本研究描述了T辅助细胞(Th)对同种异体和三硝基苯(TNP)修饰的自身I类主要组织相容性(MHC)决定因子启动原代细胞毒性T淋巴细胞(CTL)反应的特性。我们发现两种不同的Th细胞亚群参与异体特异性CTL反应:(a) L3T4+,Lyt-2- II类受限的Th细胞群,以及(b) L3T4-,Lyt-2+ I类受限的Th细胞群。这两种T细胞亚群通过与同种异体CTL前体的协同作用,在同种异体CTL反应中作为辅助细胞发挥作用。因此,初级I类异体特异性CTL反应不仅涉及L3T4+ Th细胞,还涉及Lyt-2+ Th细胞。L3T4+和Lyt-2+ Th细胞群在异位特异性CTL反应中发挥的必要功能之一是分泌白细胞介素2。最后,尽管抗allo和抗tnp - ctl反应有许多相似之处,但发现抗tnp - ctl反应仅由L3T4+ Th细胞介导,而不是由Lyt-2+ Th细胞介导。因此,Lyt-2+ Th细胞似乎是主要参与mhc特异性免疫反应的辅助细胞群。
This study characterizes the T helper (Th) cells that initiate primary cytotoxic T lymphocyte (CTL) responses against allogeneic and trinitrophenyl (TNP)-modified self class I major histocompatibility (MHC) determinants. We show that two distinct Th cell subsets participate in allospecific CTL responses: (a) an L3T4+,Lyt-2- class II- restricted Th cell population, and (b) an L3T4-,Lyt-2+ class I- restricted Th cell population. Both of these T cell subpopulations were shown to function in allospecific CTL responses as helper cells by their ability to show synergy with allospecific CTL precursors. Thus, primary class I allospecific CTL responses represent an immune response involving not only L3T4+ Th cells, but Lyt-2+ Th cells as well. One of the necessary functions performed by both L3T4+ and Lyt-2+ Th cell populations in allospecific CTL responses was found to be the secretion of interleukin 2. Finally, despite the many similarities between anti- allo- and anti-TNP-CTL responses, anti-TNP-CTL responses were found to be mediated by only L3T4+ Th cells, not by Lyt-2+ Th cells. Consequently, Lyt-2+ Th cells appear to be a helper cell population that is primarily involved in MHC-specific immune responses.
