CHAPEL HILL, NC – In the continuing effort to improve upon opioid pain relievers, American and Chinese scientists used cryoEM technology to solve the detailed structures of the entire family of opioid receptors bound to their naturally occurring peptides. Subsequent structure-guided biochemical studies were then performed to better understand the mechanisms of peptide-receptor selectivity and signaling drugs.
This work, published in Cell, provides a comprehensive structural framework that should help drug developers rationally design safer drugs to relieve severe pain. Read more
