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.

Keep sex as a biological variable: Don’t let NIH upheaval turn back the clock on scientific rigor
Even in the absence of any formal instruction to do so, we should continue to hold our ourselves and our neuroscience colleagues accountable for SABV practices.

Single-cell genomics technologies and cell atlases have ushered in a new era of human neurobiology
Single-cell approaches are already shedding light on the human brain, identifying cell types that are most vulnerable in the early stages of Alzheimer’s disease, for example.
