Abstract
Brain-derived neurotrophic factor (BDNF) and its high-affinity receptor, tropomyosin receptor kinase B (TrkB) signaling plays a key role in the brain neurodevelopment. The exposure of pregnant mice to polyinosinic–polycytidylic acid [poly(I:C)] causes cognitive deficits in adult offspring. Supplementation with a TrkB agonist, 7,8-dihydroxyflavone, in poly(I:C)-treated pregnant mice from pregnancy to weaning could prevent the onset of cognitive deficits and reduced BDNF–TrkB signaling in the prefrontal cortex of their adult offspring. These findings suggest that supplementation with a TrkB agonist in pregnant women with an ultra-high risk of psychosis may reduce the development of psychosis in their offspring.
