Illustration of the extracellular vesicles’ involvement in NAFLD development. Adipocyte-derived extracellular vesicles mediate the endocrine effects in hepatocytes, hepatic stellate cells, and macrophages (Kuffer cells) in the early phase of the NAFLD development. The disease progression becomes worse when the hepatocytes release their extracellular vesicles that promote the formation of fibrosis. The green arrow represents upregulation, and the red arrow represents downregulation.
