Publication Brief Description
The nociceptin/orphanin FQ (N/OFQ) opioid peptide and its receptor (NOPR) are critical regulators of motivation, stress, feeding, and sleep, and growing evidence identifies the NOP receptor as a promising target for the treatment of addiction, insomnia, and depression. However, studying the dynamics of the N/OFQ-NOPR peptide system has been challenging due to limitations in existing detection methods.
The research groups led by Michael R. Bruchas and Tommaso Patriarchi developed NOPLight by engineering a human NOPR-based fluorescent sensor with high ligand selectivity, subsecond activation kinetics, and minimal interference with cellular signaling. NOPLight was validated in HEK293T cells, neurons, brain slices, and freely moving mice, demonstrating its ability to detect both exogenous NOPR agonists and endogenous N/OFQ release during behaviors like reward-seeking, aversion, and feeding. This sensor provides a powerful tool for investigating neuropeptide signaling and its role in neural circuits and behavior.
