Orexin-1 receptor signaling increases motivation for cocaine-associated cues.
The orexin/hypocretin system is involved in multiple cocaine addiction processes that involve drug-associated environmental cues, including cue-induced reinstatement of extinguished cocaine seeking and expression of conditioned place preference. However, the orexin system does not play a role in several behaviors that are less cue-dependent, such as cocaine-primed reinstatement of extinguished ...
متن کاملOrexin/hypocretin signaling at the orexin 1 receptor regulates cue-elicited cocaine-seeking.
The orexin/hypocretin system has recently been implicated in reward-processing and addiction. We examined the involvement of the orexin system in cue-induced reinstatement of extinguished cocaine-seeking by administering the orexin 1 receptor antagonist SB-334867 (SB) or the orexin 2 receptor antagonist 4-pyridylmethyl (S)-tert-leucyl 6,7-dimethoxy-1,2,3,4-tetrahydroisoquinoline (4PT) prior to ...
متن کاملDynein Light Chain Tctex-Type 1 Modulates Orexin Signaling through Its Interaction with Orexin 1 Receptor
Orexins (OX-A, OX-B) are neuropeptides involved in the regulation of the sleep-wake cycle, feeding and reward, via activation of orexin receptors 1 and 2 (OX1R, OX2R). The loss of orexin peptides or functional OX2R has been shown to cause the sleep disorder, narcolepsy. Since the regulation of orexin receptors remains largely undefined, we searched for novel protein partners of the intracellula...
متن کاملShort Title Histamin-1 Receptor in Orexin Signaling
Aim: The effect of orexin on wakefulness has been shown to be largely mediated by activation of histaminergic neurons via orexin receptor-2 (OX2R). Consistently, OX2R mRNA is abundantly expressed in histaminergic neurons in the tuberomammillary nucleus (TMN). However, orexin receptors in the other regions of the brain might also play important roles in maintenance of wakefulness. To dissect the...
متن کاملOrexin A/hypocretin-1 selectively promotes motivation for positive reinforcers.
Orexin A/hypocretin-1 (oxA/hcrt-1) is known to be a modulator of dopamine-dependent neuronal activity and behaviors. However, the role of this system in driving motivated behaviors remains poorly understood. Here, we show that orexin/hypocretin receptor-1 (ox/hcrt-1R) signaling is important for motivation for highly salient, positive reinforcement. Blockade of ox/hcrt-1R selectively reduced wor...
