Summary:Described herein is a novel polypeptide interaction trap assay which employs the use of prokaryotic host cells in producing fusion proteins which activate reporter genes. Central to the invention is a modified cyclosporin A and a modified, genetically engineered version of its receptor, cyclophilin. Methods are disclosed by which host-versus-graft disease following blood marrow transplantation is treated by transfected stem cells which are introduced into a patient such that modified cyclophilin is expressed and modified cyclosporin A is administered to the patient as necessary. The result is a method for inhibiting the proliferation of genetically engineered T cells comprising a nucleic acid encoding a mutated macrolide binding protein (MBP) selected from an FK506-binding protein (FKBP), cyclophilin, calcineurin, and FKBP:rapamycin associated protein (FRAP). Therapeutic applications emphasize intervention in host-versus-graft disease.
Abstract:This invention is directed to a modified cyclosporin A and to a modified, genetically engineered version of its receptor, cyclophilin. This invention is further directed to a method for treating host versus graft disease following blood marrow transplantation by transfecting stem cells so that after introduction into a patient the stem cells will express the modified cyclophilin, and, as necessary, administer the modified cyclosporin A to the patient.
