The enemy within
The possibility that autism is caused by a maternal immune system gone awry is no longer a fringe idea — but proposals to identify or fix these glitches are still controversial.

Maternal anti-brain antibodies may play a role in autism
Maternal antibodies that attack fetal brain proteins could underlie some cases of autism, says immunologist Betty Diamond.

Monkey mother’s immune response changes her infant’s brain
Monkeys whose mothers are infected with a mock virus while pregnant show abnormal branching of certain brain cells. The findings may help explain why infection during a woman’s pregnancy ups the risk of autism in her children.

Placenta plays potent role in autism risk
As the central organ regulating maternal-fetal interactions, the placenta is perfectly positioned to mediate environmental and genetic risk factors during prenatal development. It may also relay risk factors for autism to the fetus, says Paul Patterson.

Newborn blood may reveal early immune signs of autism
Children diagnosed with autism tend to have low blood levels of several immune molecules at birth, according to an epidemiological study published in August in the Journal of Immunology.

Study questions promise of bone marrow transplant for Rett
Researchers from four labs were unable to reproduce the findings from a high-profile 2012 study in which bone marrow transplants dramatically extended the lives of mice with features of Rett syndrome. Their sobering findings were published yesterday in Nature.

Cognition and behavior: Maternal infection linked to anxiety
Offspring born to pregnant rats with an activated immune system emit more distress calls when they receive electrical shocks than do controls, according to a study published 9 June in the Journal of Psychiatric Research.

Maternal infection exacerbates genes’ effect on autism
Children with too many or too few copies of certain genes are more likely to have autism, as are children born to women who battled a severe infection while pregnant. These seemingly disparate risk factors may work together to worsen autism symptoms.

Ketamine targets lateral habenula, setting off cascade of antidepressant effects
The drug’s affinity for overactive cells in the “anti-reward” region may help explain its rapid and long-lasting results.
