Abstract
Exosomes are intrinsic membrane-based vesicles that play a key role in both normal and pathological processes. Since their discovery, exosomes have been investigated as viable drug delivery systems and clinical indicators because of their magnitude and effectiveness in delivering biological components to targeted cells. Exosome characteristics are biocompatible, prefer tumor recruitment, have tunable targeting efficiency, and are stable, making them outstanding and eye-catching medication delivery systems for cancer and other disorders. There is great interest in using cell-released tiny vesicles that activate the immune system in the age of the fast development of cancer immunotherapy. Exosomes, which are cell-derived nanovesicles, have a lot of potential for application in cancer immunotherapy due to their immunogenicity and molecular transfer function. More significantly, exosomes can transfer their cargo to specified cells and so affect the phenotypic and immune-regulation capabilities of those cells. In this article, we summarize exosomes' biogenesis, isolation techniques, drug delivery, applications, and recent clinical updates. The use of exosomes as drug-delivery systems for small compounds, macromolecules, and nucleotides has recently advanced. We have tried to give holistic and exhaustive pieces of information showcasing current progress and clinical updates of exosomes.
