摘要
CD96是一种免疫球蛋白超家族单次跨膜糖蛋白,主要表达于NK细胞和T细胞表面.研究表明,CD96-CD155轴可抑制Th9细胞的促炎效应,维持免疫平衡.小鼠肿瘤模型中,CD96-CD155轴抑制NK细胞和CD8+T细胞的抗肿瘤效应,CD96缺失或阻断可显著抑制肿瘤生长并延长荷瘤小鼠生存期,因此CD96被认为是一种潜在的免疫抑制分子(即免疫检查点).然而,关于人CD96功能的研究还处于起步阶段,尚未形成统一结论,尤其是阐明人CD96在肿瘤微环境中的作用机制研究十分缺乏,亟需深入探讨.本文主要从CD96的发现与沿革、分子结构、对炎症反应和肿瘤免疫的调节作用等方面进行综述.
Abstract
CD96 is a transmembrane glycoprotein belonging to immunoglobulin superfamily that mainly expresses on NK cells and T cells.Previous studies have shown that CD96-CD155 axis inhibits proinflammatory effects of Th9 cells to maintain immune homeostasis.In mice tumor models,CD96-CD155 axis suppresses anti-tumor effects of NK cells and CD8+T cells.CD96 deficiency or blockade significantly inhibits tumor growth and prolongs survival of tumor-bearing mice,thus CD96 is considered a potential immuno-suppressive molecule(i.e.immune checkpoint).However,research on human CD96 function is still unclear,with limited knowledge on role of human CD96 in tumor microenvironment,further in-depth exploration is needed.This review summarizes discovery and development,molecular structure,and regulatory roles of CD96 in inflammatory responses and tumor immunity.
