Research on Alzheimer's disease in Japan: a personal view on history and present status
Abstract
Research on Alzheimer's disease (AD) in Japan is briefly reviewed based mainly on our work. Paired helical filaments (PHF) have been extensively investigated for their components and phosphorylation. Their analysis has no yet provided important insights into the mechanism of neuronal death in AD brain. In beta-amyloidogenesis, the carboxyl extent of amyloid beta-protein (Abeta) is now highlighted. Abeta42, not Abeta40, is the initially deposited species. Future investigations should elucidate why Abeta42 is deposited in the brain parenchyma and how the Abeta deposition leads to PHF formation.

Alzheimer's Disease: APP
Amyloid precursor protein (APP) proteolysis is critical for the development of Alzheimer's disease, a neurodegenerative disease associated with accumulation of amyloid plaques in the brain. Here is the latest research on APP and Alzheimer's disease.
Alzheimer's Disease: Amyloid Beta
Alzheimer's disease is a neurodegenerative disease associated with the accumulation of amyloid plaques in the brain; these plaques are comprised of amyloid beta deposits. Here is the latest research in this field.
