Lateral Hypothalamic Orexin Hypocretin Neurons is an important cell type in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
Orexin (also known as hypocretin) neurons in the lateral hypothalamus are critical for wakefulness, arousal, and energy homeostasis. These neurons are selectively lost in narcolepsy and affected in neurodegenerative diseases.
| Peptide | Precursor | Function |
|---|---|---|
| Orexin-A | Prepro-orexin | 33 amino acids, hcrt1 ligand |
| Orexin-B | Prepro-orexin | 28 amino acids, hcrtr2 ligand |
| Drug | Mechanism | Status |
|---|---|---|
| Solriamfetol | Dopamine/norepinephrine reuptake | Approved for narcolepsy |
| Pitolisant | H3 antagonist, increases histamine | Approved for narcolepsy |
The study of Lateral Hypothalamic Orexin Hypocretin Neurons has evolved significantly over the past decades. Research in this area has revealed important insights into the underlying mechanisms of neurodegeneration and continues to drive therapeutic development.
