Phosphotungstic acid (PTA)-precipitated brain homogenates from FTLD-synuclein, dementia with Lewy bodies (DLB) and G51D SNCA synucleinopathy cases were used to seed aggregation in α-syn140*A53T-YFP HEK293T cells. The structure of α-synuclein filaments from an FTLD-synuclein case was determined by cryo-EM. RESULTS: We identified 283 cases of MSA. Four cases had a clinical diagnosis of CBS, one of which met pathological criteria for FTLD-synuclein. Genetic studies in this case were negative for SNCA ...RESULTS: We identified 283 cases of MSA. Four cases had a clinical diagnosis of CBS, one of which met pathological criteria for FTLD-synuclein. Genetic studies in this case were negative for SNCA variants, and PTA-precipitated brain homogenates seeded abundant cytoplasmic α-synuclein inclusions that were morphologically indistinguishable from those of typical MSA but distinct from those of G51D SNCA and DLB. MSA Type II α-synuclein filaments were identified by cryo-EM. CONCLUSIONS: FTD/CBS is rarely associated with MSA pathology. The cell seeding characteristics and cryo-EM findings support the classification of FTLD-synuclein as a subtype of MSA, differentiating ...CONCLUSIONS: FTD/CBS is rarely associated with MSA pathology. The cell seeding characteristics and cryo-EM findings support the classification of FTLD-synuclein as a subtype of MSA, differentiating it from genetic synucleinopathies, such as those with SNCA variants G51D and A53E, which have neuropathological features overlapping with MSA and Lewy body diseases. These cases expand the clinicopathological spectrum of MSA and FTLD and have implications for our understanding of selective neuronal vulnerability in MSA and the interpretation of α-synuclein biomarker studies. | |||||||||
