The effects of an irreversible long term opioid antagonism on circadian rhythms in body temperature (Tb), locomotor activity (Act) and feeding under normal conditions and following lipopolysaccharide administration (LPS; 2.5 mg/kg) have been investigated in unrestrained mice housed at their

Opioids activate the descending antinociceptive pathway from the ventrolateral periaqueductal gray (vlPAG) by both pre- and postsynaptic inhibition of tonically active GABAergic neurons (i.e., disinhibition). Previous research has shown that short-term desensitization of postsynaptic μ-opioid receptors (MOPrs) in the vlPAG

The profiles of action of beta-funaltrexamine (beta-FNA) and beta-chlornaltrexamine (beta-CNA) have been assessed in the mouse vas deferens preparation. beta-FNA, but not beta-CNA, demonstrated a reversible agonist action that appeared to be mediated via kappa-receptor interaction. beta-CNA produced an irreversible

Previously, we showed that kappa-selective ligands inhibit adenylyl cyclase in guinea pig cerebellar membranes. The present studies explore the relationship between kappa 1 binding sites (as determined with [3H]U-69,593 binding) and kappa 1-inhibition of adenylyl cyclase (using U-50,488H) in guinea

Buprenorphine is a weak partial agonist at mu-opioid receptors that is used for treatment of pain and addiction. Intracellular and whole-cell recordings were made from locus ceruleus neurons in rat brain slices to characterize the actions of buprenorphine. Acute application
