 虽然CD 40及其配体(CD 40 L)在体液免疫的发展中起着关键作用,但它们在细胞介导的免疫和细胞介导的自身免疫性疾病中的作用尚不明确。我们在这里报告,CD 40:CD 40 L相互作用是至关重要的实验性自身免疫性脑脊髓炎(EAE),一个原型TH 1细胞介导的自身免疫性疾病的发展。免疫时特异性阻断CD 40 L可显著抑制(PLJ×SJL)F1小鼠EAE的发病率、死亡率、发病日数和临床评分。重要的是,疾病抑制与自身反应性T细胞的无反应性或缺失无关,但伴随着其细胞因子谱的急剧改变。干扰素(IFN)-γ的产生受到明显抑制,而白细胞介素(IL)-4的产生则增强。这些结果表明,CD 40:CD 40 L相互作用在体内自身反应性TH 1与TH 2细胞的分化中起重要作用,并且CD 40 L阻断在预防自身免疫性脑脊髓炎中有效。
Abstract Although it is well established that CD40 and its ligand (CD40L) play pivotal roles in the development of humoral immunity, their roles in cell-mediated immunity and cell-mediated autoimmune diseases are not well defined. We report here that CD40:CD40L interaction is crucial for the development of experimental autoimmune encephalomyelitis (EAE), a prototype TH1-cell mediated autoimmune disease. Specific blockade of CD40L at the time of immunization markedly suppressed the incidence, mortality, day of onset, and clinical scores of EAE in (PLJ×SJL) F1 mice. Importantly, the disease suppression was not associated with anergy or deletion of autoreactive T cells but was accompanied by a drastic alteration of their cytokine profiles. The production of interferon (IFN)-γ was markedly suppressed while that of interleukin (IL)-4 enhanced. These results suggest that CD40:CD40L interaction plays important roles in the differentiation of autoreactive TH1 versus TH2 cells in vivo, and that CD40L blockade is effective in preventing autoimmune encephalomyelitis.
