The Homeostatic Chemokine CCL21 Predicts Mortality and May Play a Pathogenic Role in Heart Failure
Yndestad, Arne; Finsen, Alexandra Vanessa; Ueland, Thor; Husberg, Cathrine; Dahl, Christen P.; Dickstein, Kenneth (Peer reviewed; Journal article, 2012-03-12)Background: CCL19 and CCL21, acting through CCR7, are termed homeostatic chemokines. Based on their role in concerting immunological responses and their proposed involvement in tissue remodeling, we hypothesized that these ... -
IL-18 and IL-18 binding protein are related to disease severity and parasitemia during falciparum malaria
Otterdal, Kari; Berg, Åse; Michelsen, Annika Elisabet; Yndestad, Arne; Patel, Sam; Gregersen, Ida; Halvorsen, Bente; Ueland, Thor; Langeland, Nina; Aukrust, Pål (Journal article; Peer reviewed, 2021)Background: Several inflammatory molecules participate in the immune response to malaria. Interleukin (IL)-18 is an inflammatory cytokine activated by NLRP3 inflammasomes. In clinical falciparum malaria, with and without ... -

Paradoxically, a majority of CVID patients ... -
Instability in NAD+ metabolism leads to impaired cardiac mitochondrial function and communication
Lauritzen, Knut H.; Olsen, Maria Belland; Ahmed, Mohammed Shakil; Yang, Kuan; Rinholm, Johanne Egge; Bergersen, Linda H.; Esbensen, Qin Ying; Sverkeli, Lars Jansen; Ziegler, Mathias; Attramadal, Håvard; Halvorsen, Bente; Aukrust, Pål; Yndestad, Arne (Journal article; Peer reviewed, 2021)Poly(ADP-ribose) polymerase (PARP) enzymes initiate (mt)DNA repair mechanisms and use nicotinamide adenine dinucleotide (NAD+) as energy source. Prolonged PARP activity can drain cellular NAD+ reserves, leading to de-regulation ... -
Low fibre intake is associated with gut microbiota alterations in chronic heart failure
Mayerhofer, Cristiane C.K.; Kummen, Martin; Holm, Kristian; Broch, Kaspar; Awoyemi, Ayodeji Olawale; Vestad, Beate; Larsen, Christopher Storm; Seljeflot, Ingebjørg; Ueland, Thor; Bohov, Pavol; Berge, Rolf Kristian; Svardal, Asbjørn M.; Gullestad, Lars; Yndestad, Arne; Aukrust, Pål; Hov, Johannes Espolin Roksund; Trøseid, Marius (Journal article; Peer reviewed, 2020)Aims Recent reports have suggested that patients with heart failure (HF) have an altered gut microbiota composition; however, associations with diet remain largely uninvestigated. We aimed to explore differences in the ... -
NLRP3 inflammasome deficiency attenuates metabolic disturbances involving alterations in the gut microbial profile in mice exposed to high fat diet
Sokolova, Marina; Yang, Kuan; Hansen, Simen Hyll; Louwe, Mieke C.; Kummen, Martin; Hov, Johannes Espolin Roksund; Sjaastad, Ivar; Berge, Rolf Kristian; Halvorsen, Bente; Aukrust, Pål; Yndestad, Arne; Ranheim, Trine (Journal article; Peer reviewed, 2020)Obesity-related diseases (e.g. type 2 diabetes mellitus and cardiovascular disorders) represent an increasing health problem worldwide. NLRP3 inflammasome activation may underlie obesity-induced inflammation and insulin ... -

The NLRP3 inflammasome is an innate immune sensor that can be ... -
OXR1A, a Coactivator of PRMT5 Regulating Histone Arginine Methylation

We find that male mice with brain-specific isoform A knockout (Oxr1A−/−) develop fatty liver. RNA sequencing of male Oxr1A−/− liver indicates ... -
Plasma levels of interleukin 27 in falciparum malaria is increased independently of co-infection with HIV: potential immune-regulatory role during malaria
