- Memory cells are currently thought to be a major barrier to tolerance induction in transplantation. However, whether alloreactive memory cells resulting from a primary transplant have cross-reactivity in a second transplant is unclear. Here, we used skin transplantation from BALB/c mice donors to pre-sensitize C(57) BL/6 (B6) mice. One month later, several strains of mice (including BALB/c, DBA/2, NOD, C3H and B6 mice) were chosen as donors to construct a memory model of heterotopic cardiac transplantation.

The varying degrees of MHC mismatch between the primary and secondary donors influenced the intensity of alloreactive memory cell function, the higher degree of MHC mismatch resulted in better tolerance during secondary transplantation, and these may be related to the changed activation, proliferation and function of the alloreactive memory cells.
