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.

Some social issues in DYRK1A model mice stem from faulty inhibitory circuits
Alterations in inhibitory circuits and difficulties in social recognition characterize mice missing one copy of DYRK1A, a gene linked to autism.

Mental health issues emerge with shifts in autism traits across childhood
Anxiety and other challenges autistic children experience may stem from an increase in social-communication issues and a decrease in repetitive behaviors from ages 6 to 11.

Neuronal deafness to stress may add to protein surplus in fragile X
A protective pathway that pauses protein synthesis is muted in a mouse model of fragile X syndrome, according to a new study.
