The most popular current hypothesis is that Alzheimer's disease (AD) is caused by aggregates of the amyloid peptide (Abeta), which is generated by cleavage of the Abeta protein precursor (APP) by beta-secretase (BACE-1) followed by gamma-secretase. BACE-1 cleavage is limiting for the production of Abeta, making it a particularly good drug target for the(More)
Alzheimer's disease (AD) and Parkinson's disease (PD) share several pathological mechanisms. The parallels between amyloid beta (Abeta) in AD and alpha-synuclein in PD have been discussed in several reports. However, studies of the last few years show that Abeta also shares several important characteristics with neuromelanin (NM), whose role in PD is(More)
Amyloid-beta (Abeta) accumulates in several types of retinal degeneration and in Alzheimer's disease (AD), but its source has been unclear. We detected the neuronal 695 amino acid form of amyloid-beta protein precursor (AbetaPP) in the normal retina and AbetaPP751 in the retinal pigment epithelium (RPE) and anterior eye tissues. Similar to the brain, alpha-(More)
Alzheimer's disease (AD) is a complex neurodegenerative disorder with a progressive mental deterioration manifested by memory loss. No definite etiology has been established for AD to date. Amyloid beta (Abeta) protein plays a central role in the pathology of AD through multiple pathways like oxidative stress, apoptosis etc. Recently, our laboratory first(More)
