• A role for the adaptor proteins TRAM and TRIF in toll-like receptor 2 signaling 

      Nilsen, Nadra; Gregory I., Vladimer; Stenvik, Jørgen; Ørning, Mathias Pontus; Zeid-Kilani, Maria Vanessa; Bugge, Marit; Bergstrøm, Bjarte; Conlon, Joseph; Husebye, Harald; Amy, Hise; Fitzgerald, Katherine A.; Espevik, Terje; Lien, Egil (Journal article; Peer reviewed, 2015)
      Toll-like receptors (TLRs) are involved in sensing invading microbes by host innate immunity. TLR2 recognizes bacterial lipoproteins/lipopeptides, and lipopolysaccharide activates TLR4. TLR2 and TLR4 signal via the ...
    • Combined inhibition of complement and CD14 attenuates bacteria-induced inflammation in human whole blood more efficiently than antagonizing the toll-like receptor 4-MD2 complex 

      Gustavsen, Alice; Nymo, Stig Haugset; Landsem, Anne; Christiansen, Dorte; Ryan, Liv; Husebye, Harald; Lau, Corinna; Pischke, Søren Erik; Lambris, John D.; Espevik, Terje; Mollnes, Tom Eirik (Journal article; Peer reviewed, 2016)
      Background. Single inhibition of the Toll-like receptor 4 (TLR4)–MD2 complex failed in treatment of sepsis. CD14 is a coreceptor for several TLRs, including TLR4 and TLR2. The aim of this study was to investigate the effect ...
    • Endocytic pathways regulate Toll-like receptor 4 signaling and link innate and adaptive immunity 

      Husebye, Harald; Halaas, Øyvind; Stenmark, Harald; Tunheim, G; Sandanger, Øystein; Bogen, B; Brech, A; Latz, Eicke; Espevik, Terje (Journal article; Peer reviewed, 2006)
      Immune responses are initiated when molecules of microbial origin are sensed by the Toll‐like receptors (TLRs). We now report the identification of essential molecular components for the trafficking of the lipopolysaccharide ...
    • Mutagenesis of Uropathogenic Escherishia coli and its Effect on Macrophages 

      Chen, Carmen (Master thesis, 2021)
      Sepsis er en systemisk inflammatorisk respons ved alvorlig infeksjon som kan føre til organsvikt og død. Hvert år dør flere millioner av mennesker på grunn av sepsis, allikevel er den grunnliggende mekanismen til sepsis ...
    • Optimized differentiation of THP-1 cells into macrophages for the study of TLR4 signaling and trafficking events 

      Berg-Rolness, Håkon Schau (Master thesis, 2014)
      Toll like receptors (TLRs) are a group of membrane bound pattern recognition receptors (PRRs). TLRs are able to detect a variety of pathogen associated molecular patterns (PAMPs) and start inflammation upon recognition of ...
    • Peptide derived from SLAMF1 prevents TLR4-mediated inflammation in vitro and in vivo 

      Nilsen, Kaja Elisabeth; Zhang, Boyao; Skjesol, Astrid; Ryan, Liv; Vagle, Hilde; Bøe, Maren Helene; Orning, Pontus; Kim, Hera; Bakke, Siril Skaret; Elamurugan, Kirusika; Mestvedt, Ingvild Bergdal; Stenvik, Jørgen; Husebye, Harald; Lien, Egil; Espevik, Terje; Yurchenko, Mariya (Peer reviewed; Journal article, 2023)
      Inflammation plays a crucial role in the development and progression of many diseases, and is often caused by dysregulation of signalling from pattern recognition receptors, such as TLRs. Inhibition of key protein–protein ...
    • Regulation of Toll-like receptors signaling by vesicle transport protein ZFYVE27 

      Kompatscher, Maria (Master thesis, 2019)
      Toll like receptors (TLRs) represent members of the pattern recognition receptors and are responsible for discriminating self from non-self. In the human body, this function is executed by 11 specialized receptors present ...
    • SLAMF1 is required for TLR4-mediated TRAM-TRIF dependent signaling in human macrophages 

      Yurchenko, Mariya; Skjesol, Astrid; Ryan, Liv; Richard, Gabriel Mary; Kandasamy, Richard Kumaran; Wang, Ninghai; Terhorst, Cox; Husebye, Harald; Espevik, Terje (Journal article; Peer reviewed, 2018)
      Signaling lymphocytic activation molecule family 1 (SLAMF1) is an Ig-like receptor and a costimulatory molecule that initiates signal transduction networks in a variety of immune cells. In this study, we report that SLAMF1 ...
    • The GOLD domain-containing protein TMED7 inhibits TLR4 signalling from the endosome upon LPS stimulation 

      Doyle, SL; Husebye, Harald; Connolly, D; Espevik, Terje; O'Neill, LAJ; McGettrick, AF (Journal article; Peer reviewed, 2012)
      Toll-like receptor 4 is an innate immune receptor responsible for the recognition of the Gram-negative cell wall component lipopolysaccharide. Here we show that transmembrane emp24 domain-containing protein 7 (TMED7) ...
    • The TLR4 adaptor TRAM controls the phagocytosis of Gram-negative bacteria by interacting with the Rab11-family interacting protein 2 

      Skjesol, Astrid; Yurchenko, Mariya; Bösl, Korbinian; Gravastrand, Caroline S.; Nilsen, Kaja Elisabeth; Grøvdal, Lene Melsæther; Agliano, Federica; Patane, Francesco; Lentini, Germana; Kim, Hera; Teti, Giuseppe; Sharma, Aditya Kumar; Kandasamy, Richard Kumaran; Sporsheim, Bjørnar; Starheim, Kristian K.; Golenbock, Douglas T.; Stenmark, Harald; McCaffrey, Mary; Espevik, Terje; Husebye, Harald (Journal article; Peer reviewed, 2019)
      Phagocytosis is a complex process that eliminates microbes and is performed by specialised cells such as macrophages. Toll-like receptor 4 (TLR4) is expressed on the surface of macrophages and recognizes Gram-negative ...
