nervous system
• basal firing rates are selectively increased in locus coeruleus (LC) neurons but not in medial habenula (MHb) neurons
• firing of MHb neurons is significantly reduced by DAMGO (a synthetic enkephalin-mimetic peptide) at a low concentration (0.3 um), which has no significant effect in wild-type MHb neurons
• MHb neurons show a significantly greater net inhibition of neuronal firing by DAMGO both at a low (0.3 um) and high (1 uM) concentration
• following washout of DAMGO (1 uM), recovery kinetics of MHb neurons is significantly slower than that in wild-type MHb neurons, indicating greater susceptibility to opioid inhibition
• firing of LC neurons is significantly reduced by morphine at 0.1 um, which has no significant effect in wild-type LC neurons

behavior/neurological
N
• at ~4 months of age, mice exhibit normal baseline learning, nociception, locomotor activity, habituation to an unfamiliar environment and motor coordination relative to wild-type controls
• mice exhibit significantly reduced withdrawal signs (diarrhea, jumps, dog shakes, paw tremor, back walking, tremor and ptosis) and weight loss due to naloxone-precipitated somatic withdrawal after chronic morphine exposure
• in a conditioned place preference paradigm, mice exhibit augmented responses to the rewarding effects of morphine, in agreement with increased opioid sensitivity of MHb neurons
• mice exhibit enhanced morphine-induced analgesia in thermal (hot plate and tail immersion) and mechanical (Von Frey) pain paradigms, as shown by increases in both maximal response and effect duration across multiple morphine doses
• administration of JNJ-63533054 (a GPR139 agonist) fails to diminish morphine-induced (10mg/kg) analgesia in a dose-dependent manner in the thermal and mechanical pain paradigms, unlike in wild-type control mice

growth/size/body
N
• at ~4 months of age, mice exhibit normal health, body weight and body composition relative to wild-type controls
