GBP5,即鸟苷酸结合蛋白5,属于GTP酶亚家族,主要受干扰素γ(IFN-γ)的诱导,参与多种重要的细胞过程,包括炎症小体激活和先天免疫对各种微生物病原体的防御。GBP5在多种疾病中发挥着重要作用,包括炎症性皮肤病、骨关节炎、癌症和结核病等。
研究表明,GBP5在炎症性皮肤病中发挥重要作用。例如,GBP5通过促进M1巨噬细胞极化,加剧了类酒渣鼻样皮肤炎症[1]。GBP5在骨关节炎的进展中也发挥着重要作用。GBP5/IRF1轴通过激活软骨细胞焦亡,促进骨关节炎的进展[2]。GBP5在癌症的发生发展中发挥重要作用。GBP5通过激活Akt/mTOR信号轴和抑制自噬形成,增强紫杉醇对三阴性乳腺癌细胞的细胞毒性[3]。GBP5的表达水平与三阴性乳腺癌患者的预后密切相关,GBP5表达上调预示着患者对紫杉醇化疗的响应良好[3]。GBP5在三阴性乳腺癌中的表达水平与PD-L1的表达水平呈正相关,GBP5敲低可以抑制PD-L1的表达和细胞的迁移能力[6]。GBP5的表达水平与三阴性乳腺癌患者的脑转移间隔时间呈负相关[6]。GBP5在胶质母细胞瘤中高度表达,GBP5的表达水平与胶质母细胞瘤患者的预后密切相关,GBP5通过Src/ERK1/2/MMP3通路促进胶质母细胞瘤的恶性进展[4]。
GBP5在结核病的诊断中具有潜在的应用价值。GBP5蛋白水平在活动性结核病患者的全血中显著高于非结核病患者,GBP5蛋白水平可以作为活动性结核病诊断的潜在生物标志物[5]。GBP5在非小细胞肺癌中的表达水平与免疫相关基因的表达水平、肿瘤浸润淋巴细胞(TIIC)水平和PD-L1的表达水平呈正相关,GBP5可以作为预测非小细胞肺癌患者免疫治疗效果的潜在生物标志物[7]。
综上所述,GBP5在多种疾病中发挥着重要作用,包括炎症性皮肤病、骨关节炎、癌症和结核病等。GBP5的研究有助于深入理解GBP5在疾病发生发展中的作用机制,为疾病的治疗和预防提供新的思路和策略。
