Searching for reliable premortem protein biomarkers for prion diseases: progress and challenges to date.
Prion diseases are a unique family of fatal neurodegenerative diseases caused by abnormal folding of normal cellular prion proteins in the brain. Due to the high risk of prion disease transmission and the lack of effective treatment to cure or delay the disease progression, prion diseases pose a serious threat to public health. To control and prevent prion diseases, an early diagnosis is urgently needed. Proteomic analysis has emerged as a powerful technology to decipher biological and pathophysiological processes and identify protein biomarkers indicative of disease. In this article, the authors review the use of the latest proteomic technologies for the identification of promising prion disease biomarkers, the challenges that exist in biomarker development pipelines and the new directions for utilizing proteomics for future biomarker discovery in the context of prion disease diagnostics.
