ABSTRACT
Extracellular vesicles (EVs) are essential components for intercellular communication, bioactive cargo trafficking, and homeostasis maintenance. The knowledge regarding the diverse functions and applications of EVs has continually expanded over the recent decade. The classification of eukaryotic EVs based on their biophysical or biochemical properties has failed to adequately capture the variety of biological effects attributed to these micro- and nano-vesicles. In this review, we specifically discuss the functional definition of EVs which possess decoying capabilities, including consequential biological interactions with toxins, pathogen- and damage- associated molecular patterns, and nutrients. We focus on the reported studies that highlight recent discoveries involving decoy EVs that intercept host immunity, further focusing on microbial pathogeneses as well as chronic illnesses. Lastly, we evaluate biomedical methodologies to suitably address research questions and uncover distinct decoying properties of these decoy EVs across various health and disease experimental settings.
