Abstract

Protein signalling between tissues, or tissue cross-talk is becoming recognised as a fundamental biological process that is incompletely understood. Shotgun proteomic analyses of tissues and plasma to explore this concept are regularly challenged by high dynamic range of protein abundance, which limits the identification of lower abundance proteins. In this viewpoint article, we highlight how a focus on proteins contained within extracellular vesicles (EVs) not only partially addresses this issue, it can reveal a underappreciated complexity of the circulating proteome in various physiological and pathological contexts. Furthermore, we highlight how quantitative proteomics can inform EV mediated cross talk and stress the importance of high coverage, sensitive proteomic analyses of EVs to identify both the optimal methods to isolate EV subtypes of interest and proteins that characterise them.
