Graft rejection

IL-7; IL-7 receptor (CD127)

Mouse studies suggest inhibiting IL-7 signaling could help prevent graft rejection. In a mouse model of diabetes, injection of an IL-7 receptor-blocking antibody starting 3 weeks before transplantation of pancreatic islets and continuing for 90 days post-transplantation increased graft survival and decreased formation and activation of donor-specific memory T cells compared with no treatment or with injection of the antibody at the time of transplantation. In a skin transplantation mouse model, IL-7 receptor blockade following T cell depletion prolonged graft survival to 58 days from 30 days. Next steps include testing safety and immunological features of an anti-human IL-7 receptor mAb in nonhuman primates.
