Ocular immune privilege
The eye attempts to limit local immune and inflammatory responses to preserve vision. This phenomenon, known as ocular immune privilege, is mediated by a combination of local and systemic mechanisms. While immune privilege is believed to protect the eye from day-to-day inflammatory insults, it is not absolute and its mechanisms are still incompletely understood.
متن کاملOcular Immune Privilege and Transplantation
Allografts are afforded a level of protection from rejection within immune-privileged tissues. Immune-privileged tissues involve mechanisms that suppress inflammation and promote immune tolerance. There are anatomical features, soluble factors, membrane-associated proteins, and alternative antigen-presenting cells (APC) that contribute to allograft survival in the immune-privileged tissue. This...
متن کاملOcular Immune Privilege and the Faustian Dilemma
JL he eye and the immune system represent discrete organ systems in vertebrates. Each possesses a unique and vital function that ensures the viability of the host, and loss of either or both brings disease and death. For many years, it has been known that the eye and the immune system are joined in a curious phenomenon called "immune privilege." This phenomenon was first described experimentall...
متن کاملEffects of experimental ocular inflammation on ocular immune privilege.
PURPOSE To determine whether the inflammation of endotoxin-induced uveitis (EIU) and experimental autoimmune uveoretinitis (EAU) alters key in vivo and in vitro parameters of ocular immune privilege. METHODS For EIU induction, C3H/HeN mice received 200 microg lipopolysaccharide (LPS). For EAU induction, B10.A mice were immunized with 50 microg interphotoreceptor retinoid-binding protein (IRBP...
متن کاملImmune Privilege
T he concept of immune privilege refers to the observation that tissue grafts placed in certain anatomical sites, including the brain and eye, can survive for extended periods of time (1). Immune privilege is thought to reflect an evolutionary adaptation to protect vital structures from damage by inflammatory responses directed against pathogens. It was originally believed that antigens in immu...
