The novel target：exosoms derived from M2 macrophage.

Abstract

More and more exosome-based therapeutics are being developed with advances in nanotechnology and precision medicine. Exosome is a kind of tiny vesicles with a bilayer of phospholipids, which can transfer biological macromolecules to recipients to influence the biological process. M2 macrophages are closely related to the occurrence and development of serious diseases such as tumor. In addition to the traditional concept of macrophage functions such as opsonization, secretion of cytokines and other soluble factors, some studies have found that the exosome derived from M2 macrophages can influence the development of disease by carrying microRNA, long noncodingRNA and functional proteins to regulate target gene expression as well as related proteins synthesis recently. Here, we outlined the biogenesis of the exosome and its biological functions in disease. Then we focused on elucidating the effects of the exosome derived from M2 macrophages on several diseases and its mechanisms. Finally, we discussed the appropriateness and inappropriateness in existing potential applications based on exosomes and macrophages.
