Programmable Modulation for Extracellular Vesicles
Abstract Every living cell releases extracellular vesicles (EVs) that are critical for cellular signaling and a wide range of biological functions. The potential diagnostic and therapeutic applications of EVs are well recognized, and rapidly expanding. While a complete understanding of the molecular mechanisms underpinning EVs release remains elusive, here we demonstrate a novel method for programmable control of the release of EVs and their cargo using external electric fields. As a proof of principle, we use cultured rat astrocytes to demonstrate how the frequency of external electrical stimulation selectively modulates EV release, their surface proteins, and microRNA profiles. This method could broadly impact biological science and medical applications. First, it raises an interesting question of how endogenous electrical activity could modulate EV production. Second, it provides a novel mechanism for tuning therapeutic electrical stimulation that may be useful for treating brain disorders. Third, it provides a new way to generate EVs carrying desired cargos by tuning electrical stimulation parameters. Unlike chemical methods for creating EVs, electrical stimulation is a clean physical method with adjustable parameters including stimulation frequency, field strength and waveform morphology..
