With the help of directed evolution, scientists inch closer to developing viral vectors that can cross the human blood-brain barrier to deliver gene therapy.

A state-of-the-art technique helps scientists map out tissue at the single cell level after a demyelinating brain injury.

Female postmortem brains contain more S-nitrosylated C3 proteins, likely linked to menopause, which instruct immune cells to kill neuronal synapses.

Genes activated in new environments include those used during development.

Haydeh Payami helped uncover the genetic basis of Parkinson’s disease. Now, she hopes to find new ways to treat the disease by studying the gut microbiome.

The mutation prevents certain amino acids from entering neurons, causing the cells to die early in development.

A study shows that a molecule produced by intestinal microbes can enter the brain and that its presence is also associated with altered brain connectivity.

Data from mouse models for mild coronavirus infections and human tissue samples offer further evidence that it doesn’t take a severe infection—or even infection of brain cells at all—to cause long-term neurological symptoms.

Experts say new research provides strong evidence that a common herpesvirus can trigger the chronic inflammatory disease.
