NFIL3,也称为核因子IL-3调节因子,是一种转录因子,属于基本的螺旋-环-螺旋家族成员。NFIL3在细胞分化、发育、代谢和免疫调节中发挥着重要作用。NFIL3通过与DNA结合位点相互作用,调控目标基因的表达,影响细胞生物学过程。
NFIL3在多种疾病中发挥重要作用,包括癌症、自身免疫疾病和急性肾损伤。NFIL3的表达异常与多种癌症的发生和发展相关。例如,NFIL3在乳腺癌组织中表达升高,并通过抑制NFKBIA转录来激活NF-κB信号通路,促进乳腺癌细胞的增殖和转移[1]。NFIL3在多种癌症中也表现出化疗和免疫治疗的耐药性[2]。
NFIL3在自身免疫疾病中发挥免疫调节作用。例如,NFIL3在类风湿性关节炎(RA)患者的外周血和滑膜组织中表达升高,与炎症细胞因子和炎症反应相关,可能参与RA的进展[3]。NFIL3还参与调节Treg细胞的分化,影响免疫系统的平衡[7]。
NFIL3在急性肾损伤中发挥重要作用。例如,NFIL3在脓毒症相关急性肾损伤(SA-AKI)中表达升高,与铁死亡相关。NFIL3通过下调ACSL4表达,抑制铁死亡和炎症反应,保护SA-AKI[4]。
NFIL3在肝脏发育中也发挥重要作用。例如,NFIL3在猪肝脏中参与调节肝细胞代谢,影响肝脏的发育和功能[6]。
NFIL3在T细胞中也发挥重要作用。例如,NFIL3在CD8+ CTLs中控制细胞毒性机制,影响CTLs的细胞毒作用[5]。
综上所述,NFIL3是一种重要的转录因子,在细胞分化、发育、代谢和免疫调节中发挥着重要作用。NFIL3的表达异常与多种疾病的发生和发展相关,包括癌症、自身免疫疾病和急性肾损伤。NFIL3的研究有助于深入理解NFIL3的生物学功能和疾病发生机制,为疾病的治疗和预防提供新的思路和策略。
