Patients with inflammatory bowel disease (IBD) have higher rates of psychiatric pathology, including anxiety and depression. The dextran sulfate sodium (DSS)-treated mouse is a well-characterized animal model of colitis that exhibits IBD-like and depressive-like changes. A recent study found that phosphorylated (p-) adenosine monophosphate-activated protein kinase (AMPK) was associated with anti-inflammatory and antidepressant effects. Our previous research in an animal model of major depression suggests that liver hydrolysate (LH) has an antidepressant effect and combats physical fatigue by enhancement via the hippocampal or peripheral p-AMPK pathway. In this study, we examined whether or not LH has antidepressant and anti-inflammatory effects in mice with DSS-induced changes. We evaluated colon inflammation in DSS-treated mice and used the tail suspension and forced swimming tests to confirm whether or not LH prevents IBD-like symptoms and depressive-like behavior. Hippocampal expression of AMPK, brain-derived neurotrophic factor (BDNF), doublecortin, and neuronal nuclear antigen proteins was assessed by Western blotting. Hippocampal neurogenesis and morphometric changes in the microglia and astrocytes were examined by immunohistochemistry. DSS-treated mice showed IBD-like pathology and depressive-like behavior, a reduction in the hippocampal neuronal nuclear antigen level and neurogenesis, and increased hippocampal activation of microglia and astrocytes. These changes were reversed by LH. DSS-treated mice showed enhanced hippocampal expression of p-AMPK and BDNF after administration of LH. LH prevented depressive-like behavior by enhancing hippocampal neurogenesis through the AMPK/BDNF pathway and anti-neuroinflammation in the hippocampus. LH may be a therapeutic option for patients with IBD and depression.
