title: Failure to alter neonatal transplantation tolerance by the injection of interleukin 2.
abstract: It has been postulated that the establishment of acquired, neonatal immunologic tolerance is due to a "deficit" in interleukin 2 (IL-2). To test this hypothesis, chickens were made immunologically tolerant to both major and minor histocompatibility antigens by transplantation of skin grafts onto newly hatched recipients. In this study, we injected various doses of IL-2 and concanavalin A simultaneously with transplantation and in some cases, several days posttransplantation, and we failed to enhance graft rejection. These results may have practical importance in respect to the clinical use of recombinant IL-2. Injection of IL-2 in and around surviving skin grafts also failed to alter skin graft survival.
