Bioactive peptides have various excellent biological activities and serve as functional foods to prevent chronic diseases in the human body. This article investigated the regulatory effect of egg white peptides (EPs) on the intestine barrier of young mice with colitis. The results showed that the intake of EPs could protect the intestines from inflammation damage. Besides， the expression of tight junction (TJ) proteins and mucin is upregulated. Markedly， the intake of EPs can increase the concentration of amino acids in the serum of young mice， which is crucial for nutritional supplementation during intestinal inflammation process. Proteomics analysis implied that EPs can regulate protein expression in the intestine， involving multiple inflammatory pathways including PI3K-AKT and MAPK signaling pathway. This demonstrated the health benefits of bioactive peptides and provides a theoretical basis for the development of animal derived proteins as functional foods.

The anti-inflammatory properties of silkworm pupa peptide (SPP) have been recognized for their potential benefits in colitis treatment. However， the underlying mechanism of SPP in colitis animal models remains unclear. The objective of our work was to investigate the improving effect and the mechanism of action of SPP on a mouse model of dextrose sodium sulfate (DSS)-induced colitis. The findings suggested that SPP effectively eased ulcerative colitis (UC) symptoms in mice by decreasing disease activity index， ameliorating histopathological injury， and decreasing serum and colonic markers of inflammation. In addition， our research findings demonstrated that SPP restored intestinal barrier function by increasing the production of tight junction proteins such as zonula occludens-1 (ZO-1)， claudin-1， claudin-3， occludin， and adherens junction protein E-cadherin1. Further， SPP supplementation enhanced the concentration of short-chain fatty acids and positively altered the makeup of the gut bacteria in the mice’s gut. These findings underscore SPP’s ability to slow the progression of colitis and point to its possible use as a functional component in dietary supplements for the prevention of early-stage colitis.

The gut microbiota and it′s metabolism are vital targets of probiotics regulating high fat-diet (HFD) induced hyperlipidemia， which can relieve the pressure caused by the striking growth of sub-health people. Pediococcus pentosaceus PP04 (PP04) could colonize in intestine to regulate gut microbiota and it′s metabolites directly， the rebalanced intestinal flora mediated by PP04 could facilitate the secretion of short chain fatty acids to control body weight gain， PP04 intervention also changed bile acids (BAs) profiles and enhanced the ileal concentrations of antagonists including tauro-α/β-muricholic acid sodium salt and ursodeoxycholic acid to inhibit intestinal farnesoid X receptor/fibroblast growth factor 15 (FXR/FGF15) signaling coupled with the activation of hepatic FXR/small heterodimer partners signaling (SHP)， which accelerated the hepatic BAs de novo synthesis and excretion with feces to eliminate HFD caused hyperlipemia effectively. This study provided important evidence regarding PP04 as dietary supplement to relieve hyperlipidemia by influencing BAs enterohepatic circulation.

Background: Fructose may induce non-alcoholic fatty acids (NAFLD) due to the gut-liver axis interactions. The mechanism of fructose impairing colon barrier is unrevealed. Methods: Normal and DSS-induced Sprague-Dawley rats fed by 35% fructose diets were used to evaluate colon barrier functions. Microbiome and metabolome were applied to screen potential biomarker bacteria and metabolites induced by fructose. HT-29 cells were applied to validate metabolite biomarker indoleacrylic acid (IAA) and indole-3-carboxaldehyde (I3A) function in colon barrier which impaired by fructose. Results: Fructose induced colon barrier dysfunction， aggravated colon impairment in DSS-induced rats. With fructose intake， the colon length shortened， goblet numbers declined， inflammation infiltration induced， inflammatory cytokines increased， and apoptosis signals upregulated in colon tissue. Moreover， fructose induced dysbiosis of microbiota and their metabolites. Adlercreutzia， Holdemania were screened out as potential bacteria biomarkers， IAA and I3A as tryptophan metabolites were selected as metabolite biomarkers inhibited by fructose. IAA and I3A treatment alleviated the impairment induced by fructose by increasing trans epithelial electric resistance (TEER) value， tight junction proteins (TJPs)， and AhR activity in HT-29 cell. Conclusion: Fructose stimulated inflammation， apoptosis， gut bacteria alteration， and induced the reduction of IAA and I3A. Since fructose inhibited production of IAA and I3A， AhR remained inactivated and consequently induced colon barrier dysfunction.

In study， we investigated the effect of treatment with combination of < 3 kDa + Rg1 on scopolamine-induced cognitive impairment in mice and the mechanism of BDNF/TrKB/CREB signaling pathway in PC12 cells is regulated. In behavioral experiments， < 3 kDa+Rg1 treatment improved the memorizing ability of mice. Treatment with < 3 kDa+Rg1 significantly regulated the function of neurotransmitters and effectively improved the morphology of the neurons determined by H&E， Nissl， and Golgi staining. Additionally， immunohistochemistry showed that the < 3 kDa+Rg1 treatment significantly decreased AChE activity and increased ChAT content in the hippocampus. The treatment upregulated VAChT， activated the BDNF/TrKB/CREB signaling pathway， improved the remodeling of dendritic spines， and enhanced cholinergic functions. In the scopolamine-induced PC12 cells， combination treatment increased Trx-1 expression after administering TrKB and activated signaling pathway. The results showed combination of < 3 kDa+Rg1 activated the BDNF/TrKB/CREB signaling pathway by regulating function of neurotransmitters and enhanced cholinergic function to decrease cognitive impairment.
