Evidence from several sources suggests that the dorsal hippocampus is critical for the formation and storage of spatial information. In the long term, such information is believed to be transferred to the neocortex for storage...
The armadillo gene—so named because its mutated form in fruit flies produces a phenotype with short spiky hairs, reminiscent of those on the armadillo—codes for a protein that is a homologue of the human β-catenin...
Atherosclerotic processes are drawing the attention of some Alzheimer's researchers who point to a number of links between atherosclerotic disease and Alzheimer's disease...
At the American Academy of Neurology meeting in Toronto, Scott Small and colleagues presented data suggesting that fMRI can distinguish early AD-related memory decline from other sources of memory
decline...
In the search for the elusive γ-secretase that
cleaves β-amyloid precursor protein (APP), much attention has been paid to the protein Notch, which is critical in developmental pathways...
Three-dimensional images of enzymes at work in cells? This is the promise of a new advance in microscopy called fluorescence lifetime imaging microscopy (FLIM)...
Fred Van Leeuwen and his colleagues reported last year (Science 9 Jan 1998;279:242-7) that some neurons in Alzheimer's patients contain mutant RNA coding for APP and ubiquitin...
β-catenin, a protein that regulates transcription, has drawn attention in Alzheimer's research because it interacts with PS1 and PS2. It was also recently found that AD patients with the PS1 mutation have markedly reduced β-catenin...
It has long been assumed that the reason Alzheimer's
patients tend to get lost is because of memory failure and confusion. But a new study appearing in tomorow’s issue of Neurology suggests that impaired processing of visual information...
Researchers in the U.K. have created conditions inside a test tube in which human prion protein can flip back and forth between normal forms and abnormal forms associated with neurodegenerative disease...
Ever since the ApoE4 allele was identified as a risk
factor in late-onset Alzheimer's, researchers have speculated that ApoE interacts with β-amyloid. Several years ago, Kelly Bales and colleagues at Lilly Research Laboratories...
The UCSD Alzheimer's Disease Cooperative Study Center is launching a $22 million study to determine whether medical intervention in individuals with mild cognitive impairment (MCI)...
In the mid-1980s, Finnish researchers reported that 68 percent of heart attack patients and 50 percent of those with coronary heart disease had antibodies to the bacterium <em>Chlamydia pneumoniae</em>, as compared to 17 percent of healthy controls...
Scientists at Sandia National Laboratories and M.I.T. have created the first computer simulation that successfully models how protein misfolding can occur...
