Clues that problems with mitochondria contribute to autism have been accumulating for decades. In the past five years, a mutant mouse and a flurry of findings have energized the field.
In this edition of Null and Noteworthy, tests of intranasal oxytocin and an Angelman syndrome treatment fail to see results.
Researchers are increasingly turning to simple animals to learn about autism biology and find leads for new drugs.
When Holly Stessman isn’t probing autism genes, she is tending to her flock of chickens or seeking out the next great sci-fi movie.
A mouse model hints that genes linked to inflammation in some women may increase the likelihood of autism in their children.
A genetic therapy and an existing drug both restore typical brain size in mice missing DYRK1A, a top autism candidate gene, in the cerebral cortex, a new study shows. The animals typically have smaller brains than controls.
A growing body of evidence shows that brain cells called oligodendrocytes may play a larger role in autism than previously thought.
Blood levels of PTEN protein and associated molecules could eventually help diagnose autism and other neurological conditions — and predict their outcomes.
A new tool enables researchers to create mosaic mutations in only some cells and then accurately identify which cells are affected.
Mice missing a copy of the autism-linked gene PTEN show a reduced preference for social interaction, possibly due to atypically large, overconnected dopamine neurons. Easing the overconnection may alleviate this trait.
