Alpha-synuclein inclusions in Alzheimer and Lewy body diseases.
Alpha-synuclein has assumed particular neuropathological interest in the light both of its identification as a non-beta-amyloid plaque constituent in Alzheimer disease (AD), and the recent association between dominant inheritance of Parkinson disease (PD) and 2 missense mutations at positions 30 and 53 of the synuclein protein. We report a systematic study of alpha-synuclein, tau, and ubiquitin...
متن کاملExogenous alpha-synuclein fibrils seed the formation of Lewy body-like intracellular inclusions in cultured cells.
Cytoplasmic inclusions containing alpha-synuclein (alpha-Syn) fibrils, referred to as Lewy bodies (LBs), are the signature neuropathological hallmarks of Parkinson's disease (PD). Although alpha-Syn fibrils can be generated from recombinant alpha-Syn protein in vitro, the production of fibrillar alpha-Syn inclusions similar to authentic LBs in cultured cells has not been achieved. We show here ...
متن کاملp62/SQSTM1-Dependent Autophagy of Lewy Body-Like α-Synuclein Inclusions
α-Synuclein is the main component of Lewy bodies, the intraneuronal inclusion bodies characteristic of Parkinson's disease. Although α-synuclein accumulation is caused by inhibition of proteasome and autophagy-lysosome, the degradation of α-synuclein inclusions is still unknown. Formation of Lewy body-like inclusions can be replicated in cultured cells by introducing α-synuclein fibrils generat...
متن کاملalpha-Synuclein in filamentous inclusions of Lewy bodies from Parkinson's disease and dementia with lewy bodies.
Lewy bodies and Lewy neurites are the defining neuropathological characteristics of Parkinson's disease and dementia with Lewy bodies. They are made of abnormal filamentous assemblies of unknown composition. We show here that Lewy bodies and Lewy neurites from Parkinson's disease and dementia with Lewy bodies are stained strongly by antibodies directed against amino-terminal and carboxyl-termin...
متن کاملSelective degeneration fo Purkinje cells with Lewy body-like inclusions in aged NFHLACZ transgenic mice.
Transgenic (NFHLacZ) mice expressing a fusion protein composed of a truncated high-molecular-weight mouse neurofilament (NF) protein (NFH) fused to beta-galactosidase (LacZ) develop inclusions in neurons throughout the CNS. These inclusions persist from birth to advanced age and contain massive filamentous aggregates including all three endogenous NF proteins and the NFHLacZ fusion protein. Fur...
