Anti-Tribbles Pseudokinase 2 (TRIB2)-Immunization Modulates Hypocretin/Orexin Neuronal Functions

Our results suggest that the general activation of the immune system modulates the functions of hypocretin neurons. The absence of a change in hypocretin cell populations suggested that factors other than anti-TRIB2 antibody play a part in the loss of hypocretin neurons in narcolepsy. The increased anti-TRIB2 antibody after the destruction of hypocretin neurons suggest that anti-TRIB2 antibody in narcolepsy patients is the consequence rather than the inciting cause of hypocretin cell destruction.
