Solid organ transplants contain small numbers of leukocytes that can migrate into the host and establish long-lasting microchimerism. Although such microchimerism is often associated with graft acceptance and tolerance, it has been difficult to demonstrate a true causal link. Using skin from mutant mice deficient for leukocyte subsets, we found that donor T-cell chimerism is a 'double-edged sword' that can result in very different outcomes depending on the host's immunological maturity and the antigenic disparities involved. In immunologically mature hosts, chimerism resulted in immunity and stronger graft rejection. In immature hosts, it resulted in tolerance to the chimeric T cells, but not to graft antigens not expressed by the chimeric cells. Clinical efforts aimed at augmenting chimerism to induce tolerance must take into account the maturation state of host T cells, the type of chimerism produced by each organ and the antigenic disparities involved, lest the result be increased rejection rather than tolerance.
