Abstract: There is an urgent need to search for biomarkers that are indicative of neurodegenerative diseases, as the clinical diagnosis of
which remains unsatisfactory. Mass spectrometry (MS) has been playing an important role in studying peptide and protein identities, structures,
modifications and interactions that collectively drive their biological functions. MS-based proteomics technology is thus well suited for the
biomarker discovery. This article reviews the overall strategies and workflows employed for biomarker discovery and recent applications of
MS-based proteomics in neurodegenerative diseases. Special emphasis is placed on the studies of protein post-translational modification
pattern changes and differential peptidomics under these pathological conditions.(IJCEP806008 ).
Key Words: Biomarker, neurodegenerative diseases, proteomics, peptidomics, post-translational modifications, mass spectrometry
