This study shows that increasing μ-opioid receptor density promotes trafficking via GRK2/3 and β-arrestin interactions, while class B GPCRs block trafficking by sequestering β-arrestin.

This study investigates how membrane permeability affects the potency of fentanyl and isotonitazene, finding that fentanyl's extreme potency may be due to its ability to accumulate in membranes and repartition to bind receptors.

The paper investigates whether CCR8 is a high-affinity receptor for CCL18 and finds that CCR8 does not respond to CCL18 in multiple assays.

The paper investigates the role of GRK subfamilies in phosphorylation of the MOR C-tail and their impact on β-arrestin2 recruitment, showing GRK2/3 and GRK5/6 have distinct contributions.

This study evaluates the in vitro functional profiles of fentanyl and nitazene analogs at the μ-opioid receptor, finding that high intrinsic efficacy in Gi signaling correlates with increased risk of intoxication, regardless of signaling bias.

This study shows that anxiety increases pain in an osteoarthritis model and reduces opioid effectiveness by altering endogenous opioid function.
