Tiny Trojan horse 'stealth' liposomes deliver drugs direct to brain injury sites

The blood-brain barrier (BBB) allows what is needed to nourish the brain and keeps out potentially dangerous, neurotoxic cells. When a person experiences traumatic brain injury (TBI) the BBB opens for a brief period of up to six hours after injury. Monash researchers have discovered that a small lipid sphere called a liposome - normally excluded from the brain - accumulates in the injured side of the brain during this window.
