Some genes linked to autism regulate the production of proteins at neuronal junctions, suggesting that disrupted protein synthesis contributes to the condition.

A trial of umbilical cord blood as a treatment for autism has passed a critical safety test, but many researchers remain skeptical of the approach.

A boost in the activity of microglia, the brain’s immune cells, during gestation may predispose boys to autism.

The brains of people with autism show a distinct molecular signature that reflects alterations in how genes are pieced together and expressed.

Peruse our picks for the best science photos published on Spectrum this year.

Our picks for the top 10 papers of the year highlight leaps in our understanding of autism, as well as lingering gaps.

Three studies suggest that microglia, the brain’s immune cells, join forces with neurons in a sex-specific manner.

A new method transforms lab-made stem cells into microglia, the brain’s immune cells.

Contrary to some previous reports, microglia may not play a central role in initiating Rett syndrome.

Genetic variants that impair a pathway that prunes neuronal connections may offer clues to autism.
