Researchers discovered a novel link between immune system and social behavior

(University of Massachusetts Medical School) Using a systems-biology approach, scientists at the University of Massachusetts Medical School made a startling discovery that immune system signaling can directly affect, and even change, social behavior in mice and other model animals… [T]hese findings could have great implications for neurological diseases such as autism-spectrum disorders and schizophrenia…
The researchers note that a malfunctioning immune system may be responsible for "social deficits in numerous neurological and psychiatric disorders." But exactly what this might mean for autism and other specific conditions requires further investigation.
"For the first time we have a platform capable of systematically investigating the complex connections between immune signaling and various brain functions," [said Vladimir Litvak, PhD]. "I believe that anybody can use our technology as a template to investigate the involvement of various immune components in different brain dysfunctions."
