Animal models of autism rooted in exposure to maternal antibodies hint at different mechanisms.

Mock viral infections impair social memory in mice with a mutation tied to autism, and autistic boys are more likely than their non-autistic peers to have had serious infections early in life.

A mouse model hints that genes linked to inflammation in some women may increase the likelihood of autism in their children.

The link between autism and prenatal exposure to an immune response may involve altered levels of immune cells, according to a new study.

An autism-linked mutation could make the brain grow unusually large by prompting cells to express a chemical signal better known for its connection to cancer.

Certain antibodies may shape neurodevelopment by attaching to and invading new neurons in the brain.

Too little — or too much — of certain substances during pregnancy may increase the odds of having a child with autism. Here we explain what scientists know about these associations.

A typically protective stress response could help to explain the connection between maternal illness and neurodevelopmental conditions.

Gene therapies and the factors influencing autism traits top Spectrum’s list of the 10 most notable research findings we covered in 2020.

An analysis of four molecular datasets shows a distinct signature, including changes in gene expression and chemical DNA modifications, in some autism brains.
