In the last decades, extracellular vesicles have emerged as important elements in cell-cell communication and as key players in disease pathogenesis via transmission of their cargo between different cells. Various works have described different subpopulations of these membrane structures, based on their cell of origin, biogenesis, size, biophysical properties and cargo. In addition to their pathophysiological role in the development and progression of different diseases including infectious diseases, neurodegenerative disorders and cancer, extracellular vesicles are now recognized for their potential as novel therapeutic targets and intelligent drug delivery system. Here, we have reviewed the most recent data on different subtypes of extracellular vesicles, focusing on microvesicles and exosomes and their subpopulations, their involvement in immune-mediated pathogenesis of various infectious diseases and their role as potential therapeutic targets.
Keywords: Exosomes; extracellular vesicles; immune-mediated pathogenesis; immunopathology; infectious diseases; microparticles; microvesicles.
