Aldehyde dehydrogenase (ALDH) in Alzheimer's and Parkinson's disease


Grünblatt, Edna; Riederer, Peter (2016). Aldehyde dehydrogenase (ALDH) in Alzheimer's and Parkinson's disease. Journal of Neural Transmission, 123(2):83-90.

Abstract

Evidence suggests that aldehyde dehydrogenase (ALDH; E.C. 1.2.1.3) gene, protein expression and activity are substantially decreased in the substantia nigra of patients with Parkinson's disease (PD). This holds especially true for cytosolic ALDH1A1, while mitochondrial ALDH2 is increased in the putamen of PD. Similarly, in Alzheimer's disease (AD) several studies in genetic, transcriptomic, protein and animal models suggest ALDH involvement in the neurodegeneration processes. Such data are in line with findings of increased toxic aldehydes, like for example malondialdehyde, nonenal, 3,4-dihydroxyphenylacetaldehyde and others. Genetic, transcriptomic and protein alterations may contribute to such data. Also in vitro and in vivo experimental work points to an important role of ALDH in the pathology of neurodegenerative disorders. Aims at investigating dysfunctions of aldehyde detoxification are suitable to define genetic/molecular targets for new therapeutic strategies balancing amine metabolism in devastating disorders like PD and probably also AD.
