Contrasting effects of B cell depletion on CD4⁺ and CD8⁺ memory T cell responses generated after transplantation.

ABSTRACT: Alloreactive memory T cells play a key role in transplantation by accelerating allograft rejection and preventing tolerance induction. Some studies using µMT mice, which are constitutionally devoid of B cells, showed that B cells were required for the generation of memory T cells after allotransplantation. However, whether B cell depletion in normal adult mice has the same effect on memory responses by CD4⁺ and CD8⁺ T cells activated after transplantation has not been thoroughly investigated. In this study, we tested the effect of anti-CD20 antibody-mediated B cell depletion on CD4⁺ and CD8⁺ memory T cell alloresponses after skin transplantation in wild-type mice. We found that B cell depletion prevented the development of memory alloresponses by
