New tool may help untangle downstream effects of autism-linked genes
The statistical approach helps scientists better control for both measured and unmeasured confounders in gene-expression data, revealing causal relationships between autism-linked genetic variants and downstream cellular effects, such as impaired neuron development.

Familiar autism-linked genes emerge from first analysis of Latin American cohort
The findings, detailed in a January preprint, suggest autism’s fundamental biology is the same regardless of ancestry. But questions remain.

Protein aggregates gum up ‘master regulator’ of autism-linked genes
The regulator, CPEB4, typically controls protein production for hundreds of autism-linked genes, but an alternative version of it found in autistic people forms irreversible clumps and malfunctions.

Mutation in top autism-linked gene may alter eye reflex
The discovery could help clinicians diagnose children who carry mutations in the gene, called SCN2A, and gauge their responses to potential therapies.

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.

UBE3A’s link to synaptic pruning bolstered by fly study
Increasing or reducing the levels of the UBE3A gene, which is associated with autism and autism-related syndromes, results in altered patterns of synaptic pruning — a process that snips away brain cell connections.

Head size parts autism into two major subtypes
An imbalance in the number of excitatory neurons in early brain development may account for the difference.

Skewed signaling in striatum may spawn repetitive behaviors
Synaptic changes in the brain region could drive a core trait of fragile X syndrome, a new mouse study suggests.

Father’s genes may drive sociability in male monkeys
The findings in rhesus macaque monkeys may provide clues to sex differences in the heredity of social behavior in people.

New test taps nose pokes as a proxy for social motivation in mice
Over one hour, a particularly motivated mouse poked its nose 350 times into a hole in the test chamber in the hopes of meeting a playmate.

Null and Noteworthy: Neurons tracking sequences don’t fire in order
Instead, neurons encode the position of sequential items in working memory based on when they fire during ongoing brain wave oscillations—a finding that challenges a long-standing theory.

How to teach this paper: ‘Neurotoxic reactive astrocytes are induced by activated microglia,’ by Liddelow et al. (2017)
Shane Liddelow and his collaborators identified the factors that transform astrocytes from their helpful to harmful form. Their work is a great choice if you want to teach students about glial cell types, cell culture, gene expression or protein measurement.

Astrocytes sense neuromodulators to orchestrate neuronal activity and shape behavior
Astrocytes serve as crucial mediators of neuromodulatory processes previously attributed to direct communication between neurons, four new studies show.
