A2M and glioma: Specific cell types, including glioma cells (PTPRZ1), oligodendrocytes (SEPT4, CNP, PLP1, and MBP), astrocytes (ID3, GFAP, AQP4, and SOX9), M1 macrophages (CD68, CD74, TSPO, and CD86), M2 macrophages (CD68, CD74, and CD163), T cells or natural killer (NK) cells (CXCR4 and S100A4), and endothelial cells (A2M and APOLD1), were found to have a correspondence with high expression of gene sets.
