CONFERENCE COVERAGE 1998-07-18 Conference Coverage Soto (Abstract 295) presented data documenting the ability of their 11 and 5 amino-acid inhibitors to inhibit initial Aβ peptide aggregation and its ability to dissociate already formed Aβ fibrils in vitro. In addition to the assays me
CONFERENCE COVERAGE 1998-07-18 Conference Coverage Bruce Yankner took time out from his talk on Down's syndrome (Abstract 7) to discuss his recent injection studies in young versus aged rhesus monkeys, published in the July issue of Nature Medicine. His key findings were that inje
RESEARCH NEWS 1998-05-20 Research News The brains of Alzheimer's disease victims are peppered with neuritic plaques-microscopic, spherical structures containing, among other things, deposits of β amyloid peptide, dead and dying neurons and evidence of inflammation. The infla
RESEARCH NEWS 1998-05-18 Research News Synucleins are small cytoplasmic proteins that are found in synaptic terminals. They are present in senile plaques and Lewy bodies (features of Alzheimer's disease and familial Parkinson's disease). Synucleins also bind amyloid pep
RESEARCH NEWS 1998-05-01 Research News (From Nature Biotechnology press release.) Each cell in our bodies contains 46 chromosomes. But one day far in the future, doctors may give us an extra miniature chromosome containing therapeutic genes to treat disease. Researchers are curre
RESEARCH NEWS 1998-04-09 Research News Breeding “knockout” mice is a prized tool for evaluating the function of genes, but it is a ponderous and costly tool, consuming many months and thousands of dollars to create each new knockout strain. But that could soon change. In today’s
RESEARCH NEWS 1998-04-09 Research News A gene on the long arm of chromosome 6 has been linked to an inherited form of Parkinson’s disease, called autosomal recessive juvenile parkinsonism (AR-JP). The research team of Nobuyoshi Shimizu and colleagues at Keio University School of
RESEARCH NEWS 1998-01-22 Research News Researchers trying to study the role of presenilin-1 (PS1) in Alzheimer's pathogenesis have been stymied by the fact that presenilin knockout mice die before birth. Bart De Strooper from the Flemish Institute of Biotechnology in Belgium
RESEARCH NEWS 1998-01-01 Research News Two recent papers describe the processes involved in the final stages of apoptotic cell death. During apoptosis, enzymes known as caspases break down cellular proteins, causing severe morphological changes and cell shrinkage. In the final st
RESEARCH NEWS 1997-12-18 Research News A pathologic form of prion protein is believed to cause scrapie, bovine spongiform encephalopathy and Creutzfeldt-Jakob disease. The normal function of prion protein is yet unknown, but a recent study by Hans Kretzschmar of the University of
RESEARCH NEWS 1997-12-18 Research News Why is the adult mammalian central nervous system unable to regenerate damaged axons? Scarring of glial tissue may be a factor, according to Jerry Silver and his colleagues at Case Western Reserve University School of Medicine. The researche
RESEARCH NEWS 1997-12-18 Research News An innovative microscope has been developed which provides scientists with a new window through which to explore the dynamics of molecular order and disorder in living cells and other quasi-liquid systems. Originally conceived by famed cell
RESEARCH NEWS 1997-11-24 Research News Researchers at California-based Affymetrix have analyzed the activity of every gene in the yeast genome in a single experiment using a new "DNA chip." This remarkable technological feat hints of a future, following completion of th
RESEARCH NEWS 1997-10-16 Research News Scientists working in Oxford University and Duke University Medical Center this week reported the discovery of two new genetic risk factors for late-onset Alzheimer’s disease. Nearly 90 percent of all Alzheimer's cases are late-onset, a
