FGL2 and central nervous system cancer: To determine which cell type in glioma with high expression of FGL2 and FCGR3A, we summarized the analysis of the expression levels of FCGR3A and FGL2 in 17 glioma single-cell datasets in Supplementary Figure 6, and found that the expression level of FGL2 and FCGR3A are both highest in Mono/Macrophage across all datasets.
