• 21-Hydroxylase-Specific CD8+ T Cells in Autoimmune Addison’s Disease Are Restricted by HLA-A2 and HLA-C7 Molecules 

      Hellesen, Alexander; Aslaksen, Sigrid; Breivik, Lars Ertesvåg; Røyrvik, Ellen Christine; Bruserud, Øyvind; Edvardsen, Kine Susann Waade; Brokstad, Karl Albert; Wolff, Anette Susanne Bøe; Husebye, Eystein Sverre; Bratland, Eirik (Journal article; Peer reviewed, 2021)
      Objectives: CD8+ T cells targeting 21-hydroxylase (21OH) are presumed to play a central role in the destruction of adrenocortical cells in autoimmune Addison’s disease (AAD). Earlier reports have suggested two immunodominant ...
    • Avoiding organelle mutational meltdown across eukaryotes with or without a germline bottleneck 

      Edwards, David; Røyrvik, Ellen Christine; Chustecki, Joanne; Giannakis, Konstantinos; Glastad, Robert Clay; Radzvilavicius, Arunas; Johnston, Iain (Journal article; Peer reviewed, 2021)
      Mitochondrial DNA (mtDNA) and plastid DNA (ptDNA) encode vital bioenergetic apparatus, and mutations in these organelle DNA (oDNA) molecules can be devastating. In the germline of several animals, a genetic “bottleneck” ...
    • Data-Driven Inference Reveals Distinct and Conserved Dynamic Pathways of Tool Use Emergence across Animal Taxa 

      Johnston, Iain George; Røyrvik, Ellen Christine (Journal article; Peer reviewed, 2020)
      Tool use is a striking aspect of animal behavior, but it is hard to infer how the capacity for different types of tool use emerged across animal taxa. Here we address this question with HyperTraPS, a statistical approach ...
    • GWAS for autoimmune Addison's disease identifies multiple risk loci and highlights AIRE in disease susceptibility 

      Eriksson, Daniel; Røyrvik, Ellen Christine; Aranda-Guillen, Maribel; Berger, Amund Holte; Landegren, Nils; Artaza, Haydee; Hallgren, Åsa; Grytaas, Marianne; Strøm, Sara; Bratland, Eirik; Botusan, Ileana; Oftedal, Bergithe Eikeland; Breivik, Lars Ertesvåg; Vaudel, Marc; Helgeland, Øyvind; Falorni, Alberto; Jørgensen, Anders Palmstrøm; Hulting, Anna-Lena; Svartberg, Johan; Ekwall, Olov; Fougner, Kristian J; Wahlberg, Jeanette; Nedrebø, Bjørn Gunnar; Dahlqvist, Per; Study group, Norwegian Addison Registry; Study Group, Swedish Addison Registry; Knappskog, Per Morten; Wolff, Anette Susanne Bøe; Bensing, Sophie; Johansson, Stefan; Kämpe, Olof; Husebye, Eystein Sverre (Journal article; Peer reviewed, 2021)
      Autoimmune Addison’s disease (AAD) is characterized by the autoimmune destruction of the adrenal cortex. Low prevalence and complex inheritance have long hindered successful genetic studies. We here report the first ...
    • MtDNA sequence features associated with 'selfish genomes' predict tissue-specific segregation and reversion 

      Røyrvik, Ellen Christine; Johnston, Iain (Journal article; Peer reviewed, 2020)
      Mitochondrial DNA (mtDNA) encodes cellular machinery vital for cell and organism survival. Mutations, genetic manipulation, and gene therapies may produce cells where different types of mtDNA coexist in admixed populations. ...
    • Primary ovarian insufficiency in women with Addison's disease 

      Vogt, Elinor Margrethe Chelsom; Breivik, Lars Ertesvåg; Røyrvik, Ellen Christine; Grytaas, Marianne; Husebye, Eystein Sverre; Øksnes, Marianne (Journal article; Peer reviewed, 2021)
      Context Primary ovarian insufficiency (POI) is defined by menopause before 40 years of age. POI prevalence is higher among women with autoimmune Addison’s disease (AAD) than in the general population, but their clinical ...
