The gut mucosal epithelium is one of the largest organs in body and plays a critical role regulating crosstalk between resident microbiome host. To this effect, tight control what permitted through barrier high importance. There should be restricted passage harmful microorganisms antigens while at same time allowing absorption nutrients water. An increased permeability, or “leaky gut”, has been associated with variety diseases ranging from infections, metabolic diseases, inflammatory autoimmune to neurological conditions. Several factors can affect including cytokines, dietary components, microbiome. Here, we discuss how impacts permeability epithelial harnessed for therapeutic purposes.

A Comprehensive Review of the Triangular Relationship among Diet–Gut Microbiota–Inflammation

International Journal of Molecular Sciences, Год журнала: 2024, Номер 25(17), С. 9366 - 9366

Опубликована: Авг. 29, 2024

The human gastrointestinal tract hosts a complex and dynamic community of microorganisms known as the gut microbiota, which play pivotal role in numerous physiological processes, including digestion, metabolism, immune function. Recent research has highlighted significant impact diet on microbiota composition functionality, consequential effects host health. Concurrently, there is growing evidence linking to inflammation, key factor many chronic diseases such inflammatory bowel disease (IBD), obesity, diabetes, cardiovascular (CVDs). This review explores how dietary components influence composition, these microbial changes affect pathways, therapeutic implications modulating this axis for prevention management. Beneficial patterns, Mediterranean (MD) plant-based diets, promote diverse balanced supporting anti-inflammatory pathways. Conversely, Western (WD), high saturated fats refined sugars, associated with dysbiosis increased inflammation. With all links between three variables considered, attempts offer thorough examination triangle formed by food.

Platycodon grandiflorum-derived extracellular vesicles suppress triple-negative breast cancer growth by reversing the immunosuppressive tumor microenvironment and modulating the gut microbiota

Journal of Nanobiotechnology, Год журнала: 2025, Номер 23(1)

Опубликована: Фев. 7, 2025

Despite the approval of several artificial nanotherapeutics for treatment triple-negative breast cancer (TNBC), significant challenges, including unsatisfactory therapeutic outcomes, severe side effects, and high cost large-scale production, still restrict their long-term application. In contrast, plant-derived extracellular vesicles (PEVs) exhibit promising potential in therapy due to negligible systemic toxicity, bioavailability cost- effectiveness. this study, we developed an alternative strategy inhibit TNBC via Platycodon grandiflorum (PG)-derived (PGEVs). The PGEVs were isolated by ultracentrifugation sucrose gradient centrifugation method contained adequate functional components such as proteins, lipids, RNAs active molecules. exhibited remarkable stability, tolerating acidic digestion undergoing minimal changes simulated gastrointestinal fluid. They efficiently taken up tumor cells induced increased production reactive oxygen species (ROS), leading cell proliferation inhibition apoptosis, particularly line 4T1. Additionally, facilitated polarization tumor-associated macrophages (TAMs) toward M1 phenotype secretion pro-inflammatory cytokines. Further vivo investigations revealed that accumulated 4T1 tumors exerted effects through boosting anti-tumor immune responses modulating gut microbiota whether administered orally or intravenously (i.v.). conclusion, these findings highlight a natural, biocompatible efficient nanotherapeutic candidate treating TNBC.
