Abstract: Antibody-mediated rejection (ABMR) is one of the main obstacles to successful transplantation, including ABO blood group-incompatible (ABOi) transplantation. C4d deposition is a marker of ABMR and is also found in most ABOi allograft tissues. Described herein are anti-C4d CAR Tregs that suppress ABMR in ABOi allografts. Anti-C4d CAR Tregs prepared by retroviral transduction of CAR into CD62L +CD4 +CD25 +Tregs, expressed Foxp3, CD25, CTLA-4, LAP, and GITR to similar extents as non-transduced Tregs. Anti-C4d CAR Tregs were activated by specific binding to C4d and suppressed in vitro T cell proliferation as well as non-transduced Tregs. Furthermore, adoptive transfer of anti-C4d CAR Tregs significantly prolonged mouse ABOi heart allograft survival (P<0.05).
