10:58 AM | Psychiatric effects of childhood inflammation?
"Higher levels of the systemic inflammatory marker IL-6 [interleukin 6] in childhood are associated with an increased risk of developing depression and psychosis in young adulthood". So said the paper by Golam Khandaker and colleagues [1] looking at the growing link between inflammation and psychiatry.The bright light of Autumn @ Wikipedia The name Khandaker has appeared before on this blog (see here and see here), most recently with research looking at a possible link between […]

10:29 AM | Autoimmune disease risk and eating disorders
"We were set up. The cops were waiting for us.""We observed an association between eating disorders and several autoimmune diseases with different genetic backgrounds. Our findings support the link between immune-mediated mechanisms and development of eating disorders".So said the paper by Anu Raevuori and colleagues [1] (open-access) based on an analysis of over 2300 people "treated at the Eating Disorder Unit of Helsinki University Central Hospital between 1995 and 2010" compared with […]

8:42 AM | Omega-3 fatty acids rescues Fragile X phenotypes in Fmr1-Ko mice
"These results demonstrate that n-3 PUFAs dietary supplementation, although not a panacea, has a considerable therapeutic value for FXS [Fragile X syndrome] and potentially for ASD [autism spectrum disorder], suggesting a major mediating role of neuroinflammatory mechanisms".A view @ Wikipedia That was the conclusion reached by Susanna Pietropaolo and colleagues [1] who "evaluated the impact of n-3 PUFA dietary supplementation in a mouse model of fragile X syndrome […]

8:51 AM | Epigenetic processes and autism: focusing on immune function?
Although the title of this post talks about the science of epigenetics in autism, I'm actually going to be talking about two papers today, one of which also covers exposure to prenatal immune activation and what effect that might have on epigenetic processes in the mouse brain. This may also be relevant to at least some autism..."Beneath this mask there is an idea, Mr. Creedy. And ideas are bulletproof"First off we have the paper from Nardone and colleagues [1] (open-access) which, following […]
