A candidate gene for the chromosome 1 Alzheimer's disease (AD) locus was identified (STM2). The predicted amino acid sequence for STM2 is homologous to that of the recently cloned chromosome 14 AD gene (S182). A point mutation in STM2, resulting in the substitution of an isoleucine for an asparagine (N141l), was identified in affected people from Volga(More)
The cortical deposition of Abeta is an event that occurs in Alzheimer's disease, Down's syndrome, head injury, and normal aging. Previously, in appraising the effects of different neurochemical factors that impact upon the solubility of Abeta, we observed that Zn2+ was the predominant bioessential metal to induce the aggregation of soluble Abeta at pH 7.4(More)
Wilson disease (WD) is an autosomal recessive disorder characterized by the toxic accumulation of copper in a number of organs, particularly the liver and brain. As shown in the accompanying paper, linkage disequilibrium & haplotype analysis confirmed the disease locus to a single marker interval at 13q14.3. Here we describe a partial cDNA clone (pWD) which(More)
Familial Alzheimer's disease (FAD) is a genetically heterogeneous disorder that includes a rare early–onset form linked to mutations in the amyloid b protein precursor (APP) gene. Clues to the function of APP derive from the recent finding that it is a member of a highly conserved protein family that includes the mammalian amyloid recursor–like protein(More)
Familial Alzheimer's disease (FAD) is a genetically heterogeneous disorder that includes a rare early-onset form linked to mutations in the amyloid b protein precursor (APP) gene. Clues to the function of APP derive from the recent finding that it is a member of a highly conserved protein family that includes the mammalian amyloid precursor-like protein(More)
ADAM10, a member of a disintegrin and metalloprotease family, is an alpha-secretase capable of anti-amyloidogenic proteolysis of the amyloid precursor protein. Here, we present evidence for genetic association of ADAM10 with Alzheimer's disease (AD) as well as two rare potentially disease-associated non-synonymous mutations, Q170H and R181G, in the ADAM10(More)
AIM Although advances in the treatment of schizophrenia have been made, little is known about the process of recovery from first episode of schizophrenia (FES). To date, the study of recovery in the field of mental health has focused on long-term mental illness. This qualitative study addresses ways in which individuals with FES describe their process of(More)
The epsilon 4 allele of apolipoprotein E (APOE) has been found to be a risk factor for late-onset Alzheimer's disease (AD). While the pathogenic mechanism of APOE in AD is not yet clear, APOE isoforms appear to differentially influence the aggregation of A beta, the principal component of Alzheimer-associated beta-amyloid deposits. To date, no data are(More)
The generation of Aβ, the main component of senile plaques in Alzheimer's disease (AD), is precluded by α-secretase cleavage within the Aβ domain of the amyloid precursor protein (APP). We identified two rare mutations (Q170H and R181G) in the prodomain of the metalloprotease, ADAM10, that cosegregate with late-onset AD (LOAD). Here, we addressed the(More)
Familial Alzheimer's disease mutations in the presenilin 1 gene (PSEN1) have been previously shown to potentiate caspase activation and apoptosis in transfected cells and transgenic mice. However, the mechanism underlying this effect is not known. We set out to determine whether cellular sensitivity to caspase activation could be affected by modulating(More)
