Abstract
Interactions with extracellular matrices (ECM) shape the signaling and functions of many types of cells and receptors, and distinct ECM coatings have been used in a wide range of substrates for drug discovery processes. Here, we investigate the influence of ECM protein coatings on the signaling of endogenous purinergic 2Y (P2Y) receptors in human embryonic kidney HEK293 cells using dynamic mass redistribution (DMR) assays enabled by label-free optical biosensor. Results showed that ECM proteins had significant impacts on the DMR characteristics, potency, and efficacy of seven P2Y agonists. This study documents the importance of surface chemistry in regulating receptor signaling.
