Further analysis revealed that macrophages expressing high levels of NT5E are characterized by elevated expression of chemokines and chemokine receptors such as CCR5, CCR2, ITGAV/ITGB5, and CSF1R, which may play a role in the recruitment of macrophages into the glioblastoma microenvironment [38]. Here, ITGB5 is linked to glioblastoma.
