained in part by the emergence of systemic retinal auto-antigen-apecific immune suppression.
