Researchers at Johns Hopkins University published data suggesting that a panel of inflammatory proteins measured in blood may be useful in identifying changes that are characteristic of psychotic conditions. While more research is needed, these markers, including α2M, fibrinogen, IL-6R, SCF, TGFα, TNFR2, IL-8 and MCP-2/CCL8, have potential utility as early predictors of psychosis and raise questions about the role of infection in the pathology of schizophrenia.
