IL4R and glioblastoma: Furthermore, although low level IL-2Rγ mRNA was also detected, no correlation between the expression of IL-2Rγ (common γ chain, γc) and either the expression of IL-13Rα1, or of IL-13Rα2 was detected, except week correlation with IL-4Rα expression in GBM (Supplementary Fig. S7a-c).
