The effect of Helicobacter pylori-derived extracellular vesicles on glucose metabolism and induction of insulin resistance in HepG2 cells

Extracellular vesicles in Helicobacter pylori-mediated diseases: mechanisms and therapeutic potential

Extracellular vesicles (EVs) are relevant elements for cell-to-cell communication and are considered crucial in host-pathogen interactions by transferring molecules between the pathogen and the host during infections. These structures participate in various physiological and pathological processes and are considered promising candidates as disease markers, therapeutic reagents, and drug carriers. Both H. pylori and the host epithelial cells infected by H. pylori secrete EVs, which contribute to inflammation and the development of disease phenotypes. However, many aspects of the cellular and molecular biology of EV functions remain incompletely understood due to methodological challenges in studying these small structures. This review also highlights the roles of EVs derived from H. pylori-infected cells in the pathogenesis of gastric and extragastric diseases. Understanding the specific functions of these EVs during H. pylori infections, whether are advantageous to the host or the pathogen, may help the development new therapeutic approaches to prevent disease.
