New gene variant may explain psychotic features in bipolar disorder
Researchers at Karolinska Institutet in Sweden have found an explanation for why the level of kynurenic acid (KYNA) is higher in the brains of people with schizophrenia or bipolar disease with psychosis. The study, which is published in the scientific periodical Molecular Psychiatry, identifies a gene variant associated with an increased production of KYNA. The discovery contributes to the further understanding of the link between inflammation and psychosis – and might pave the way for improved therapies.Kynurenic acid (KYNA) is a substance that affects several signalling pathways in the
