IRF4 deletion in T cells induces transplant tolerance in heart graft
recipients. Irf4fl/flCd4‐Cre
mice were transplanted with BALB/c hearts. Thirty days later, recipients were
transplanted again with BALB/c and C3H skins (n = 5). A, Schematic of the
experimental design. B, The percentage of skin allograft survival after skin
transplantation on BALB/c heart‐transplanted
Irf4fl/flCd4‐Cre
recipients. **P = .0079; Mann‐Whitney test. C,
