Amyloid Precursor Protein and Amyloid b Peptide in Human Platelets
The main component of Alzheimer’s disease (AD) senile plaques is amyloid-b peptide (Ab), a proteolytic fragment of the amyloid precursor protein (APP). Platelets contain both APP and Ab and may contribute to the perivascular amyloid deposition seen in AD. However, no data are available concerning the biochemical mechanism(s) involved in their formation and release by these cells. We found that ...
متن کاملProtein misfolding, functional amyloid, and human disease.
Peptides or proteins convert under some conditions from their soluble forms into highly ordered fibrillar aggregates. Such transitions can give rise to pathological conditions ranging from neurodegenerative disorders to systemic amyloidoses. In this review, we identify the diseases known to be associated with formation of fibrillar aggregates and the specific peptides and proteins involved in e...
متن کاملMouse amyloid protein AA: Homology with nonimmunoglobulin protein of human and monkey amyloid substance.
The major protein extracted from anyloid deposits induced in mice by injection of either Candida albicans cells or sodium caseinate was found to have chromatographic and electrophoretic properties and an amino-acid compostiion characteristic of the AA class of amyloid proteins. The homology of the mouse protein with protein AA from man and monkey was established by determination of the sequence...
متن کاملHeterogeneity of human serum amyloid A protein
Serum amyloid A (SAA), a chemically polymorphic protein, is the most sensitive marker protein of the acute phase and the precursor of reactive amyloidosis, which is characterized by deposits of amyloid A protein (AA). We investigated the variability of the SAA gene family in one individual by sequencing 11 SAA-specific clones from an acute-phase-liver cDNA library. At least five different SAA v...
متن کاملInter-individual variability contrasts with regional homogeneity in the human brain DNA methylome
The possibility that alterations in DNA methylation are mechanistic drivers of development, aging and susceptibility to disease is widely acknowledged, but evidence remains patchy or inconclusive. Of particular interest in this regard is the brain, where it has been reported that DNA methylation impacts on neuronal activity, learning and memory, drug addiction and neurodegeneration. Until recen...
