Furthermore, genetic or pharmacological blockade of TrkB has been shown to impede the growth of pediatric gliomas, as evidenced by increased survival rates in mice with brainstem NTRK2‐KO invasive pediatric glioblastoma or frontal cortex NTRK2‐KO pediatric cortical glioblastoma, compared to controls to wild‐type controls [44]. This evidence concerns the gene NTRK2 and glioblastoma.
