We next investigated if API induced changes at the tumor site and, for this reason, we used flow cytometry to examine MDSC subsets as well as M1-like TAM (CD11b+Ly6C+Ly6G−F4/80+CD206−CD86+) and M2-like TAM (CD11b+Ly6C+Ly6G−F4/80+CD86−CD206+) in the TME of OPC mice (see the flow cytometry gating strategy defined in Figure S3). The gene discussed is ITGAM; the disease is neoplasm.
