Defective mitochondrial DNA homeostasis in the substantia nigra in Parkinson disease
Dölle, Christian; Flønes, Irene Hana; Sanchez Nido, Gonzalo; Miletic, Hrvoje; Osuagwu, Nelson; Kristoffersen, Stine; Lilleng, Peer Kåre; Larsen, Jan Petter; Tysnes, Ole-Bjørn; Haugarvoll, Kristoffer; Bindoff, Laurence; Tzoulis, Charalampos (Peer reviewed; Journal article, 2016-11-22)Increased somatic mitochondrial DNA (mtDNA) mutagenesis causes premature aging in mice, and mtDNA damage accumulates in the human brain with aging and neurodegenerative disorders such as Parkinson disease (PD). Here, we ... -
Early Forms of α-Synuclein Pathology Are Associated with Neuronal Complex I Deficiency in the Substantia Nigra of Individuals with Parkinson’s Disease
Flønes, Irene Hana; Nyland, Harald Inge; Sandnes, Dagny Ann; Alves, Guido Werner; Tysnes, Ole-Bjørn; Tzoulis, Charalampos (Journal article; Peer reviewed, 2022)Idiopathic Parkinson’s disease (iPD) is characterized by degeneration of the dopaminergic substantia nigra pars compacta (SNc), typically in the presence of Lewy pathology (LP) and mitochondrial respiratory complex I (CI) ... -
Mitochondrial respiratory chain deficiency correlates with the severity of neuropathology in sporadic Creutzfeldt-Jakob disease
Flønes, Irene Hana; Ricken, Gerda; Klotz, Sigrid; Lang, Alexandra; Ströbel, Thomas; Dölle, Christian; Kovacs, Gabor G.; Tzoulis, Charalampos (Journal article; Peer reviewed, 2020)Mitochondrial dysfunction has been implicated in multiple neurodegenerative diseases but remains largely unexplored in Creutzfeldt-Jakob disease. Here, we characterize the mitochondrial respiratory chain at the individual ... -
Mitochondrial respiratory chain dysfunction—A hallmark pathology of idiopathic Parkinson’s disease?
Flønes, Irene Hana; Tzoulis, Charalampos (Journal article; Peer reviewed, 2022)Parkinson’s disease (PD) is the most common age-dependent neurodegenerative synucleinopathy. Loss of dopaminergic neurons of the substantia nigra pars compacta, together with region- and cell-specific aggregations of ...
