Molecular and biophysical remodeling of the blood–brain barrier in glioblastoma: mechanistic drivers of tumor–neurovascular crosstalk

Matthew Abikenari, Marcus Sjöholm, J. Liu, George Nageeb et autres

Glioblastoma (GBM) resists conventional treatment in large part because the blood–brain barrier (BBB) and its tumor-modified counterpart, the blood–tumor barrier (BTB), form a spatially heterogeneous, actively regulated interface that governs transport. In this setting, permeability, perfusion, and efflux are decoupled so radiographic …
