However, little is known about whether N15 applies to other pathological or neuroinflammatory conditions. In the present study, we detected the effect of N15 on the LPS-induced neuroinflammatory response in mice and further investigated whether the effect of N15 on neuroinflammation and neuronal cells survival was related to PPARα/γ dual pathways. We found that N15 decreased the mRNA expression of the proinflammatory cytokines IL-1β, IL-6, TNFα, inducible nitric oxide synthase and cyclooxygenase-2; inhibited microglial activation; and ameliorated neuronal apoptosis in the hippocampus and cortex of LPS-induced mice. In addition, PPARα antagonist MK886 or PPARγ antagonist T0070907 partially eliminated the effect of N15. These results demonstrate that N15 exerts an anti-inflammatory effect, at least in part, by enhancing PPARα/γ dual signaling. Our study reveals that N15 may be a promising neuronal protective drug for the treatment of neuroinflammatory diseases.Eriodictyol, a natural flavonoid compound identified in numerous medicinal plants, has been reported to have anti-inflammatory, antioxidative and antiproliferative activities and exert protective effects on the neurons, thus drawing attention to its therapeutic potential. However, the effect of eriodictyol on depression remains unclear. In the present study, we investigated the behavioral effects of chronic eriodictyol treatment in rat models of depression induced by lipopolysaccharide (LPS, 1 mg/
