Dynamics of immune effector mechanisms during infection with Mycobacterium aviumin C57BL/6 mice
Haug, Markus; Awuh, Jane Atesoh; Steigedal, Magnus; Kojen, June Frengen; Marstad, Anne; Nordrum, Ivar Skjåk; Halaas, Øyvind; Flo, Trude Helen (Journal article; Peer reviewed, 2013)Opportunistic infections with non-tuberculous mycobacteria such as Mycobacterium avium are receiving renewed attention because of increased incidence and difficulties in treatment. As for other mycobacterial infections, a ... -
Human Toll-like Receptor 8 (TLR8) Is an Important Sensor of Pyogenic Bacteria, and Is Attenuated by Cell Surface TLR Signaling
Moen, Siv Helen; Ehrnström, Birgitta; Kojen, June Frengen; Yurchenko, Mariya; Beckwith, Kai Sandvold; Afset, Jan Egil; Damås, Jan Kristian; Zhenyi, Hu; Hang, Yin; Espevik, Terje; Stenvik, Jørgen (Journal article; Peer reviewed, 2019)TLR8 is an endosomal sensor of RNA degradation products in human phagocytes, and is involved in the recognition of viral and bacterial pathogens. We previously showed that in human primary monocytes and monocyte derived ... -
TIRAP/Mal Positively Regulates TLR8‐Mediated Signaling via IRF5 in Human Cells
Nilsen, Kaja Elisabeth; Skjesol, Astrid; Kojen, June Frengen; Espevik, Terje; Stenvik, Jørgen; Yurchenko, Mariya (Peer reviewed; Journal article, 2022)Toll-like receptor 8 (TLR8) recognizes single-stranded RNA of viral and bacterial origin as well as mediates the secretion of pro-inflammatory cytokines and type I interferons by human monocytes and macrophages. TLR8, as ... -
TLR8 and complement C5 induce cytokine release and thrombin activation in human whole blood challenged with Gram-positive bacteria
Ehrnstrøm, Birgitta; Kojen, June Frengen; Giambelluca, Miriam; Ryan, Liv; Moen, Siv Helen; Hu, Zhenyi; Yin, Hang; Mollnes, Tom Eirik; Damås, Jan Kristian; Espevik, Terje; Stenvik, Jørgen (Journal article; Peer reviewed, 2020)We recently showed that TLR8 is critical for the detection of Gram‐positive bacteria by human monocytes. Here, we hypothesized that TLR8 and complement together regulate antibacterial responses in human blood. Anticoagulated ... -
TLR8 senses Staphylococcus aureus RNA in human primary monocytes and macrophages and induces IFN-β production via a TAK1-IKKβ-IRF5 signaling pathway
Bergstrøm, Bjarte; Aune, Marie Hjelmseth; Awuh, Jane Atesoh; Kojen, June Frengen; Blix, Kjetil Jordahl; Ryan, Liv; Flo, Trude Helen; Mollnes, Tom Eirik; Espevik, Terje; Stenvik, Jørgen (Journal article, 2015)
