A novel drug target has been used to rescue functional deficits in human nerve cells derived from patients with Rett syndrome, a severe form of autism-spectrum disorder. The research could lead to a new treatment for Rett syndrome and other forms of autism-spectrum disorders, say investigators.

Mood-based disorders are one of the top-ten causes of disability worldwide. However the genes underpinning these disorders have proven to be remarkably elusive, say investigators. This study demonstrates that chickens are an excellent model organism for the genetic dissection of behavior.

An article published in the Neuron Journal about Mice with Shank3 Mutations Associated with ASD and Schizophrenia Display Both Shared and Distinct Defects highlighting (1) Major psychiatric disorders share many risk genes; (2) Two mouse lines with ASD-linked and schizophrenia-linked mutations were studied; (3) Two mutant lines show both shared and distinct synaptic and behavioral phenotypes, and (4) Both developmental and molecular differences were detected in the two mutant lines
