Ganglioside profiling by ion mobility and mass spectrometry imaging identifies distinct biomolecular isomers in Niemann-Pick Disease
Gangliosides are glycosphingolipids implicated in the neurodegenerative pathology of Niemann-Pick disease type C2 (NPC2 disease), where accumulation of GM2 and GM3 is a hallmark of disrupted lipid trafficking and disease progression. Some gangliosides are structural isomers with identical molecular composition and mass, making them difficult to distinguish by mass spectrometry imaging (MSI) alone…
