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.

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.

Neuronal deafness to stress may add to protein surplus in fragile X
A protective pathway that pauses protein synthesis is muted in a mouse model of fragile X syndrome, according to a new study.

Unknown isoform adds twist to theory of fragile X origins
Contrary to conventional wisdom, most people with fragile X syndrome express the FMR1 gene — albeit improperly.

New gene-editing method flags fragile X mutation for repair
The approach prompts cultured cells to correct the genetic mutation in fragile X syndrome using their own DNA repair system, but it still needs to be tested further.

Astrocytes fuel erratic firing in fragile X neurons
A shift in astrocyte secretions may explain the atypical firing patterns of neurons derived from people with fragile X syndrome.

Company on brink takes psilocybin to trial for fragile X syndrome
The phase 2A trial has its detractors despite positive animal results and is being sponsored by a company that is struggling financially.

Going on Trial: Orphan drugs; CBD; bumetanide
This month’s newsletter takes a close look at the orphan drug program in the United States, several cannabis-based therapies and a secondary analysis of bumetanide, among other new developments in autism-related drug trials.
Neurons struggle to spike without fragile X gene
FMR1 loss impairs sodium channels, hindering mouse neurons from generating the electrical signals needed to transmit information.

Missing mechanism helps solve fragile X protein mystery
Cells from people with fragile X syndrome overproduce — but don’t accumulate — proteins. New work suggests that excessive protein breakdown may account for this discrepancy, and explain some of the syndrome’s traits.

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.
