Preimmunization of rabbits with chicken corneal extracts causes subsequent xenogenic corneal grafts to be rejected more violently and more rapidly than similar grafts in unmodified control animals. By definition, therefore, these extracts contain transplantation antigens. Immunization with these extracts also induces the formation of both precipitating and hemolyzing antibodies. Keratoplasty performed 6 weeks after immunization, when the antibody titers have declined measurably, produces an anamnestic precipitin response but fails to elicit a similar response for hemolysins. Evidence is presented indicating that in addition to transplantation antigens, the corneal extracts contain the Forssman antigen. The latter is responsible for the hemolysin response and has no relation to immunogenic rejection of the corneal graft. Author
