自身免疫性中枢神经系统(CNS)脱髓鞘疾病是一个主要的公共卫生负担,目前的免疫抑制剂控制不力。寻求具有更高功效和更少副作用的更精确的免疫疗法。我们研究了可注射的基于髓鞘的抗原性多聚蛋白MMPt(髓鞘少突胶质细胞糖蛋白,髓鞘碱性蛋白和蛋白脂质蛋白,截短)的有效性和机制。我们发现,它抑制小鼠实验性自身免疫性脑脊髓炎没有重大的副作用。MMPt诱导致脑炎性T细胞的快速凋亡并抑制受影响CNS中的炎症。活体显微镜检查显示MMP t被血管周围的F4/80+细胞摄取,但不被传统的抗原呈递树突状细胞、B细胞或小胶质细胞摄取。MMPt刺激的F4/80+细胞原位诱导反应性T细胞固定和凋亡,导致炎性细胞浸润和趋化因子产生减少。我们的研究揭示了解释同源抗原如何抑制CNS炎症的替代机制,并可能适用于有效和安全地治疗脱髓鞘疾病。抗原特异性T细胞耐受通过逆转CNS炎症改善小鼠自身免疫性脱髓鞘疾病
Autoimmune central nervous system (CNS) demyelinating diseases are a major public health burden and poorly controlled by current immunosuppressants. More precise immunotherapies with higher efficacy and fewer side effects are sought. We investigated the effectiveness and mechanism of an injectable myelin-based antigenic polyprotein MMPt (myelin oligodendrocyte glycoprotein, myelin basic protein and proteolipid protein, truncated). We find that it suppresses mouse experimental autoimmune encephalomyelitis without major side effects. MMPt induces rapid apoptosis of the encephalitogenic T cells and suppresses inflammation in the affected CNS. Intravital microscopy shows that MMPt is taken up by perivascular F4/80+ cells but not conventional antigen-presenting dendritic cells, B cells, or microglia. MMPt-stimulated F4/80+ cells induce reactive T cell immobilization and apoptosis in situ, resulting in reduced infiltration of inflammatory cells and chemokine production. Our study reveals alternative mechanisms that explain how cognate antigen suppresses CNS inflammation and may be applicable for effectively and safely treating demyelinating diseases. Antigen-specific T cell tolerance ameliorates autoimmune demyelinating diseases in mice via reversal of CNS inflammation.
