Abstract
Intestinal dysbiosis and the associated l-tryptophan metabolic disorder are pivotal in inflammatory bowel disease progression, leading to a compromised intestinal barrier integrity. Remedying the dysfunction in tryptophan metabolism has emerged as a promising therapeutic strategy. Herein, we reprogram the tryptophan metabolism in situ by EcN-TRP@A/G, encapsulating the engineered probiotic, EcN-TRP, with enhanced tryptophan synthesis capacity, for sustained modulation, thereby restoring intestinal barrier function and microbial homeostasis. The pH-responsive dual-layered EcN-TRP@A/G microcapsule developed via high-voltage electrospraying and liquid interface self-assembly, preserved probiotic viability in the harsh gastrointestinal milieu, and facilitated targeted colon release. Bioluminescent tracking in mice reveals a 22.84-fold increase in EcN-TRP@A/G viability and distribution compared to naked EcN-TRP. Targeted metabolomics highlights EcN-TRP@A/G's modulation of the tryptophan-indole pathway. Oral administration of EcN-TRP@A/G sustained elevates indole metabolites, particularly indole-3-acetic acid and indole-3-propionic acid, in colon tissue for up to 7 days. In IBD mice, EcN-TRP@A/G improves intestinal permeability, reduces inflammation, and recovers the gut microbiome by enhancing beneficial bacteria abundance like Prevotellaceae_UCG-001 and Anaerostipes while suppressing pathogenic strains like Escherichia-Shigella. Our findings offer a cost-effective approach, harnessing the probiotic metabolic potential in situ through engineered modifications for effective IBD treatment.

Abstract
Gut microbiota plays a crucial role in maintaining host homeostasis, impacting the progression and therapeutic outcomes of diseases, including inflammatory bowel disease, cancer, hepatic conditions, obesity, cardiovascular pathologies, and neurologic disorders, via immune, neural, and metabolic mechanisms. Hence, the gut microbiota is a promising target for disease therapy. The safety and precision of traditional microbiota regulation methods remain a challenge, which limits their widespread clinical application. This limitation has catalyzed a shift toward the development of multifunctional delivery systems that are predicated on microbiota modulation. Guided by bioinspired strategies, an extensive variety of naturally occurring materials and mechanisms have been emulated and harnessed for the construction of platforms aimed at the monitoring and modulation of gut microbiota. This review outlines the strategies and advantages of utilizing bioinspired principles in the design of gut microbiota intervention systems based on traditional regulation methods. Representative studies on the development of bioinspired therapeutic platforms are summarized, which are based on gut microbiota modulation to confer multiple pharmacological benefits for the synergistic management of diseases. The prospective avenues and inherent challenges associated with the adoption of bioinspired strategies in the refinement of gut microbiota modulation platforms are proposed to augment the efficacy of disease treatment.

Int J Nanomedicine 2024; 19:3611-3622. [PMID: 38660022 PMCID: PMC11041979 DOI: 10.2147/ijn.s456053] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2024] [Accepted: 04/14/2024] [Indexed: 04/26/2024] Open
Abstract
Background Mangiferin (MA), a bioactive C-glucosyl xanthone with a wide range of interesting therapeutic properties, has recently attracted considerable attention. However, its application in biomedicine is limited by poor solubility and bioavailability. Carbon dots (CDs), novel nanomaterials, have immense promise as carriers for improving the biopharmaceutical properties of active components because of their outstanding characteristics. Methods In this study, a novel water-soluble carbon dot (MC-CDs) was prepared for the first time from an aqueous extract of Moutan Cortex Carbonisata, and characterized by various spectroscopies, zeta potential and high-resolution transmission electron microscopy (HRTEM). The toxicity effect was investigated using the CCK-8 assay in vitro. In addition, the potential of MC-CDs as carriers for improving the pharmacokinetic parameters was evaluated in vivo. Results The results indicated that MC-CDs with a uniform spherical particle size of 1-5 nm were successfully prepared, which significantly increased the solubility of MA in water. The MC-CDs exhibited low toxicity in HT-22 cells. Most importantly, the MC-CDs effectively affected the pharmacokinetic parameters of MA in normal rats. UPLC-MS analysis indicated that the area under the maximum blood concentration of MA from mangiferin-MC-CDs (MA-MC-CDs) was 1.6-fold higher than that from the MA suspension liquid (MA control) after oral administration at a dose of 20 mg/kg. Conclusion Moutan Cortex-derived novel CDs exhibited superior performance in improving the solubility and bioavailability of MA. This study not only opens new possibilities for the future clinical application of MA but also provides evidence for the development of green biological carbon dots as a drug delivery system to improve the biopharmaceutical properties of insoluble drugs.
