[New Insights into Diagnosis and Pathogenesis of Amyloidosis by Mass Spectrometric Analysis].

Amyloidosis is one of the most well-known protein-misfolding diseases caused by the deposition of insolu- ble amyloid fibrils in extracellular spaces. At least 31 amyloid fibril proteins have been identified. To elu- cidate the pathogenesis and diagnose the type of amyloidosis, mass spectrometric techniques, including liquid chromatography/tandem mass spectrometry and matrix-assisted laser desorption/ionization time of flight mass spectrometry, have been widely used for the analysis of biological samples, such as serum, urine, and tissues. We review new insights into the diagnosis and pathogenesis of amyloidosis using several mass spectrometric methods. [Review].
