CCR6,即C-C趋化因子受体6,是一种G蛋白偶联受体,属于趋化因子受体家族。它主要表达于T细胞,尤其是Th17细胞亚群,以及某些巨噬细胞和树突状细胞。CCR6与其配体CCL20(C-C趋化因子配体20)结合,参与免疫细胞的招募和迁移,在多种炎症和免疫反应中发挥重要作用。CCR6的激活可以引导免疫细胞到达炎症部位,参与免疫应答和疾病的进展。

根据所提供的参考文献,CCR6在多种疾病中发挥了重要作用。例如,在类风湿性关节炎(RA)患者中,CCR6和RORγt(视黄酸受体相关孤儿受体γt)的基因表达显著增加,且与疾病活动度和抗环瓜氨酸肽(anti-CCP)抗体水平呈正相关[1]。此外,CCR6还在结肠炎相关癌的发生发展中发挥作用,SMAD4基因的沉默导致CCL20和CCR6表达增加,从而促进炎症反应和肿瘤的发生[2]。在放射性皮炎中,CCR6也参与了炎症反应,其与IL-6/IL-1信号通路共同驱动了放射性皮炎的发生[3]。在前列腺癌骨转移中,CCR6的表达也显著升高,其与免疫抑制性微环境的形成有关,干扰CCR6/CCL20轴可以改善免疫抑制状态,延长生存时间[4]。在慢性胰腺炎中,CCR6和CCL20的相互作用也参与了免疫微环境的形成,CCR6+ Th细胞在遗传性慢性胰腺炎中显著富集[5]。此外,研究发现,饮食中的乳酸菌来源的胞外多糖可以诱导CCR6+ CD8+ T细胞的产生,从而增强免疫检查点阻断疗法的效果[6]。在肝细胞癌中,脂滴积累的巨噬细胞通过CCL20/CCR6轴促进了调节性T细胞的招募,进而抑制抗肿瘤免疫反应[7]。最后,在腰椎退行性疾病中,CCR6和IL-6基因表达与术后腰痛的强度相关[8]。

综上所述,CCR6在多种炎症和免疫反应中发挥重要作用,其表达异常与多种疾病的发生发展密切相关。CCR6及其配体CCL20的相互作用在免疫细胞招募、炎症反应和肿瘤发生中发挥着关键作用,是潜在的治疗靶点。
