Abstract
BACKGROUND Aloe vera (AV) is a medicinal plant, most known for its beneficial effects on a variety of skin conditions. Its known active compounds include carbohydrates and flavonoids such as quercetin and kaempferol, among others. In the past decade, plant nanovesicles (NVs) have gained considerable interest as interkingdom communicators, presenting an opportunity for clinical standardization of natural products. In this study, we aimed to assess the potential of AVpNVs for the treatment of burn wounds. METHODS AVpNVs were isolated and characterized regarding vesicle yield (nanoparticle tracking analysis) and structure (transmission electron microscopy and atomic force microscopy), as well as their protein content with proteomics. We assessed key characteristics for treating burn wounds in vitro, such as the anti-inflammatory potential in LPS-stimulated macrophages and keratinocytes, and the effect of AVpNVs on myofibroblast differentiation and contraction. KEY FINDINGS AVpNVs presented a homogenous NV population, vesicular shape, and NV-associated protein markers. AVpNVs significantly decreased the secretion of pro-inflammatory cytokines TNFα, IL-1β, and IL-6. Furthermore, AVpNVs inhibited myofibroblast differentiation and significantly decreased their contractile potential in collagen matrices. Observed effects were linked to proteins identified in the isolates through proteomics analysis. CONCLUSION AVpNVs displayed characteristics as an inflammatory modulator, while simultaneously diminishing myofibroblast differentiation and contraction. Novel strategies for burn wound treatment seek to decrease scarring on a cellular and molecular level in the early stages of wound healing, which makes AVpNVs a promising candidate for future plant-vesicle-based treatments.

Abstract
The plant extracellular vesicles (EVs) are lipid-enveloped nano-particles containing proteins, nucleic acids and metabolites and function in plant development and response. The Arabidopsis four transmembrane protein TETRASPANIN 8 (TET8) knock-out mutant tet8 secreted less EVs than the wild-type (WT). In this report, we show that the tet8 mutant was attenuated in the plant hormone jasmonate (JA) accumulation in response to mechanical wounding treatment. We also noticed that the EVs contained a high level of phospholipids phosphatidic acids (PAs) which may serve as precursors of JA biosynthesis during wound-triggered-self-healing processes. Thus, we propose an open question about a potential role of EVs or TET8 or both in damage-associated JA response.
