It has been known that CCL2 promotes PCa progression by way of recruitment of macrophages into the PCa microenvironment and IDO2 custom synthesis enhancing PCa cell growth and survival (Loberg et al, 2007). On the other hand, little is identified regarding the mechanisms linking androgen/AR suppression and CCL2 induction in PCa cells. Our present study very first established a previously unrecognized role of AR in negatively regulating CCL2 expression in PCa cells and TAMs, suggesting the present ADT only targeting androgen/ AR within the prostate tumour microenvironment might support to make an PI3Kδ Synonyms immunosuppressive tumour microenvironment by way of induction of CCL2, that is similar to wound healing research showing ARKO mice had an accelerated wound healing course of action (Lai et al.
