Despite flurry of findings, doubts dog gut microbes’ role in autism

by  /  19 October 2021

The possibility of microbial treatments for autism has inspired a burst of research and nascent clinical trials, but new research suggests these efforts rest on shaky scientific ground.

Precocious neurons may stunt brain growth in rare form of autism

by  /  5 October 2021

The first animal model of MYT1L syndrome suggests that fast-maturing neurons lead to the unusually small brains, social deficits and other traits seen in people with the condition.

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.

Drugs boost serotonin, socialization in multiple autism mouse models

by  /  6 August 2021

The finding that MDMA and an experimental serotonin agonist increase sociability across six different model mice suggests that disparate autism-linked mutations converge on the same underlying pathways.

Blocking key pathway reverses brain, behavior changes in autism mouse model

by  /  19 July 2021

Neurons in mice with an autism-linked mutation sprout extraneous protrusions, an overgrowth accompanied by above-average motor learning. Inhibiting a cell signaling pathway reverses the effect.
