The role of tumor necrosis factor (TNF)-alpha and its receptors in the pathogenesis of experimental autoimmune neuritis (EAN) induced by P0 peptide 180-199 in TNFR1 (p55) deficient (TNFR1-/-) mice was investigated. Compared to wild type EAN mice, TNFR1-/- EAN mice developed significantly more severe clinical signs, in parallel with enhanced numbers of inflammatory infiltrating cells in peripheral nerves and splenic P0-reactive T cell proliferation, as well as increased obviously MHC class II and CCR3 expression on the macrophages in the cauda equina. Our data indicated that TNF-alpha might have anti-inflammatory effect preventing the development of EAN in this mouse model.
研究了肿瘤坏死因子(TNF)-α及其受体在P0肽180-199诱导的实验性自身免疫性神经炎(EAN)发病机制中,在肿瘤坏死因子受体1(TNFR1,p55)缺陷(TNFR1-/-)小鼠中的作用。与野生型EAN小鼠相比,TNFR1-/- EAN小鼠出现明显更严重的临床症状,同时外周神经中炎性浸润细胞数量增加、脾脏P0反应性T细胞增殖增强,以及马尾巨噬细胞上MHC II类分子和CCR3表达明显增加。我们的数据表明,在该小鼠模型中,TNF-α可能具有抗炎作用,可预防EAN的发展。
