摘要:: In this study, we have found that treatment of stimulator autologous adherent cells with anti-HLA-DQ mAb resulted in markedly enhanced proliferative response of T cells in human autologous mixed lymphocyte reaction system wherein T cells were cultured with autologous adherent cells at near ratio of adherent cells to T cells in peripheral blood, in which T cells minimally proliferate. However, treatment of stimulator-adherent cells with anti-HLA class I, anti-DR and anti-DP mAb had no effect on the proliferative response of T cells under the condition. It was further observed that CD4-enriched cells could significantly proliferate in the presence of autologous adherent cells either untreated or treated with anti-DQ mAb, although treatment of adherent cells with anti-DR mAb blocked proliferative response of CD4-enriched cells. Moreover, the proliferative response of CD4-enriched cells was suppressed by addition of CD8-enriched cells in the presence of untreated adherent cells, whereas the proliferative response of CD4-enriched cells could not be suppressed by CD8-enriched cells when the adherent cells in the culture were treated with anti-DQ mAb. These observations suggest that CD8 T cells are required for suppression of proliferative response of CD4 T cells to HLA-DR molecules on autologous stimulator-adherent cells, and that HLA-DQ molecules on the surface of adherent cells play an important role in the induction of suppression by CD8 T cells.
