While glioma-infiltrating TAMs and microglia (termed glioma-associated microglia/macrophages [GAMs] as a group) have been identified in the past by the markers CD163, CD200, CD204, CD68, and Iba-1, the most common identification strategy in the literature considers microglia to be CD11bhighCD45low, while TAMs are CD11bhighCD45high [51]. Here, MSR1 is linked to glioma.
