New Nanovesicles from Prickly Pear Fruit Juice: A Resource with Antioxidant, Anti-Inflammatory, and Nutrigenomic Properties.

Plant-derived nanovesicles represent a novel approach in the field of plant-derived biomaterials, offering a sustainable and biocompatible option for various biomedical applications. The unique properties of these vesicles, such as their ability to encapsulate bioactive compounds, make them suitable for therapeutic, cosmetic, and nutraceutical purposes. In this study, we have, for the first time, successfully bio-fabricated vesicles derived from Opuntia ficus-indica (FicoVes) using an efficient and cost-effective method. Characterized by a size of approximately of 114 nm and a negative zeta potential of -20.9 mV, FicoVes exhibited excellent biocompatibility and hemocompatibility, showing no reduction in the viability of human and animal cells. Our results showed that FicoVes possess significant antioxidant properties as they reduced ROS generation in TBH-stimulated cells. FicoVes displayed anti-inflammatory properties by reducing the expression of pro-inflammatory cytokines (Il 1β, TNF α) and enhancing the expression of anti-inflammatory cytokines (IL4, IL10) following an inflammatory stimulus. Furthermore, FicoVes accelerated epithelial wound closure in L929 fibroblast monolayers in a dose-dependent manner, highlighting their potential role in tissue repair. This study establishes FicoVes as a promising candidate for nutrigenomic applications, particularly in the context of inflammation-related disorders and wound healing. Further research, including in vivo studies, is essential to validate these findings and fully explore their therapeutic potential.
