Autism and fragile X feature immune signatures

by  /  30 March 2010

Scientists have identified distinct blood signatures of cytokines — proteins that control communication between cells of the immune system — in individuals with fragile X syndrome and autism.

Dog pedigrees unearth genes for psychiatric disease

by  /  22 February 2010

Researchers are using dogs as models of psychiatric and behavioral conditions, including obsessive-compulsive disorder and autism.

Variants in trust hormone receptor up the risk for autism

by  /  1 February 2010

Genetic variations that tweak the brain’s release of oxytocin — a hormone involved in social bonding and establishing trust — may increase the risk of developing autism or traits of the disorder, according to three new studies published in the past few months.

Guoping Feng: Unearthing the roots of compulsive behavior

by  /  4 January 2010

Guoping Feng’s perseverance has proven a boon to the hundreds of neuroscientists who rely on his most celebrated scientific achievement: two dozen mouse strains engineered to have brightly colored brain cells. By creating the first robust mouse model of obsessive-compulsive disorder, Feng has also found a way to study repetitive behaviors, one of the three core characteristics of autism.

Only subset of chromosome 16 variants linked to autism

by  /  20 November 2009

Deletions or duplications of chromosomal segment 16p11.2 — previously reported as a key autism region — are seen in people with developmental delays and speech and behavioral problems, but not necessarily autism. That’s the finding from two large studies published last week of people carrying these rare genetic variations.

Autism marked by altered trajectory of brain growth

by  /  3 November 2009

Although the head overall is bigger in some children with autism, researchers have found more informative differences in size — some smaller, some larger — across regions of the brain.

Antibodies to fetal proteins trigger autism features

by  /  21 October 2009

Antibodies directed against the fetal brain are present in some mothers of children with autism, confirming previous findings and suggesting that the antibodies could be used as a marker for the disorder, according to unpublished research presented yesterday at the Society for Neuroscience meeting in Chicago.

Therapies reverse autism in mouse model

by  /  19 October 2009

New pharmacological and behavioral interventions can reverse characteristics of autism in a mouse model of the disorder, according to unpublished results presented in poster sessions today at the Society for Neuroscience meeting.

Cancer pathway yields mouse model for autism

by  /  18 October 2009

Mice missing FKBP12, a gene involved in a cancer pathway, show repetitive behavior and an impaired ability to socialize with other mice, and could be used to study autism, according to unpublished results presented at a poster session today at the Society for Neuroscience meeting.

Study raises questions about autism-gut connection

by  /  18 August 2009

Children with autism are no more likely than healthy children to have some of the gastrointestinal symptoms — such as diarrhea, acid reflux and abdominal discomfort — previously tied to the disorder, according to one of the first long-term investigations of the supposed link.
