Plant Derived Exosome-Like Nanoparticles and Their Therapeutic Applications in Glucolipid Metabolism Diseases.

Plant derived exosome-like nanoparticles (PELNs) are membrane structures isolated from different plants, which encapsulate many active substances such as proteins, lipids, and nucleic acids, which exert a substantial influence on many physiological processes such as plant growth and development, self-defense, and tissue repair. Compared with synthetic nanoparticles and mammalian cell derived exosomes (MDEs), PELNs have lower toxicity and immunogenicity and possess excellent biocompatibility. The intrinsic properties of PELNs establish a robust basis for their applications in the therapeutic management of a diverse array of pathologies. It is worth mentioning that PELNs have good biological targeting, which promotes them to load and deliver drugs to specific tissues, offering a superior development pathway for the construction of a new drug delivery system (DDS). Glucose and lipid metabolism is a vital life process for the body's energy and material supply. The maintenance of homeostatic balance provides a fundamental basis for the body's ability to adjust to modifications in both its internal and external environment. Conversely, homeostatic imbalance can lead to a range of severe metabolic disorders. This work provides a comprehensive overview of the extraction and representation methods of PELNs, their transportation and storage characteristics, and their applications as therapeutic agents for direct treatment and as delivery vehicles to enhance nutrition and health. Additionally, it examines the therapeutic efficacy and practical applications of PELNs in addressing abnormalities in glucose and lipid metabolism. Finally, combined with the above contents, the paper summarizes and provides a conceptual framework for the better application of PELNs in clinical disease treatment.
