  "account": "Phytometabolite-enriched edible plant-derived extracellular vesicles (PDEVs) demonstrate unique bioactive properties originating from their source, according to recent research. These nanocarriers, derived from sources such as black carrot, ginger, garlic, and turmeric, offer a promising biocompatible and orally deliverable delivery system for therapeutic purposes. However, certain aspects, including their phytometabolite cargo, gastrointestinal stability, and source-specific biological functions, have yet to be thoroughly investigated.\n\nTo address these gaps, researchers isolated PDEVs from the four distinct plant-based foods, chosen for their diverse bioactivity. The vesicles were characterized using transmission electron microscopy, nanoparticle tracking analysis, and zeta potential measurements. Additionally, gastrointestinal stability was assessed through a simulated digestion model. Source-specific phytometabolites were identified using untargeted LC-MS/MS metabolomics, and the vesicles were functionally tested in ammonia-stressed epithelial cells and steatotic hepatocytes.\n\nThe PDEVs displayed a characteristic cup-shaped morphology, with particle sizes ranging from 60 to 214 nm and zeta potentials between -6.0 and -49.0 mV. These vesicles exhibited excellent colloidal stability, indicating their suitability for oral delivery. By analyzing the vesicles, researchers identified 572 distinct phytometabolites, each with unique source-specific signatures. These metabolites included lignin and quercetin in carrot EVs, gingerol and silymarin in ginger EVs, diosgenin in garlic EVs, and curcumin in turmeric EVs. These metabolites were associated with various biological functions, including antioxidant and anti-inflammatory effects, maintenance of epithelial barrier integrity, lipid metabolism regulation, and apoptotic pathways.\n\nFunctional validation demonstrated that carrot EVs significantly enhanced epithelial barrier integrity, increasing claudin expression by a factor of 8 (p < 0.05) and up to 2 (p < 0.01) compared to controls. This finding highlights the potential of PDEVs as targeted drug delivery systems, taking advantage of the unique phytometabolites present in each source. Further investigation is needed to explore the therapeutic potential of these vesicles and their various phytometabolite cargo.",
