Heart anomalies abound in mouse models of autism

by  /  23 May 2022

Of nine genetic models examined in a new study, all had some incidence of cardiac abnormalities. But the problems varied widely depending on the affected genes.

Organoids show how mutations in top autism gene may lead to brain overgrowth in people

by  /  19 April 2022

The loss of CHD8, a top autism gene, speeds up the production of certain neurons and leads to overgrowth in spheres of cultured brain cells.

Three autism-linked genes converge on tweaks to cells’ timing

by  /  2 February 2022

Mutations in all three accelerate the maturation of inhibitory neurons, which could upset the brain’s balance of excitation and inhibition early in development.

Disruptions to brain’s ‘thermostat’ may underpin autism traits

by  /  18 August 2021

Mounting evidence suggests that autism often involves upsets in homeostatic plasticity, a set of processes neurons use to stabilize their activity. These disruptions result from a range of autism-linked mutations and may help to explain the condition’s famed heterogeneity.

Sleep problems in autism may stem from leaky brain barrier

by  /  23 July 2021

Problems with falling and staying asleep are common in autism, and they may be due in part to leaks in the blood-brain barrier, according to a new study in fruit flies.

Mapping the futures of autistic children

by  /  14 July 2021

Researchers can roughly project what autistic children’s lives will look like years down the road. But how good is their crystal ball — and what are its benefits?

Loss of top autism-linked gene from gut alters behavior in mice

by  /  4 May 2021

Deleting CHD8 from the intestines induces gastrointestinal and behavioral changes in mice that resemble traits in people with mutations in the gene.

Few autism researchers control for the ‘litter effect’ — this needs to change

by ,  /  27 April 2021

Anyone who uses multiple animals from a small number of litters to increase sample size is making a serious mistake. The similarities within individual litters will heavily skew the results.

Loss of CHD8 from cerebellum disrupts movements, not social behaviors

by  /  26 April 2021

Deleting the autism-linked gene CHD8 from specific cells in the cerebellum, a brain region important for movement, leads to motor deficits but does not alter social behaviors in mice.
