ADA2 is a lysosomal deoxyadenosine deaminase acting on DNA involved in regulating TLR9-mediated immune sensing of DNA
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-10-22)Although adenosine deaminase 2 (ADA2) is considered an extracellular ADA, evidence questions the physiological relevance of this activity. Our study reveals that ADA2 localizes within the lysosomes, where it is targeted through modifications of its glycan structures. We show that ADA2 interacts with DNA molecules, altering their sequences by converting deoxyadenosine (dA) to deoxyinosine (dI). We ... -
The Sámi Pathfinders: Addressing the Knowledge Gap in Norwegian Mainstream Education
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-07-02)For at least two decades, lack of knowledge about the Sámi in Norway has been recognised as a reason for the perpetuation of stereotypes and discriminatory acts and hate speech towards them. Education about the Sámi, their lifeways, culture and rights is posited as a means of closing this gap, with the intention of influencing the majority Norwegian society’s attitudes towards the Sámi. The ... -
