Small extracellular vesicles mediated signaling and pain
Abstract Chronic pain is the most prevalent, disabling, and expensive public health condition in the United States. The goal of this project is to elucidate how to harness body’s own analgesic mechanisms to provide pain relief. We propose to investigate 30-150 nm small extracellular vesicles (sEVs) that transport mRNAs, miRNAs, proteins, and lipid mediators to recipient cells via circulation. Uptake of sEVs induce gene expression changes in recipient cells and thus, sEVs play an important role in intercellular communication. We observed that sEVs from RAW 264.7 macrophage cells show therapeutic and prophylactic efficacy in a complete Freud adjuvant (CFA) mouse model of inflammatory pain.…
