Methylglyoxal Alzheimer

Methylglyoxal, a reactive intermediate of cellular metabolism, is the most potent precursor of AGEs and is strictly correlated with an increase of oxidative stress in Alzheimer's disease One of the most effective detoxification systems for methylglyoxal and glyoxal is the glutathione-dependent glyoxalase system, consisting of glyoxalase I and glyoxalase II. In this study, we have determined the methylglyoxal and glyoxal levels in the cerebrospinal fluid of AD patients compared to healthy controls

Portofrei bestellen oder in der Filiale abholen Alzheimer's disease (AD) is a neurodegenerative disorder characterized by the deposition of extracellular amyloid-beta peptide (A╬▓) and intracellular neurofibrillar tangles, associated with loss of neurons in the brain and consequent learning and memory deficits. A╬▓ is the major component of the senile plaques and is believed to play a central role in the development and progress of AD. Advanced glycation end products (AGEs) play a major role in age-related diseases like Alzheimer's disease. 1,2-dicarbonyl compounds, such as glyoxal (GO) and methylglyoxal (MGO), are involved in the formation of these AGEs. Thus, it was hypothesised that the progression of Alzheimer's disease can be slowed down by lowering the concentration of 1,2-dicarbonyl compounds, which will consequently. Advanced glycation end products (AGEs) are found in various intraneuronal protein deposits such as neurofibrillary tangles in Alzheimer's disease and Lewy bodies in Parkinson's disease. Among the many reactive carbonyl compounds and AGE precursors, methylglyoxal is most likely to contribute to intracellular AGE formation, since it is extremely reactive and constantly produced by degradation of.
