How star cells’ secretions may stunt neurons: Q&A with Nicola Allen

by  /  26 September 2022

Non-neuronal brain cells called astrocytes secrete proteins that seem to hamper the growth of neurons in people with autism-related syndromes. These proteins could be new drug targets, Allen says.

Largest-yet fragile X mutation in mice confirms model’s shortcomings

by  /  14 September 2022

A 341-repeat mutation from a person with fragile X does not lead to the syndrome’s traits or function the same way in mice, highlighting a need for different animal models.
