Blood-brain barrier
-
Research into a rare type of dementia has uncovered a genetic mutation that results in dysfunctional white blood cells and a breakdown of the blood-brain barrier, a mechanism that may play a role in common types of dementia such as Alzheimer's. -
A new particle that borrows chemical passports from neurotransmitters to slip through the blood-brain barrier could open up new avenues of treatment, with the technique showing promise as a way of tackling Alzheimer’s and other conditions.

The brain’s own defense mechanism often prevents treatment of brain cancers. But a new experimental treatment has shown success in mice, with carbon nanoparticles able to sneak through the blood-brain barrier and deliver drugs directly to tumors.
-
A new study from Northwestern University is demonstrating evidence a novel implantable ultrasound device allows a less toxic formulation of chemotherapy to cross the blood-brain barrier and destroy deadly tumors.
-
Two compelling new studies are building on a hypothesis suggesting age-related dementia is caused by a leaky blood-brain barrier. Experts suggest the studies are interesting but not particularly applicable to human cases of dementia.

The lamprey is not something you’d normally want anywhere near your brain. But now, researchers have used molecules taken from the freaky fish’s immune system to deliver drugs inside the body – and even managed to sneak them into the brain.

Building on recent research finding associations between a breakdown in the blood-brain barrier and the onset of cognitive impairment, a new study has homed in on a specific blood-clotting protein that can trigger synaptic damage after leaking into the brain.
-
New research has revealed an association between a breakdown of the blood-brain barrier and the onset of cognitive impairment. The study suggests leaky capillaries in the brain can act as an early biomarker of cognitive decline, and a new drug for stroke patients may be an effective treatment.

ScienceA new review article from a team at the University of Southern California is suggesting leaks in the blood-brain barrier could be a useful early warning sign signaling the onset of everything from Alzheimer's disease to multiple sclerosis before visible symptoms appear.

The blood-brain barrier is an effective shield against infection, but it’s not so helpful when you’re trying to get drugs in there. Nasal sprays could bypass the barrier, and now researchers have developed a way to use ultrasound pulses to drive the drugs to where in the brain they’re needed.

Scientists have successfully used the brains of locusts as a testbed for a new type of drug delivery system, one that could see life-saving medicines carried directly to the brain by way of a simple sniff.

A new type of engineered fat cell could make early-stage, difficult-to-detect brain tumors more treatable, by penetrating the blood-brain barrier and revealing their presence at a much earlier stage of development.
