Where this comes from

Abstract

Therapeutic delivery to the brain after stroke is limited by the blood-brain barrier. In this issue of Cell, Gao et al. bypass this obstacle by harnessing skull bone marrow immune cells to deliver drug-loaded nanoparticles to injured brain regions, improving outcomes and revealing a feasible translational strategy for targeted CNS therapy.
