乳腺癌我的理解和你的不一样：

说的是表达ccr5的癌细胞，如果用CCR5 inhibitors，可纺织扩散。。。

ZT:

 The expression of CCR5 is selectively induced during the cancer transformation process and is not expressed in normal breast or prostate epithelial cells. Approximately 50% of human breast cancer expressed CCR5, primarily in triple negative breast cancer. ^[17]  CCR5 inhibitors blocked the migration and metastasis of CCR5 expressing breast and prostate cancer cells, suggesting CCR5 may function as a new therapeutic target. ^[17][18][19] Recent studies suggest that CCR5 is expressed in a subset of cancer cells with characteristics of cancer stem cells which are known to drive therapy resistance and CCR5 inhibitors enhanced cell killing of current chemotherapy.^[20] is likely that CCR5 plays a role in inflammatory responses to infection, though its exact role in normal immune function is unclear. Regions of this protein are also crucial for chemokine ligand binding, functional response of the receptor, and HIV co-receptor activity.^[21]
