Blood vessels in the brains of more than half of autistic people have an unusually large number of T cells.

A set of neurons involved in complex cognitive functions may play a central role in autism.

Autism BrainNet, a repository of postmortem brains, has new tissue from more than 150 brains, including 59 from people with confirmed or possible autism.

A brain region that orchestrates responses to social cues and aids decision-making may be off tempo in autism.

The largest genetic analysis of postmortem brain tissue to date has yielded maps of when and where genes related to autism are turned on and off throughout life.

Specialized neurons called chandelier cells, which dampen brain signals, make unusually few connections in the brains of people with autism.

An unprecedented look at gene expression in tens of thousands of brain cells from autistic people suggests important roles in the condition for a neuronal subtype and for microglia.
