Our brain is an extremely complex and delicate organ. Our body fiercely protects it by holding onto things that help it and keeping harmful things out, such as bugs that can cause infection and toxins ...

Researchers developed an innovative approach -- demonstrated in mouse models and isolated human brain tissue -- to safely and effectively deliver therapeutics into the brain, providing new ...

Exercise may sharpen the mind by repairing the brain’s protective shield. Researchers found that physical activity prompts the liver to release an enzyme that removes a harmful protein causing the ...

Scientists at the Icahn School of Medicine at Mount Sinai have developed a lipid nanoparticle system capable of delivering messenger RNA (mRNA) to the brain via intravenous injection, a challenge that ...

The cells that line the blood vessels in our brains are highly selective. By deciding which molecules are allowed in and out of our most important organ, the barrier these cells form is critical for ...

For every 1% increase in blood-brain barrier disruption, the odds of a person having a poor outcome 3 months after an ...

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). The research marks ...

Manganese is not a metal most people think much about. Unlike lead or mercury, it has a benign reputation. Small amounts of ...

Leakiness in the brain could explain the memory and concentration problems linked to long COVID. In patients with brain fog, MRI scans revealed signs of damaged blood vessels in their brains, ...
