Are Neuropeptide-Reactive T Cells behind Narcolepsy?

Abstract

Researchers have previously hypothesized autoimmune origins for narcolepsy on the basis of its strong genetic association with an MHC class II allele. In a recent issue of Nature, Latorre et al. (2018) discovered that narcolepsy patients had autoreactive T cells specific to the neuronal antigen hypocretin, providing more evidence of the potential immune origin of the disease.
