ITGB2,也称为整合素β2亚基,是一种重要的细胞表面受体蛋白,属于整合素家族。整合素是一种异源二聚体蛋白,由α和β亚基组成,负责介导细胞与细胞外基质(ECM)之间的相互作用,参与细胞粘附、迁移、增殖、凋亡等多种生物学过程。ITGB2亚基与αL亚基(CD11a)结合,形成整合素αLβ2(也称为LFA-1,淋巴细胞功能相关抗原1),主要表达于白细胞,特别是中性粒细胞和单核细胞,参与免疫细胞的活化、趋化和粘附过程。

ITGB2在多种疾病的发生发展中发挥重要作用。例如,在糖尿病肾病(DN)中,ITGB2表达上调,与肾功能恶化相关[1]。此外,ITGB2还与急性髓系白血病(AML)的预后相关,ITGB2高表达提示患者预后不良[2]。在动脉粥样硬化中,ITGB2作为中心枢纽基因,与炎症和早期纤维粥样斑块的发育相关,可能成为治疗的潜在靶点[3]。ITGB2基因突变与白细胞粘附缺陷1型(LAD1)相关,LAD1是一种原发性免疫缺陷病,患者表现为反复的细菌感染、伤口愈合不良等症状[4]。ITGB2还与慢性鼻窦炎伴鼻息肉(CRSwNP)的发生发展相关,可能作为M2巨噬细胞相关的生物标志物[5]。在非小细胞肺癌(NSCLC)中,ITGB2-AS1长非编码RNA通过抑制铁死亡,激活FOSL2/NAMPT轴,促进NSCLC对顺铂的耐药性[6]。ITGB2基因变异与早产儿坏死性小肠结肠炎(NEC)的易感性相关[7]。在脑缺血再灌注损伤(CIRI)中,Itgb2+小胶质细胞亚群在不同阶段表现出动态的功能变化,参与能量代谢、细胞周期、血管生成、神经元髓鞘形成和修复等过程[8]。在胶质母细胞瘤(GBM)中,ITGB2在肿瘤相关小胶质细胞(TAM)中高表达,通过激活ITGB2信号反馈,促进GBM细胞的间质转化[9]。在系统性红斑狼疮(SLE)和原发性干燥综合征(pSS)中,ITGB2表达上调,与IFN反应和ITGB2信号通路相关,可能成为治疗的新靶点[10]。

综上所述,ITGB2作为一种重要的细胞表面受体蛋白,在免疫细胞粘附、炎症反应、细胞迁移和增殖等过程中发挥重要作用。ITGB2与多种疾病的发生发展相关,包括糖尿病肾病、急性髓系白血病、动脉粥样硬化、白细胞粘附缺陷、慢性鼻窦炎伴鼻息肉、非小细胞肺癌、坏死性小肠结肠炎、脑缺血再灌注损伤和胶质母细胞瘤等。深入研究ITGB2的功能和作用机制,有助于揭示相关疾病的发病机制,为疾病的治疗和预防提供新的思路和策略。
