Proteomic profiling of the hypothalamus in two mouse models of narcolepsy.

Narcolepsy is a disabling neurological disorder of sleepiness linked to the loss of neurons producing orexin neuropeptides in the hypothalamus. Two well-characterized phenotypic mouse models of narcolepsy, loss-of-function (orexin-knockout), and progressive loss of orexin (orexin/ataxin-3) exist. The open question is whether the proteomics signatures of the hypothalamus would be different between the two models.
