Abstract

Previous studies have shown that NAD(P)+ transhydrogenase (NNT) is relevant to maintenance of mitochondrial redox balance in mouse brain, especially under physiologically challenging conditions, such as after treatment with a high-fat diet. In this sense, this project aims at study the role of NNT activity in the development of age-related changes in the central nervous system using a mouse model. Changes in mitochondrial bioenergetics, oxidative damage and morphological changes related to aging in the brain of mice with and without functional NNT will be characterized. Besides, changes in neurotransmission and putative behavioral phenotypes in mice devoid of functional NNT will be evaluated. Methodological approaches will include behavioral assays, assessment of the bioenergetic and redox balance in isolated mitochondria, assessment of oxidative damage markers, immunoenzymatic assays and immunohistochemical and immunofluorescence analyzes in brain.
