The fact that Pick disease is often familial, and the evidence suggesting that the epsilon 4 allele of apolipoprotein E (ApoE) is a risk factor for AD and possibly other dementias, prompted us to study ApoE isoforms in Pick disease.
These two subjects, both homozygous for the APOE-epsilon4 allele, were primarily diagnosed as having Creutzfeldt-Jakob disease and Pick's disease in the absence of significant neocortical amyloid deposition.
Human presenilin-1, but not familial Alzheimer's disease (FAD) mutants, facilitate Caenorhabditis elegans Notch signalling independently of proteolytic processing.
Huntingtin is found in areas of the brain that degenerate in this disease but is also associated with pathogenic inclusions in Alzheimer disease and Pick disease.
The decreased level of BCK in AD and PD brains might be caused by posttranscriptional events, which could affect the translation of BCK mRNA and/or lead to the inactivation and degradation of the enzyme.
Thirteen families have been described with an autosomal dominantly inherited dementia named frontotemporal dementia and parkinsonism linked to chromosome 17 (FTDP-17), historically termed Pick's disease.
In addition, the recent identification of mutations in the tau gene associated with a similar neurodegenerative condition (frontotemporal dementia and parkinsonism linked to chromosome 17) has further strengthened the argument that tau dysfunction is somehow involved in the pathogenesis of PSP.
Thirteen families have been described with an autosomal dominantly inherited dementia named frontotemporal dementia and parkinsonism linked to chromosome 17 (FTDP-17), historically termed Pick's disease.
Recently exonic and intronic mutations in the gene for microtubule-associated protein tau have been discovered in cases of familial frontotemporal dementia and parkinsonism linked to chromosome 17 (FTDP-17).
The two genes are thus positional candidates for the mutant locus underlying frontotemporal dementia and parkinsonism linked to chromosome 17 (FTDP-17), a disease for which NIK is also a good biological candidate.
Different mutations in the microtubule-associated tau protein gene have recently been identified in several families with hereditary frontotemporal dementia and Parkinsonism (FTDP-17) linked to chromosome 17q21-22.
