Kynurenines and cytokines were not analyzed in cerebrospinal fluid (CSF) of twins before. Psychotic symptoms and personality traits and kynurenic acid in CSF were associated. Correlations of tumor necrosis factor-α and interleukin-8 in CSF confirm in-vitro findings. Heritability may affect CSF-levels of kynurenic acid, tryptophan, interleukin 8 and tumor necrosis factor alpha.
