We also analyzed the differential expression of inflammatory genes in microglia (CD11b+/CD45low/Ly6c–/Ly6g– cells) and infiltrating monocytes (CD11b+/CD45+/Ly6c+/Ly6g– cells) isolated from the ILH and CLH of glioma-bearing mice. The gene discussed is PTPRC; the disease is central nervous system cancer.
