IL4 and cancer: Accordingly, direct elimination of TAMs has been proposed as a promising strategy for cancer therapy.[7] Previous study have reported that BRD4 inhibition by JQ1 blocks the proliferation of TAMs.[10] To this end, M2‐like macrophages were induced by treating the Raw 264.7 cells with IL‐4, and further validated by the F4/80+ and CD206+ staining by FACS (Figure 4A,B).
