Alzheimer’s Disease (AD) is a significant neurodegenerative condition that adversely affects memory, cognition, and motor function. It involved multiple pathologies, with amyloid beta and tau proteins playing crucial roles. Prior to observable cognitive decline, alterations in neuronal cells contribute to disease progression. Sphingomyelin, found in lipid rafts and myelin sheaths, regulates CNS cell growth, differentiation, and apoptosis. Dysregulation in sphingolipid metabolism may impact early AD stages. Ceramides, derived from sphingomyelin hydrolysis, play a role in amyloid beta-related neurodegeneration. Gangliosides, abundant in human brains, interact with cholesterol and other lipids in lipid rafts. Ongoing studies explore GM1, a type of ganglioside, and its relationship with amyloid beta aggregation, potentially influencing AD pathogenesis. Researchers can investigate lipid differences between AD and control brain samples by conducting a meta-analysis on proteomic databases, focusing on gangliosides and ceramides. Analyzing data by brain region may reveal specific dysregulated lipids and proteins in AD brains. In this book chapter, we discuss the processing of raw data sets through MS-DIAL.

摘要

Alzheimer’s Disease (AD) is a significant neurodegenerative condition that adversely affects memory, cognition, and motor function. It involved multiple pathologies, with amyloid beta and tau proteins playing crucial roles. Prior to observable cognitive decline, alterations in neuronal cells contribute to disease progression. Sphingomyelin, found in lipid rafts and myelin sheaths, regulates CNS cell growth, differentiation, and apoptosis. Dysregulation in sphingolipid metabolism may impact early AD stages. Ceramides, derived from sphingomyelin hydrolysis, play a role in amyloid beta-related neurodegeneration. Gangliosides, abundant in human brains, interact with cholesterol and other lipids in lipid rafts. Ongoing studies explore GM1, a type of ganglioside, and its relationship with amyloid beta aggregation, potentially influencing AD pathogenesis. Researchers can investigate lipid differences between AD and control brain samples by conducting a meta-analysis on proteomic databases, focusing on gangliosides and ceramides. Analyzing data by brain region may reveal specific dysregulated lipids and proteins in AD brains. In this book chapter, we discuss the processing of raw data sets through MS-DIAL.
