Naringenin ameliorates neuropsychiatric deficits in mice fed a methionine-choline-deficient diet.
📄 Abstract
Neuropsychiatric dysfunction is increasingly being acknowledged as a disabling complication of non-alcoholic steatohepatitis (NASH), but there are no therapeutic approaches. We investigated in the present study the neuroprotective effectiveness of naringenin, a citrus flavonoid with known anti-inflammatory and neurotrophic effects, in a murine NASH model induced by an 8-week methionine-choline-deficient (MCD) diet. Male C57BL/6 mice (n = 8/group) were treated with naringenin (50 mg/kg/day, i.p.) during the final 4 weeks. In behavioral tests, naringenin counteracted cognitive impairment in novel object recognition, reduced anxiety in both open field and elevated plus maze paradigms, and decreased immobility in the forced swim test, indicating antidepressant-like activity. Mechanistically, naringenin restored hippocampal apoptotic balance, normalizing the MCD diet-induced
