CD4+ Tregs specific for non-inherited maternal antigens (NIMAd) are detectable in some but not all B6 × BDF1 backcross, H-2b homozygous offspring, and their presence is strongly correlated with extent of maternal (BDF1) microchimerism. We hypothesized that the level of pre-transplant donor antigen-specific Tregs could predict allograft tolerance. To test this idea, mice were screened for bystander suppression in a DTH assay, followed 1 wk later by DBA/2 heterotopic heart transplantation. NIMAd-exposed, H-2b offspring that failed to suppress DTH uniformly rejected heart allografts (12/12) by d15. In contrast, 5/6 NIMAd-exposed DTH “regulators” accepted their allografts >100d. The defect in ‘non-regulator’ offspring could be corrected by transfer of CD4+CD25+, but not CD4+CD25neg or CD8+T cells from transplant acceptor mice. Donor-specific T reg screening of F1 backcross offspring correctly predicted which recipients would accept a heart allograft. If translated to the clinic, similar pre-transplant Treg screening could greatly enhance the effectiveness of tolerance as a clinical strategy in transplantation between family members.
