Precedent for the role of influenza exposure initiating neurological disorder, potentially via molecular mimicry, exists for Guillain-Barre syndrome (205) and narcolepsy, in which hypocretin-producing neurons could be an autoimmune target due to molecular mimicry between H1N1 virus-derived antigen and a neuronal autoantigen in HLA-DQB1*06:02 positive patients (206, 207); see (208) for an example model of narcolepsy. The gene discussed is HLA-DQB1; the disease is narcolepsy.
