Abstract
AIM: To compare the mixed lymphocyte reactions (MLR) of human lymphocytes response to xenogenic murine lymphocytes and the allogenic human lymphocytes in vitro.
METHODS: Xeno-and allo- MLRs were set up and cellular classification study of xeno- and allo- MLRs were performed.
RESULTS: Human T cells response to xeno-cells was weaker than to allo-cells (P<0.05). Cellular classification study indicted that it was mainly CD4+ T cell involved in both allo- and xeno-MLRs, the former through direct and indirect pathways and the latter through indirect pathway. In addition, CD8+ T cell was involved in the reaction as well.
CONCLUSION: Xeno-MLR is weaker than allo-MLR. Xenogenic cells can only stimulate T cells through indirect pathway. Both MLRs share similar requirements for APCs, and human CD4 T cells are the major response cells.
