CONCLUSIONS: These data confirm a previous report (Hollander et al., Proc Natl Acad Sci U S A 105:19480-19485, 2008) that the hypocretin receptor hcrtR1 is activated in nicotine reinforcement and in addition show that both the arcuate nucleus and lateral hypothalamus are sites at which hcrt receptor mechanisms may influence reinforcement.

Pretreatment with the hypocretin receptor 1 (Hcrtr-1) antagonist SB334867 or preprohypocretin gene deletion blocked both nicotine effects.

Neuropharmacology. 2010 Jan;58(1):185-94. Epub 2009 Jul 14.

Two receptors respond to orexin signaling, Orexin 1 Receptor (OX1R) and Orexin 2 Receptor (OX2R) with partially overlapping brain distributions.
Further, DORA attenuates the ability of nicotine to induce reinstatement of extinguished responding for a reinforcer, demonstrating selectivity of the effect to reward pathways and not to food intake.

Here we show that blockade of hypocretin transmission at hypocretin-1 (Hcrt-1; orexin-1) receptors decreases i.v. nicotine self-administration in rats and the motivation to obtain the drug.
