The blood–brain barrier is playing a critical role in controlling the influx and efflux of biological substances essential for the brain’s metabolic activity as well as neuronal function.

To recreate the barrier, the research team took those cell types that naturally make up the blood-brain barrier – microvascular endothelial cells, human astrocytes and human pericytes – and combined ...

By getting drugs beyond the blood-brain barrier, researchers believe they could better target treatment for Alzheimer’s disease, seizures, and plenty more. So, it’s safe to say it’s been a goal.

The blood-brain barrier is a protective layer that limits which molecules can access our gray matter. “That is very important to protect the brain, but also it makes it really hard when you do ...

Scientists have long struggled to define brain fog—let alone pinpoint a cause for it. But research is starting to reveal multiple potential causes from inflammation to a leaky blood-brain barrier.

The brain is among the most “immune-privileged” of organs primarily through the highly selective permeability of the blood-brain-barrier (BBB), its minimal lymphatic drainage, the presence of ...

Maybe the blood brain barrier disruption seen in some concussion patients applies to long COVID brain fog, too, the researchers surmised. Evidence for SARS-CoV-2’s damaging effects on the brain ...

Long Covid patients with brain fog all showed signs of a leaky blood-brain barrier, while long Covid patients without brain fog showed no signs of such an issue. Getty Images/iStockphoto.

This is also the first study that shows how quickly the blood-brain barrier closes after being opened by the ultrasound. It closes in the first 30 to 60 minutes after the communication. and this ...

The blood-brain barrier is a microscopic structure in blood vessels that connect to the brain and shield the critical organ from a vast majority of drugs and the movement of ions and molecules.

A new study published in the journal Nano Today reveals that nanoplastics, which are tiny plastic particles less than 1 micrometer in size, may cross the blood-brain barrier (BBB).
