Mammalian exosomes have emerged as a promising class of functional materials, inspiring novel applications as therapeutic vehicles and nutraceutical compounds. Despite this, their immunogenicity has been an issue of controversy within the scientific community. Although, exosome-like vesicles, innately formed in plants and inherent to eukaryotic cell-derived vesicles, could soothe most of the concerns, they are notably underutilized as therapeutic modalities. This review highlights all efforts published so far, on the use of plant-derived extracellular vesicles (EVs) as therapeutic delivery systems. A summary of the physicochemical characteristics of plant-derived EVs is provided along with their main biological composition and in vitro/in vivo evidence of their therapeutic efficacy provided where available. Despite only a hand full of clinical trials being underway, concerning these vesicles, they arguably possess significant potential as nanodelivery systems of natural origin.

Conventional cancer treatments often induce a sustained DNA damage response (DDR) in tumor cells, leading to therapy-induced senescence (TIS), characterized by permanent cell cycle arrest and resistance to apoptosis. These senescent cells secrete senescence-associated secretory phenotypes (SASP), which can promote tumor progression and create an immunosuppressive microenvironment. This study introduces a novel approach to enhance chemotherapy efficacy by using functionalized curcuma-derived extracellular vesicles (DR5-CNV/DOX) to target and eliminate senescent tumor cells and inhibit their SASP.

Plant-derived foods are potential vehicles for microbial antibiotic resistance genes (ARGs), which can be transferred to the human microbiome if consumed raw or minimally processed. The aim of this study was to determine the prevalence and the amount of clinically relevant ARGs and mobile genetic elements (MGEs) in differently processed smoothies (freshly prepared, cold-pressed, pasteurized and high-pressure processed) and fresh produce samples (organically and conventionally cultivated) to assess potential health hazards associated with their consumption. The MGE and the class 1 integron-integrase gene were detected by probe-based qPCR in concentrations up to 10 copies/mL in all smoothies, lettuce, carrots and a single tomato sample.

Recent advancements in the field of plant-pathogen interactions have spotlighted the role of extracellular vesicles (EVs) as pivotal mediators of cross-kingdom communication, offering new vistas for enhancing crop protection strategies. EVs are instrumental in the transport of small regulatory RNAs (sRNAs) and other bioactive molecules across species boundaries, thus playing a critical role in the molecular warfare between plants and pathogens. This review elucidates the sophisticated mechanisms by which plants utilize EVs to dispatch sRNAs that silence pathogenic genes, fortifying defenses against microbial threats.

Stress protein HSP70 administered exogenously has demonstrated high potential as an efficient adjuvant in antitumor immune response. To enhance the antigen-presenting activity, bioavailability, and stability of exogenous recombinant human HSP70, we propose incorporating it into plant extracellular vesicles. Earlier, we found that grapefruit-derived extracellular vesicles (GEV) were able to store the protein with no loss of its major function, chaperone activity.
