Increased plasma level of tumor necrosis factor α in patients with narcolepsy in Taiwan.

Highlights: [•] Narcolepsy patients have higher plasma level of tumor necrosis factor α (TNF α) than control subjects. [•] Our data indicate that elevated TNF α is involved in the pathophysiology of narcolepsy. [•] However, three promoter single nucleotide polymorphisms of TNF-α gene are not associated with narcolepsy. [ABSTRACT FROM AUTHOR]
