High impact information on Hcrtr2

  • Moreover, orexin-A, which exerts its effects through orexin receptor type 1 and orexin receptor type 2 with similar potency, resulted in a significant increase in wakefulness duration by 17.1% (n = 6, P < 0.05), 184.0% (n = 6, P < 0.01) and 228.6% (n = 6, P < 0.01) at doses of 0.1, 1 and 10 nmol, respectively [2].
  • The effects of third ventricle intracerebroventricular (ICV) infusion of the novel orexin receptor type 2 selective agonist, [Ala11]orexin-B, on the sleep-wake cycle were investigated [2].
  • The subsets of infiltrating mononuclear cells were investigated using MoAbs against rat CD4+ T cell (W3/25), CD8+ T cell (CX8), B cell (OX33) and macrophage (OX42) [3].
