Ccr5抑制剂的代表药有哪些

Expression of CCR5 is induced in breast and prostate epithelial cells upon transformation. The induction of CCR5 expression promotes cellular invasion, migration, and metastasis. The induction of metastasis involves homing to the metastatic site. CCR5 inhibitors including maraviroc and leronlimab have been shown to block lung metastasis of human breast cancer cell lines. In preclinical studies of immune competent mice CCR5 inhibitors blocked metastasis to th… Webccr5是一種g蛋白偶聯受體，屬於整合型膜蛋白的β趨化因子受體家族成員 ，在cc趨化因子組中起趨化因子受體的作用 。 ccr5主要在t細胞，巨噬細胞，樹突細胞，嗜酸性球，小膠 …

WebMaraviroc is the first approved CCR5 antagonist (Fig. 130-6). HIV entry requires viral gp120 to sequentially bind CD4 and a surface co-receptor, either CCR5 or CXCR4. Maraviroc is an allosteric inhibitor of the gp120-CCR5 interaction that blocks HIV attachment to target cells and thereby reduces viral replication. Web该论文称，ccr5除了作为 hiv 病毒进入细胞的受体，还起到了抑制记忆和突触连接的作用，小鼠实验表明，敲除ccr5基因，不仅可以使小鼠更聪明，而且还能改善中风后的大脑恢复问题。但论文作者强调，敲除ccr5基因对人类的影响目前还无法预测。 mhy.fi https://adoptiondiscussions.com
