Brain scans found an overactive immune system in patients as well as in those at high risk of schizophrenia.The UK Medical Research Council team wants to test anti-inflammatory drugs to treat or even prevent the disease.The researchers analysed microglia, which are the cells that protect the brain from infection and also "prune" unwanted connections between brain cells.
