Article Abstract
Medicinal plant-derived vesicle-like nanoparticles can carry chemical components and exert intercellular activity due to the encapsulation of nanostructures. American ginseng is well known as a traditional herb and is commonly used in clinical decoctions. However, the nano-characteristics and chemical composition of American-ginseng-derived vesicle-like nanoparticles (AGVNs) in decoctions are unclear. In this study, the gradient centrifugation method was used to extract and isolate AGVNs. A metabolomic method based on high-resolution mass spectrometry was established to analyze small molecules loaded in AGVNs. Zebrafish and RAW264.7 cells were employed to investigate the anti-inflammatory effects of AGVNs. The results showed that the particle size of AGVNs was generally 243.6 nm, and the zeta potential was -14.5 mV. AGVNs were found to contain 26 ginsenosides (14 protopanaxadiols, 11 protopanaxatriols, and 1 oleanolic acid). Ginsenoside Rb1 and malonyl-ginsenoside Rb1 tended to be enriched in AGVNs. Moreover, AGVNs were found to exert anti-inflammatory effects by reducing macrophage migration in zebrafish and regulating inflammatory factor (NO, TNF-α, IL-6, IL-10) secretion in RAW 264.7 cells. The characterization and analysis of AGVNs provide references and data that support the development of nanoscale anti-inflammatory substances from medicinal plants.

The fermented botanical product (FBP) is a complex, primarily plant-based fermented food that has been popular among consumers for many years. Although FBP may modulate gastrointestinal function, the responsible factors and precise mechanisms remain unclear and speculative. Extracellular vesicles (EVs) have gained widespread attention as a novel signaling system, not only in animals but also in plants and microorganisms.

Plant-derived vesicle-like nanoparticles (PDVLNs) are bioactive nanovesicles secreted by plant cells, emerging as a novel therapeutic tool for tissue repair and regeneration due to their low immunogenicity, intrinsic bioactivity, and potential as drug delivery carriers. This review examines PDVLNs' biogenesis mechanisms, isolation techniques, and compositional diversity, emphasizing their roles in promoting essential regenerative processes-cell proliferation, differentiation, migration, immune modulation, and angiogenesis. We explore their therapeutic applications across multiple tissue types, including skin, bone, neural, liver, gastrointestinal, cardiovascular, and dental tissues, using both natural and engineered PDVLNs in various disease models.

Background: Atherosclerosis, driven majorly by dyslipidemia, is a major risk factor for acute and chronic cardiovascular diseases. Hence, the development of bioactive products that can regulate lipid metabolism and prevent the onset and progression of atherosclerosis is urgently needed.
Purpose: This study aims to investigate the effect of Mori fructus-derived extracellular vesicle-like nanoparticles (MFEVLPs) on lipid abnormality and atherosclerosis progression.

Dysregulated inflammatory reactions can result in detrimental effects to the body, thereby causing various diseases. Traditional treatments relying on anti-inflammatory drugs or nanoformulations often undermine the body's physiological immune functions or potentially exhibit biotoxicity. Extracellular vesicles, which contain a diverse array of anti-inflammatory substances and possess nanomedicine transport properties, are emerging as highly promising candidates for next-generation drug delivery systems and active biological agents.
