Abstract excerpt
BACKGROUND: A recent genetic study in mice and humans revealed the modulatory effect of MC1R (melanocortin-1 receptor) gene variants on kappa-opioid receptor mediated analgesia. It is unclear whether this gene affects basal pain sensitivity or the efficacy of analgesics acting at the more clinically relevant mu-opioid receptor. OBJECTIVE: To characterise sensitivity to pain and mu-opioid analgesia in mice and...
