Abstract
IL-2-PE40 is a chimeric protein composed of human interleukin 2 (IL-2) genetically fused to the amino terminus of a modified form of Pseudomonas exotoxin lacking its cell recognition domain. IL-2-PE40, which is extremely cytotoxic to IL-2 receptor-positive cells, was examined for its ability to prevent graft rejection in mice in which activation of T cells is prominent. We demonstrate that intraperitoneally administered IL-2-PE40 specifically and significantly prolongs the survival of vascularized heart allografts in mice. The chimeric toxin, IL-2-PE40, offers an alternative approach to the treatment of autoimmune diseases and transplant rejection in humans.Entities:
