Among most miRs, miR155 has been used as a modulator for effectively restraining the TAMs-associated cytokine production via targeting C/EBPβ 175 and repolarizing immunosuppressive M2 type into immune-activated M1 type in vitro176, suggesting that increasing miR155 inside the TAMs holds a numerous promise in inducing M1 polarization and relieving tumor immune suppression for inhibiting tumor progression. Here, CEBPB is linked to neoplasm.
