许多免疫反应的产生如混合淋巴细胞反应(MLR)、细胞毒T淋巴细胞(CTL)形成、过氧化物等诱导T淋巴细胞(TC)增生和依赖TC抗体的产生,都需要一种激活TC的细胞即免疫反应中的辅助细胞(Acc-essony-cell)参加,起刺激和抗原呈递作用.过去人们一般都认为这种辅助细胞是单核-Mφ.近几年对免疫反应中的一种新型辅助细胞-树状细胞(Dendritic cell,DC) The production of many immune responses such as mixed lymphocyte reaction (MLR), cytotoxic T lymphocyte (CTL) formation, peroxide induced T lymphocyte (TC) hyperplasia, and TC-dependent antibody production all require an activation of TC Cells, the immune response of the helper cells (Acc-essony-cell) to participate in the role of stimuli and antigen presentation in the past people are generally considered to be mononuclear-Mφ. In recent years, a new type of immune response Auxiliary cells - Dendritic cells (DCs)
