C1qb,也称为补体C1qB,是补体系统C1复合物的一个组成部分,该复合物在先天免疫反应中发挥关键作用。C1复合物由三个亚单位C1q、C1r和C1s组成,其中C1q又由C1qA、C1qB和C1qC三个亚单位组成。C1qB在C1复合物的形成和功能中起到重要作用,它能够识别并绑定到病原体表面上的免疫复合物,从而激活补体级联反应。C1复合物的激活最终导致病原体的溶解和清除。此外,C1复合物还能够促进炎症反应,通过释放炎症因子和招募免疫细胞来增强免疫应答。
C1qb基因的突变与多种疾病的发生和发展相关。例如,C1qb基因的某些多态性与精神分裂症的易感性相关。在亚美尼亚人群中,C1qb基因的rs291982*G等位基因与精神分裂症的发病风险增加相关[3]。此外,C1qb基因的表达异常还与多种癌症的发生和发展相关。例如,在皮肤黑色素瘤中,C1qb基因的高表达与较好的预后相关[4]。此外,C1qb基因的表达异常还与多种炎症性疾病的发生和发展相关。例如,在慢性鼻窦炎伴鼻息肉(CRSwNP)中,C1qb基因的表达异常与M2型巨噬细胞的浸润相关[1]。此外,C1qb基因的表达异常还与动脉粥样硬化的发生和发展相关。在动脉粥样硬化中,C1qb基因的表达异常与炎症反应和动脉粥样硬化斑块的形成相关[2]。此外,C1qb基因的表达异常还与糖尿病肾病的发生和发展相关。在糖尿病肾病中,C1qb基因的表达异常与细胞外基质重构和炎症反应相关[6]。此外,C1qb基因的表达异常还与非小细胞肺癌的发生和发展相关。在非小细胞肺癌中,C1qb基因的表达异常与预后相关[5]。此外,C1qb基因的表达异常还与前列腺癌的发生和发展相关。在前列腺癌中,C1qb基因的表达异常与免疫抑制性肿瘤微环境和疾病进展相关[7]。
综上所述,C1qb基因在多种疾病的发生和发展中发挥重要作用。C1qb基因的表达异常与多种疾病的发病风险、炎症反应、肿瘤微环境、细胞外基质重构和预后相关。深入研究C1qb基因的生物学功能和调控机制,有助于揭示疾病的发病机制,为疾病的诊断、治疗和预防提供新的思路和策略。
