Comparison of cytokine production between SC patients and healthy controls. IL-18 and IFN-γ release by non-stimulated and LPS-stimulated PBMC (pg/ml/106 cells) from 40 healthy controls (HC) and 51 schizophrenic (SC) patients. Supernatants were collected, stored at -80°C until analysis than measured for IL-18 and IFN-γ concentration using a commercial enzyme-linked immunosorbent assay (ELISA). All samples for a given assay were analyzed in duplicate at the same time. The ELISA values (in duplicates for each sample) have an error range lower than 10%. The variation coefficient of both inter-assay and intra-assay was <5%. Each data point represents the release of IL-18 and IFN-γ from each patient. Horizontal bars indicate group mean values.
