Insulin and Insulin-Sensitizing Drugs in Neurodegeneration: Mitochondria as The...
Cardoso, Susana; Santos, Renato; Correia, Sonia; Carvalho, Cristina; Zhu, Xiongwei; Lee, Hyoung-Gon; Casadesu, Gemma; Smith, Mark A.; Perry, GeorgeInsulin, besides its glucose lowering effects, is involved in the modulation of lifespan, aging and memory and learning processes. As the population ages, neurodegenerative disorders become epidemic and a connection between insulin signaling dysregulation, cognitive decline and dementia has been established. Mitochondria are intracellular organelles that despite playing a critical role in cellular metabolism ar...
Tau phosphorylation in Alzheimer's disease: pathogen or protector?
Lee, Hyoung-gon; Perry, George; Moreira, Paula I.; Garrett, Matthew R.; Liu, Quan; Zhu, Xiongwei; Takeda, Atsushi; Nunomura, Akihiko; Smith, Mark A.During the past decade, hypotheses concerning the pathogenesis of most neurodegenerative diseases have been dominated by the notion that the aggregation of specific proteins and subsequent formation of cytoplasmic and extracellular lesions represent a harbinger of neuronal dysfunction and death. As such, in Alzheimer's disease, phosphorylated tau protein, the major component of neurofibrillary tangles, is consi...
Redox metals and oxidative abnormalities in human prion diseases
Petersen, Robert; Siedlak, Sandra; Lee, Hyoung-Gon; Kim, Yong-Sun; Nunomura, Akihiko; Tagliavini, Fabrizio; Ghetti, Bernardino; Cras, PatrickPrion diseases are characterized by the accumulation of diffuse and aggregated plaques of protease-resistant prion protein (PrP) in the brains of affected individuals and animals. Whereas prion diseases in animals appear to be almost exclusively transmitted by infection, human prion diseases most often occur sporadically and, to a lesser extent, by inheritance or infection. In the sporadic cases (sporadic Creut...
