Immune gene tied to social behavior in autism mouse model

by  /  3 February 2022

Activating the immune system blunts social behavior in mice missing a copy of the autism-linked gene SHANK3, according to a new study. Blocking TRPV4, which encodes an ion channel involved in inflammatory responses, can reverse this effect.

Rethinking the origins of neurons: Q&A with Tomasz Nowakowski

by  /  20 January 2022

Excitatory and inhibitory neurons can derive from the same cellular source in the developing human brain, a new study suggests, overturning a 20-year-old hypothesis. Tomasz Nowakowski discusses the finding’s implications for autism research.
