What is Orexin B?
Endogenous orexin-family peptide that supports wakefulness and arousal, with strong activity at OX2R. It is used in sleep-circuit and narcolepsy research.
Key Benefits & Mechanisms
wake maintenance
sleep architecture research
orexin receptor pharmacology
Research Summary
Orexin B complements orexin A in stabilizing arousal states and is important for understanding hypersomnia and narcolepsy biology. Most use is experimental in receptor and circuit studies.
