Finally, expression of these chemokines was investigated in human glioma cell lines, showing higher cytokine expression in the three patient‐derived IDH‐wildtype human glioma lines from three independent patients (U3039, U3046, and U3065) in comparison to a patient‐derived IDH‐mutant glioma cell line (TS603). This evidence concerns the gene IDH2 and central nervous system cancer.
