Cells drawn from a small sample of children with autism show defects in the functioning of their mitochondria — structures that produce energy to power cellular functions — according to a study published this week in the Journal of the American Medical Association.

Inhibiting the ERK1/2 pathway — which regulates the synthesis of other proteins — can rescue some of the effects of fragile X syndrome, according to a study published 17 November in the Journal of Neuroscience. The ERK pathway could provide a novel target for fragile X therapies.

Areas of the brain that are active when people are daydreaming or sleeping, and quiet when they are engaged in a task, are imperfectly synchronized in people with autism and attention deficit hyperactivity disorder, researchers say.

Minocycline, an antibiotic approved to treat various infections including acne, can increase vocalizations and provide long-lasting improvements in anxiety in a fragile X mouse model, according to two posters presented at the Society for Neuroscience annual meeting in San Diego.

Lowering the levels of proteins associated with Alzheimer’s disease can improve symptoms of fragile X syndrome in mice, according to a poster presented Wednesday at the Society for Neuroscience annual meeting in San Diego.

Sharing stories about his own family’s struggles with neurological disease, Patrick J. Kennedy, a Democratic Congressman, on Monday called for a focused national program to uncover the causes and treatments for brain disorders. The challenge today, he told SFARI, is to devote enough resources for research on disorders such as autism.

Ricardo Dolmetsch is making neurons from induced pluripotent stem cells derived from people with Timothy syndrome, a rare single-gene disorder that causes heart arrhythmias and autism. On Wednesday morning at the Society for Neuroscience annual meeting in San Diego, Dolmetsch talked to SFARI about how this approach could help autism research.

Pregnant mice injected with the immune protein interleukin-6 give birth to pups that are less social than normal, an effect that results from the over-activation of two pathways critical in neurodevelopment, researchers reported Tuesday at the Society for Neuroscience annual meeting in San Diego.

Lithium ameliorates some of the cognitive and behavioral deficits associated with fragile X syndrome by blocking GSK-3, an enzyme that plays a key role in development, researchers said Wednesday at the Society for Neuroscience annual meeting in San Diego.

Contrary to popular belief, receptors both outside and inside a cell regulate a cellular pathway that is overactive in people with fragile X syndrome, researchers reported Tuesday at the Society for Neuroscience annual meeting in San Diego. The finding could have significant implications for drug treatments of fragile X syndrome.
