Orexin B also known as hypocretin 2 is a neuropeptide with a molecular mass of about 2 kDa. It is one of the two types of orexins the other being orexin A. Orexin B is produced in the lateral hypothalamus and is found mainly in the brain. The neuropeptide binds to the orexin receptor type 2 (HCRTR2) to initiate its actions. The lateral hypothalamus synthesizes orexin B and then it is distributed broadly across neurological circuits. Orexin B plays an important role in regulating wakefulness and food intake by interacting with its receptor.
Biological function summary
Orexin B influences wakefulness energy metabolism and appetite regulation. It does not function alone but as part of the broader orexin neuropeptide system which includes orexin A and their respective receptors forming a regulatory network. The actions of orexin B impact the arousal system effectively enhancing alertness when appropriately activated. The neuropeptide's modulation of the sleep-wake cycle and feeding behaviors indicates its relevance in maintaining critical homeostatic circuits within the central nervous system.
Pathways
Orexin B is significantly involved in the sleep-wake cycle and feeding regulatory pathways. Within these pathways orexin B interacts closely with neurotransmitters and receptors like norepinephrine and the HCRTR2 receptor. This interaction supports its role in maintaining wakefulness and energy balance. During activation orexin B influences the locus coeruleus an important site of noradrenergic neuron activity linking it to broader neurophysiological processes critical to arousal and stress response mechanisms.
Disruptions in orexin B activity lead to conditions such as narcolepsy and obesity. Narcolepsy a sleep disorder characterized by debilitating daytime drowsiness connects to changes in orexin signaling particularly those affecting orexin receptors and their interaction with orexin A. Orexin B's relation to obesity stems from its influence on food intake and energy balance bridging metabolic disorders and neuropathological conditions. Research into these connections emphasizes the therapeutic potential of targeting this neuropeptide system to manage sleep disorders and metabolic diseases.
