The impairment of hypocretin neurotransmission system is considered to play a major role in the pathophysiology of narcolepsy. It has been hypothesized that autoimmune abnormalities underlie the etiology of narcolepsy, based on the tight association with HLA-DRB1*1501/ DQB1*0602. It remains unclear if autoantibodies against hypocretin receptors (hcrtrl and hcrtr2) are involved in narcolepsy.
