Immune protein alters development in young mice

by  /  18 November 2010

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.

Molecular mechanisms: Maternal infection linked to schizophrenia in mice

by  /  9 November 2010

Infection early in pregnancy is more harmful to the fetus than at later stages, triggering brain and behavioral changes in the offspring similar to those seen in people with schizophrenia, according to two mouse studies published in October. A third study suggests that exercise can mitigate some of these effects.

Mother’s immune response alters brain structure

by  /  18 October 2010

Chemicals produced by their mother’s immune system in utero alter the size of several key brain regions in people with schizophrenia, enlarging chambers that store cerebrospinal fluids, and shrinking parts of the cortex involved in processing emotion and memory.

Flu triggers schizophrenia-like features in monkeys

by  /  25 June 2010

Babies born to rhesus monkeys infected with the flu virus during pregnancy have significantly smaller brains than normal, and other brain abnormalities seen in schizophrenia, researchers have found. The study, published last month in Biological Psychiatry, provides the first evidence in non-human primates linking flu infection to a higher risk of schizophrenia.
