Prion disease and endoplasmic reticulum stress pathway correlations and treatment pursuits
Abstract Background: Transmissible spongiform encephalopathies are a collection of rare neurodegenerative disorders characterized by loss of neuronal cells, astrocytosis, and plaque formation. The causative agent of these diseases is thought to be abnormally folded prions and is characterized by a conformational change from normal, cellular prion protein (PrPc) to the abnormal form (PrPTSE). Although, there is evidence that normal prion protein can contribute to these disorders. The unfolded protein response, a conserved series of pathways involved in resolving stress associated with unfolded protein accumulation in the Endoplasmic Reticulum (ER), has been shown to play a role in regulating the development of prion diseases. Methods: This review chose papers based on their relevance to current studies involved in prion protein synthesis and transformation, identifies various links between prion diseases and ER stress, and reports on current and potential treatments as they relate to ER stress and prion diseases. Conclusion: For the advancement of prion disease treatment, it is important to understand the mechanisms involved in prion formation, and ER stress is implicated in prion disease progression. Therefore, targeting the ER or pathways involved in response to stress in the ER may help us treat prion diseases.
