Giant analysis reveals how autism-linked genes affect brain cell types
Genes that predispose people to autism account for a large portion of the neuronal and glial cell changes seen in those with the condition.

Where do cell states end and cell types begin?
High-throughput transcriptomics offers powerful new methods for defining different types of brain cells. But we need to think more explicitly about how we use these data to distinguish a cell’s permanent identity from its transient states.

Temperament is innate but hackable, animal studies suggest
Emotional reactivity and vulnerability to stress are largely inherited in rodents — but can be modified in early life by targeting inflammation-related cells or even just adjusting an animal’s environment.

Immune-activation model mice escape infantile amnesia, retain early memories
Male pups born to mothers treated with immune-stimulating molecules show autism-like behaviors and, unlike wildtype animals, do not lose memories formed during early life.

Serotonin powers pruning of developing brain circuits in mice
Mice with microglia missing receptors for the neurotransmitter serotonin since birth have too many synapses and show social difficulties in adulthood.
