493-棒状杆菌脂质TMCM激活γδ T细胞增强眼部免疫防护

from 聊聊Sci

这份研究详细探讨了乳腺炎棒状杆菌(Corynebacterium mastitidis)如何通过分子机制增强眼部屏障免疫。研究者通过脂质组学和合成生物学手段,鉴定出一种名为单海藻糖分枝菌酸(TMCM)的特定微生物脂质,它是激发免疫反应的核心因子。该物质能同时激活抗原呈递细胞(如树突状细胞)以及特定的$γδ$ T细胞,进而诱导白细胞介素-17(IL-17)的产生。这种免疫机制能有效召集中性粒细胞并释放抗菌肽,从而保护眼睛免受铜绿假单胞菌等致病菌的感染。此外,TMCM展现出的免疫保护作用不仅局限于眼表,还延伸至皮肤及下游淋巴组织,凸显了其作为新型佐剂或治疗方案以强化屏障防御的巨大潜力。References: Xu X, Rigas Y E, Mattapallil M J, et al.
