Potential benefits of ketone therapy as a novel immunometabolic treatment for schizophrenia.

Abstract

Therapeutic ketosis could target the potential bio-energetic pathophysiology of schizophrenia. Ideally, novel treatments also target the possible inflammatory aspects of schizophrenia. Adult mice (n = 30) were treated with ketone ester (KE) or vehicle for 3 days, next LPS- or PBS-injected. Brains were collected the next day. KE significantly attenuated the increased transcription of the pro-inflammatory cytokines Tnf-a, Il-6 and Il-1b, without affecting anti-inflammatory/immunomodulatory cytokines (Il-4, Il-10, Il-11) in whole brain. KE potently dampened neuro-inflammation in this acute inflammation mouse model. Ketone therapy could simultaneously target two possible pathophysiological pathways in schizophrenia. We encourage more research into the immunometabolic potential of therapeutic ketosis in schizophrenia.
