Mitochondria-associated ER membranes in Alzheimer disease
Alzheimer disease (AD) is associated with the accumulation in the brain of extracellular neuritic plaques composed mainly of β-amyloid (Aβ) and of intracellular neurofibrillary tangles composed of hyperphosphorylated forms of the microtubule-associated protein tau. It is also associated with other features that have received less attention, including aberrant phospholipid, cholesterol, and calc...
متن کاملA mitochondrial membrane protein is required for translocation of phosphatidylserine from mitochondria-associated membranes to mitochondria.
The mechanism of import of phosphatidylserine (PtdSer) into mitochondria was investigated using a reconstituted system of isolated organelles in vitro in which PtdSer was translocated from donor membranes to mitochondria and was decarboxylated therein. Neither phosphatidylcholine nor phosphatidylethanolamine (PtdEtn) was translocated under the same conditions. Transfer of PtdSer from its site o...
متن کاملDiabetic Encephalopathy Affects Mitochondria and Axonal Transport Proteins
Introduction: Diabetic encephalopathy is described as any cognitive and memory impairments and associated with hippocampal degenerative changes, include neurodegenerative process and decreased number of living cell. Mitochondrial Diabetes (MD) appears fallowing activation of mutant mitochondrial DNA and is combination of diabetes and cognitive deficit. In this research we showed the correlation...
متن کاملα-Synuclein is localized to mitochondria-associated ER membranes.
Familial Parkinson disease is associated with mutations in α-synuclein (α-syn), a presynaptic protein that has been localized not only to the cytosol, but also to mitochondria. We report here that wild-type α-syn from cell lines, and brain tissue from humans and mice, is present not in mitochondria but rather in mitochondria-associated endoplasmic reticulum (ER) membranes (MAM), a structurally ...
متن کاملUpregulated function of mitochondria-associated ER membranes in Alzheimer disease
Alzheimer disease (AD) is associated with aberrant processing of the amyloid precursor protein (APP) by γ-secretase, via an unknown mechanism. We recently showed that presenilin-1 and -2, the catalytic components of γ-secretase, and γ-secretase activity itself, are highly enriched in a subcompartment of the endoplasmic reticulum (ER) that is physically and biochemically connected to mitochondri...
