Glia Dysfunction in Schizophrenia: Evidence of Possible Therapeutic Effects of Nervonic Acid in a Preclinical Model

Neuroinflammation may inhibit oligodendrocyte and astrocyte differentiation, which causes demyelination and synaptic degeneration. The myelin component nervonic acid (NA) may improve demyelinating and neurodegenerative diseases. This study firstly explored relationships between glial cell dysfunction and demyelination or synaptic degeneration in schizophrenia patients, and secondly determined nervonic acid therapeutic effects in a preclinical schizophrenia model of mice. Plasma samples were collected from 18 male healthy controls and 18 male schizophrenic patients (diagnosed by DSM-V) at aged 18–55. Mouse brain samples were collected from a maternal immune activation (MIA) model of schizophrenia via injecting 5 mg/kg polyinosinic-polycytidylic acid. Male mouse offspring (age 2.5 months, n = 12) were treated by clozapine (15 mg/kg/day) or fed 0.5
