Because the data suggested that microglial cells might be intimately involved in the pathogenesis of schizophrenia [60,61], we explored potential alterations in the pro- (MhcII, Cd40, iNos, Il-1β, Tnf-α and Il-6) and anti-inflammatory (Arg1, Igf-1, Tgf-β and Il-4) factors that are also considered microglial markers (Figure 9 and Figure 10). Here, IL1B is linked to schizophrenia.
