摘要 近10年来,天然免疫识别受体群的发现和肝脏免疫学的兴起,即发现肝脏天然杀伤(natural killer,NK)细胞和NK样T细胞(NKlike T cells,NKT)是其他器官含量的5~10倍,掀起了继20世纪70年代中期NK细胞发现之后的天然免疫研究的"第二次浪潮".天然免疫研究的这两个突出进展有可能重新解释某些肝脏疾病的免疫致病机理,也可能丰富天然免疫学的内涵.经过10年的研究,本研究小组发现,NK细胞和NKT细胞天然免疫识别介导了小鼠肝脏免疫损伤.我们通过Toll样受体3(Toll-like receptor-3,TLR-3)活化途径成功建立了NK细胞介导的小鼠自身免疫性肝炎模型,可模拟肝炎病毒携带者;观察到NK,NKT或枯否(Kupffer)细胞间的天然免疫调节网络参与肝脏免疫损伤,TLR-3活化枯否细胞可防止细菌毒素爆发性肝炎;TLR-3活化NK细胞可抑制由NKT细胞介导的致死性肝炎;乙型肝炎病毒(hepatitis B virus,HBV)转基因鼠肝脏易于免疫损伤与该鼠NK和NKT细胞NKG2D(natural killer cell group 2D)受体免疫识别异常有关;该鼠肝脏再生能力下降与NKT细胞过度免疫识别CD1d有关;阻断NKG2D或CD1d识别可缓解免疫性肝损伤.同时,对NK细胞调节性亚群(NK1,NK2,NK3,uNK细胞)进行了深入研究和发现内分泌激素瘦素(Leptin)和催乳素(Prolactin)可调控人类NK细胞分化;白细胞介素15(IL-15)通过抗凋亡促进人CD56dimNK亚群发育.
