CD68 and glioblastoma: Correlation analyses using GEPIA2 on GBM and LGG datasets have also been performed including the myeloid markers genes such as PTPRC (CD45), CD68, ITGAM (CD11b), CD14 and CD33 in order to evaluate the interactions between lymphocytes and myeloid cells in regulating the inflammation and tumor immunity in the glioma progression to glioblastoma.
