Loss of autism-linked gene alters synapse development in mice

by  /  25 January 2022

Mice missing a copy of the gene ASH1L have excess synapses and autism-like behavioral differences, some of which are reversed by boosting an ASH1L-regulated gene.

Growth factor analogue shows promise for Rett syndrome in late-stage trial

by  /  25 January 2022

Girls and young women with Rett syndrome have less severe anxiety and breathing problems after treatment with trofinetide, an analogue of insulin-like growth factor 1, according to an unpublished placebo-controlled trial.

Rethinking the origins of neurons: Q&A with Tomasz Nowakowski

by  /  20 January 2022

Excitatory and inhibitory neurons can derive from the same cellular source in the developing human brain, a new study suggests, overturning a 20-year-old hypothesis. Tomasz Nowakowski discusses the finding’s implications for autism research.

Infection in pregnant mice ups risk of gut problems in pups

by  /  18 January 2022

Infection during pregnancy can tweak a mouse’s gut microbiome in ways that have lasting effects on her pups’ immune system and increase their chances of gut inflammation, a new study suggests.

Neuron-specific virus overcomes barriers to brain-related gene therapy

by  /  14 January 2022

A new viral variant can deliver genes exclusively to the brain, overcoming a key hurdle in treating neurological conditions using gene therapy.

Autism-linked gene primes stress vulnerability in mice

by  /  3 January 2022

In mice with a mutated copy of SHANK3, stress induces social deficits and alters gene expression in certain excitatory neurons. But eliminating a stress-related protein that regulates SHANK3 restores typical social functioning in the animals.

Myelin loss may explain how autism-linked DNA deletion affects cognition

by  /  8 December 2021

Deleting a copy of the gene TBX1 depletes the fatty myelin insulation that surrounds neurons and reduces cognitive speed in mice.
