CSF1R and glioblastoma: Finally, we analyzed the relationship between CSF1R/CSF1/IL34 expression and patient overall survival (OS), and the results showed that higher CSF1R/CSF1, as well as lower IL34 levels were significantly correlated to shorter OS in GBM patients (Fig. 1H and Supplementary Fig. 1A), supporting anti-CSF1R therapy in GBM.
