G蛋白偶联受体C-C趋化因子受体5(CCR 5)作为HIV进入免疫细胞的辅助受体发挥作用。CCR 5与多种配体混杂结合,启动细胞信号传导,包括引导迁移。虽然众所周知在免疫细胞上表达,但最近的研究表明,乳腺癌上皮细胞表面的CCR 5的诱导。CCR 5对乳腺癌上皮细胞的功能包括诱导异常的细胞存活信号传导和对化学引诱剂的向性。由于CCR 5在正常上皮上不表达,因此该受体提供了潜在的有用的治疗靶点。CCR 5抑制剂(CCR 5i),无论是小分子(马拉韦罗,vicriviroc)还是人源化单克隆抗体(leronlimab),在临床前研究中都显示出抗肿瘤和抗转移特性。在早期的临床研究中,本文综述了CCR 5i对肿瘤和抗肿瘤免疫应答的影响,显示了有希望的结果和证据。因此,目前的临床研究包括与检查点抑制剂的联合治疗方法。
The G-protein-coupled receptor C-C chemokine receptor 5 (CCR5) functions as a co-receptor for the entry of HIV into immune cells. CCR5 binds promiscuously to a diverse array of ligands initiating cell signaling that includes guided migration. Although well known to be expressed on immune cells, recent studies have shown the induction of CCR5 on the surface of breast cancer epithelial cells. The function of CCR5 on breast cancer epithelial cells includes the induction of aberrant cell survival signaling and tropism towards chemo attractants. As CCR5 is not expressed on normal epithelium, the receptor provides a potential useful target for therapy. Inhibitors of CCR5 (CCR5i), either small molecules (maraviroc, vicriviroc) or humanized monoclonal antibodies (leronlimab) have shown anti-tumor and anti-metastatic properties in preclinical studies. In early clinical studies, reviewed herein, CCR5i have shown promising results and evidence for effects on both the tumor and the anti-tumor immune response. Current clinical studies have therefore included combination therapy approaches with checkpoint inhibitors.
