Blood-Brain Barrier Permeability Enhancement (BBB Permeability Enhancement)

Target: BBB Permeability Enhancement
Molecular classification: Physiological Process, Pharmacological Strategy

Overview

Blood-brain barrier (BBB) permeability enhancement refers to strategies and mechanisms aimed at increasing the passage of substances from the bloodstream into the brain. The BBB is a highly selective barrier, and enhancing its permeability is a critical target for improving drug delivery to treat neurological diseases. Strategies include modulation of tight junctions, targeting receptor-mediated transport pathways, inhibiting active efflux pumps, using cell-permeating peptides/nanoparticles, and hyperthermia techniques. Approaches must balance efficacy with safety due to risks associated with increased nonspecific entry into neural tissue.
