Microglial overreaction to atypical neurons may drive autism
In mice and organoids lacking a neuronal protein, microglia prune synapses to excess.

Synaptic protein’s shape-shifting skills propel plasticity
SYNGAP supports learning without tapping its eponymous “GAP” enzymatic activity, according to a new study.

Autism-linked perturbations converge on cell skeleton and RNA-binding proteins
The findings solidify the idea that autism-linked mutations affect brain activity by way of several key shared mechanisms.

What goes up must come down: New marker flags decreased neural activity
Phosphorylation of the metabolic enzyme pyruvate dehydrogenase inversely correlates with neural activity, offering scientists a tool to study inhibition for the first time.

Top autism-linked genes join forces to shape synaptic plasticity
The protein products of ANK2 and SCN2A interact to regulate dendritic excitability.

Noisy brain may underlie some of autism’s sensory features
Random fluctuations in neuronal activity are more variable in a fragile X mouse model than in wildtype mice.

Immune-activation model mice escape infantile amnesia, retain early memories
Male pups born to mothers treated with immune-stimulating molecules show autism-like behaviors and, unlike wildtype animals, do not lose memories formed during early life.

Going deep: The Transmitter’s top long-form stories in 2023
Our favorite features and book excerpts from the past year delved into the neurobiology of cancer; problems with survey data; free will; mathematical minds; and questions around one startup’s quest to treat brain conditions with cell therapies.

Making cancer nervous
Nerve cells in the brain and throughout the body can turbocharge tumor growth — a finding that not only expands conventional ideas about the nervous system but points to novel therapeutic targets for a range of malignancies.
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.

Some minimally verbal autistic people show signs of written-language familiarity, study suggests
But researchers not involved in the work worry the findings could be used to support discredited facilitated-communication techniques.

Cocaine, morphine commandeer neurons normally activated by food, water in mice
Confirming a long-held hypothesis, repeated exposure to the drugs alters neurons in the nucleus accumbens, the brain’s reward center, and curbs an animal’s urge for sustenance.
