Given the unique anatomy and location of inflammatory bowel disease (IBD), oral pharmacological treatment is the mainstay for managing IBD because of its convenience and direct accessibility to the gastrointestinal tract. However, efficient delivery systems must be designed to navigate the harsh gastrointestinal environment during application. Here, an innovative oral drug delivery system was proposed using nanomotor (NM)-loaded soluble microcapsules for treating IBD. MnO 2 -Au-mSiO 2 NMs incorporate partially encapsulated MnO 2 antennas that convert reactive oxygen species into oxygen, autonomously propelling the NMs. Astaxanthin (AST), known for its anti-inflammatory properties, is loaded into the mesoporous silica (mSiO 2 ) of NMs (AST@NMs). AST effectively reduces inflammation and shifts macrophages from a proinflammatory (M1) phenotype to an anti-inflammatory (M2) phenotype. To protect the nanomotors from harsh digestive conditions and achieve intestinal-responsive release, using photocurable 3D printing, we fabricated enteric-coated oral microcapsules (MCs). Additionally, to prevent leakage of AST@NMs, a calcium alginate shell was cured in situ on the surface of the microcapsules (AST@NMs@MCs). In vitro and in vivo, AST@NMs@MCs effectively reduced inflammation, repaired the intestinal barrier, and modulated the gut microbiota. These findings underscore the protective effects of the microcapsules on AST@NM, highlighting their potential as a promising strategy for treating colitis.

Sulforaphane (SFN), a bioactive compound derived from cruciferous vegetables, exhibits chemopreventive properties agains various malignancies. Colitis-associated colorectal cancer (CAC) is a malignancy that develops through chronic inflammation-driven carcinogenesis in patients with long-standing inflammatory bowel disease. This study demonstrates a novel mechanism by which SFN protects against CAC through the simultaneous regulation of the Wnt/β-catenin signaling pathway and gut microbiota. Using an azoxymethane(AOM)/dextran sulfate salt sodium(DSS)-induced CAC mouse model to systematically evaluate SFN's therapeutic potential. Comprehensive assessments included histopathological examination, molecular analysis of inflammatory cytokines and proliferation markers, 16S rDNA sequencing for gut microbiota characterization, short-chain fatty acid (SCFA) profiling, and mechanistic investigation of Wnt/β-catenin pathway components. The experimental results showed that SFN intervention significantly alleviated clinical symptoms in mice, reduced inflammatory cytokine levels (IFN-γ, interferon-gamma; IHC, immune histochemical; IL-17, interleukin-17; IL-6, interleukin-6; MPO, myeloperoxidase) and suppressed proliferation markers (PCNA, proliferating cell nuclear antigen, antigen identified by monoclonal antibody Ki-67, Ki-67). Notably, SFN administration significantly restored the levels of major SCFAs, including acetate, propionate, and butyrate, which were markedly reduced in CAC mice. Mechanistically, SFN inhibited the Wnt/β-catenin signaling pathway by down-regulating the expression of β-catenin, cyclin D1 and c-myc expression. Concurrently, SFN restored gut microbial diversity, increased beneficial bacteria, and reduced pathogenic genera. The observed increase in SCFAs levels was correlated with these microbial improvements, and orrelation analysis further linked these microbial shifts to clinical improvements. Our findings reveal that SFN mitigates CAC progression by coordinated modulation of both Wnt/β-catenin signaling and gut microbiota, with the restoration of SCFAs production representing a key functional outcome, highlighting its potential as a multi-target dietary intervention for colorectal cancer prevention.

Egg yolk lipids significantly alleviate dextran sulfate sodium (DSS)-induced colitis by inhibiting NLRP3 inflammasome, reversing gut microbiota dysbiosis, and increasing short chain fatty acids (SCFAs) concentrations. However, the role of gut microbiota and the relationship between SCFAs and NLRP3 inflammasome are still unknown. Here, this study confirms that antibiotic treatment abolishes the protective effect of egg yolk lipids on DSS-induced colonic inflammation, intestinal barrier damage, and lipopolysaccharide translocation. Fecal microbiota transplantation also supports that egg yolk lipids alleviate colitis in a gut microbiota-dependent manner. Then, the study investigates the relationship between SCFAs and NLRP3 inflammasome, and finds that SCFAs significantly suppress colitis via inhibiting colonic NLRP3 inflammasome activation and proinflammatory cytokines secretions (interleukin, IL)-1β and IL-18, and combined treatment of SCFAs and MCC950 (NLRP3 inhibitor) shows a better activity against colitis and NLRP3 inflammasome activation. Together, these findings provide positive evidence for gut microbiorta-SCFAs-NLRP3 axis as a novel target involving in the therapy of inflammatory bowel disease.

Hydrogen sulfide (H 2 S) exhibits a Janus-faced nature in the regulation of inflammatory diseases, acting as both a therapeutic agent and a pathological aggravator. Effectively harnessing its beneficial effects while mitigating its harmful impacts is pivotal for advancing H 2 S-based therapies. Here, an innovative H 2 S supply system is introduced that enables H 2 S to primarily exhibit its therapeutic effects. Unlike conventional synthetic H 2 S donor-based strategies, a biomimetic H 2 S supply system (termed CP) is presented that mimics endogenous enzymatic H 2 S production. The CP sustainably produces H 2 S at a constant rate throughout the dosing period, ensuring therapeutic benefits while avoiding toxicity. Furthermore, by functionalizing CP with hyaluronic acid, the resulting system (CPH) not only achieves targeted delivery to inflammatory bowel disease (IBD) tissues but also provides controllable H 2 S production within the diseased microenvironment. Consequently, CPH significantly mitigates immune inflammation, promotes intestinal epithelial barrier repair, and modulates gut microbiota by sustainably and constantly supplying the multifunctional H 2 S. This study revolutionizes the H 2 S supply strategies and provides new insights into gas-based therapies.

Ulcerative colitis (UC) is a chronic bowel inflammatory disease affecting the colorectum. Epidermal growth factor (EGF) has been demonstrated to be effective to counteract UC. However, there exists the gastrointestinal challenges such as stomach acid, enzyme and bile salts for oral delivery of EGF. Herein, calcium alginate microsphere was prepared by the microfluidic technique to encapsulate EGF. The morphology of EGF-loaded microsphere (MS-EGF) was spherical and its average particle size was 80 ± 23 μm. The encapsulation efficiency of EGF was reaching to 93.8 % ± 1.6 %. In vitro release experiments showed that MS-EGF presented the good pH-sensitive properties, that was, it could effectively resist the gastric acid and small intestinal fluids, and undergone the rapid dissolution in the artificial colon fluid. In vitro cellular experiments demonstrated that the bioactivity of EGF was well preserved by microsphere. Moreover, in vivo murine colitis model showed that MS-EGF presented the obvious colitis alleviation. Furthermore, the colonic morphology of colitis mice was effectively recovered and the tight junction between the gut epithelium was obviously repaired. In conclusion, calcium alginate microsphere might be a promising vehicle of EGF for UC treatment.

Di-2-ethylhexyl phthalate (DEHP) is frequently used as a plasticizer to enhance the plasticity and durability of agricultural products, which pose adverse effects to human health and the environment. Aquaporin 1 (AQP1) is a main water transport channel protein and is involved in the maintenance of intestinal integrity. However, the impact of DEHP exposure on gut health and its potential mechanisms remain elusive. Here, we determined that DEHP exposure induced a compromised duodenum structure, which was concomitant with mitochondrial structural injury of epithelial cells. Importantly, DEHP exposure caused duodenum inflammatory epithelial cell damage and strong inflammatory response accompanied by activating the TLR4/MyD88/NF-κB signaling pathway. Mechanistically, DEHP exposure directly inhibits the expression of AQP1 and thus leads to an inflammatory response, ultimately disrupting duodenum integrity and barrier function. Collectively, our findings uncover the role of AQP1 in phthalate-induced intestinal disorders, and AQP1 could be a promising therapeutic approach for treating patients with intestinal disorders or inflammatory diseases.

Oral drug delivery systems had natural potential for colorectal cancer drug therapy. While the drug delivery efficiency is severely hindered by the complex intestinal barriers, especially mucus and epithelium barriers, resulting in unsatisfactory therapeutic effects and limited clinical translation. In this work, a bioactive self-thermophoretic and gas dual-driven nanomotor is developed for colorectal cancer therapy through efficient intestinal mucus and epithelial barrier penetration. The nanomotor shows intestinal mucus barrier penetration and the paracellular pathway reversibly opening properties of intestinal epithelium barrier, increasing the delivery efficiency of cisplatin by 3.5 folds. Owing to the targeted delivery of cisplatin and the reduced side effects on normal intestinal tissues, the therapeutic efficiency of the nanomotor for colorectal cancer in vivo is as high as 98.6%. With autonomous and reversible intestinal barriers penetration property, the nanoplatform may innovate the current oral drug delivery.

Microbiota dysfunction induces intestinal disorders and neurological diseases. Mannuronate oligosaccharides (MAOS), a kind of alginate oligosaccharide (AOS), specifically exert efficacy in shaping gut microbiota and relieving cognitive impairment. However, the key regulatory factors involved, such as the specific strains and metabolites as well as their regulatory mechanisms, remain unclear at present. This research investigates how MAOS specifically impact the gut–brain axis in vivo and in vitro. The results showed that pretreatment with MAOS significantly ameliorated dextran sodium sulfate (DSS)-induced colitis and secondary nerve injury. This preventive mechanism operates through the regulation of serum DOPC abundance and the gut–brain axis, achieved by inhibiting the TLR4/MyD88/NF-κB pathway. These findings underscore the crucial role of dietary MAOS in the prevention of colitis and neurological disorders, providing a rationale for the application of MAOS in disease prevention and functional food ingredients.

Introduction Anthocyanins have various health benefits but are limited by fast elimination and low bioavailability. Many studies have shown that nano delivery systems are effective in improving the intestinal absorption and bioavailability of anthocyanins. However, in the process of selecting anthocyanin nanomaterials, a dilemma is faced: numerous functional nanomaterials lack edible properties, it is difficult to meet the edible and functional requirements of nanomaterials simultaneously. Therefore, it is necessary and inevitable to select nano-anthocyanin carriers that are edible and have certain functional and morphological characteristics. Objectives We aim to provide an efficient, sustained-release and easy to industrialize nanosystem method to solve the problem of low bioavailability of anthocyanins. Methods A succinylated casein-phospholipid-anthocyanin nanosystem (CLS) was designed via computational chemistry-guided one-step self-assembly. Morphological, in vitro/in vivo digestion, pharmacokinetic were conducted. Furthermore, the effects of CLS on intestinal microecology were verified by using enteritis model animals, and the lung-targeting effect of CLS on lung health was verified by using lung injury model animals. Results CLS exhibited 24-hour intestinal sustained release and lung-targeted enrichment. Pharmacokinetic studies showed 25.7-fold higher lung AUC (0-t) and 13.1-fold higher blood AUC (0-t) compared to free anthocyanins. CLS significantly alleviated lung injury and colitis in model rats via the gut-lung axis. Conclusion This study significantly improved the bioavailability of anthocyanins and demonstrated the oral lung-targeting function of anthocyanins for the first time, paving the way for utilizing anthocyanins as dietary supplements and precision nutrition.

Colorectal cancer (CRC) is a worldwide health issue. It causes illness and death in millions of people each year. A positive correlation has been observed between the intake of dietary fat and the development of CRC. The composition of gut microbiota exhibits a significant correlation with pathophysiologic processes in intestine. Clinical treatment remains inadequate due to the complex pathogenic mechanisms of CRC triggered by a high-fat diet (HFD). Naringenin, a flavonoid from grapefruit, has anti-cancer activity. Our findings suggest that naringenin enhances gut microbiota diversity by increasing the abundance of beneficial bacterial species while reducing opportunistic pathogenic bacteria. The fecal microbiota transplantation assay (FMT) demonstrated that the anti-HFD-CRC activity of naringenin depended on the gut microbiota. Furthermore, naringenin antagonized the IL-6/STAT3 pathway. These results suggest that naringenin may be a potential treatment for HFD-CRC.

Constipation is a prevalent intestinal disorder that significantly diminishes patients' quality of life and predisposes them to various serious health conditions. Current therapeutic approaches for constipation frequently result in drug dependence and adverse effects. In this study, we present evidence that licorice water extract (LWE), a naturally derived compound from Glycyrrhiza uralensis Fisch, effectively ameliorates constipation in mice induced by diphenoxylate (DIP). Our findings indicate that oral administration of LWE (82 mg/kg/d) substantially reduces defecation time, enhances intestinal motility, and increases fecal water content in constipated mice. Furthermore, LWE elevates the levels of excitatory neurotransmitters such as serotonin (5-HT) and motilin (MTL), while concurrently decreasing the levels of inhibitory neurotransmitters including vasoactive intestinal peptide (VIP), nitric oxide (NO) as well as Lipopolysaccharide (LPS). Mechanistically, compared to the model control group, the LWE treatment upregulates the expression of ZO-1, Occludin , and MUC2 genes; repairs DIP-induced damage to the intestinal barrier; increases aquaporin 3 ( AQP3 ) protein expression; downregulates Toll-like receptor 4 ( TLR4 ); mitigates low-grade intestinal inflammation; and restores colonic goblet cell populations. Additionally, LWE is metabolized by gut microbiota, thereby restoring dysbiosis associated with DIP-induced constipation. In conclusion, our results suggest that LWE alleviates constipation through mechanisms involving intestinal barrier repair and gut microbiota modulation, highlighting its potential as an alternative therapeutic option for this condition. In response to this, we have developed a convenient gel-type candy (LWEI) with licorice extract and inulin as the main ingredients, which has shown good efficacy in relieving constipation.

Cadmium (Cd) is recognized as being linked to several liver diseases. Currently, due to the limited spectrum of drugs available for the treatment of Cd intoxication, developing and designing antidotes with superior detoxification capacity and revealing their underlying mechanisms remains a major challenge. Therefore, we developed the first next-generation probioticE. coli 1917-pSK18a-MT that delivers metallothionein (MT) to overcome Cd-induced liver injury in C57BL/6 mice by utilizing bacterial surface display technology. The results demonstrate thatE. coli 1917-pSK18a-MT could efficiently express MT without altering the growth and probiotic properties of the strain. Moreover, we found thatE. coli 1917-pSK18a-MT ameliorated Cd contamination-induced hepatic steatosis, inflammatory cell infiltration, and liver fibrosis by decreasing the expression of aminotransferases along with inflammatory factors. Activation of the Nrf2-Keap1 signaling pathway also further illustrated the hepatoprotective effects of the engineered bacteria. Finally, we showed thatE. coli 1917-pSK18a-MT improved the colonic barrier function impaired by Cd induction and ameliorated intestinal flora dysbiosis in Cd-poisoned mice by increasing the relative abundance of the Verrucomicrobiota. These data revealed that the combination ofE. coli 1917and MT both alleviated Cd-induced liver injury to a greater extent and restored the integrity of colonic epithelial tissues and bacterial dysbiosis.
