VTCN1 and neoplasm: To evaluate the impact of B7x on the intratumoral composition of these subsets we assessed percentages and counted the absolute numbers of CD11c+ conventional dendritic cells (cDCs), CD11b+ GR1+ myeloid derived suppressor cells (MDSCs), CD11b+ F4-80+ CD206- M1 macrophages, and CD11b+ F4-80+ CD206+ M2 tumor associated macrophages (TAMs) and normalized these numbers by the tumor weight.
