    • Kidney tertiary lymphoid structures in Lupus Nephritis develop into large interconnected networks and resemble lymph nodes in gene signature 

      Dorraji, Seyed Esmaeil; Kanapathippillai, Premasany; Hovd, Aud-Malin Karlsson; Stenersrød, Mikael Ryan; Horvei, Kjersti Daae; Ursvik, anita; Figenschau, Stine; Thiyagarajan, Dhivya Borra; Fenton, Christopher Graham; Pedersen, Hege Lynum; Fenton, Kristin Andreassen (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-08-16)
      Immune aggregates organized as tertiary lymphoid structures (TLS) are observed within the kidneys of patients with systemic lupus erythematosus and lupus nephritis (LN). Renal TLS was characterized in lupus-prone New Zealand black × New Zealand white F1 mice analyzing cell composition and vessel formation. RNA sequencing was performed on transcriptomes isolated from lymph nodes, macrodissected TLS ...

    • LMW Heparin Prevents Increased Kidney Expression of Proinflammatory Mediators in (NZBxNZW)F1 Mice 

      Hedberg, Annica; Kanapathippillai, Premasany; Rekvig, Ole Petter; Fenton, Kristin Andreassen (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      We have previously demonstrated that continuous infusion of low molecular weight (LMW) heparin delays autoantibody production and development of lupus nephritis in (NZBxNZW)F1 (B/W) mice. In this study we investigated the effect of LMW heparin on renal cytokine and chemokine expression and on nucleosome-mediated activation of nucleosome-specific splenocytes. Total mRNA extracted from kidneys of ...

    • Mesenchymal stem cells and T cells in the formation of Tertiary Lymphoid Structures in Lupus Nephritis 

      Dorraji, Seyed Esmaeil; Hovd, Aud-Malin Karlsson; Kanapathippillai, Premasany; Bakland, Gunnstein; Eilertsen, Gro Østli; Figenschau, Stine; Fenton, Kristin Andreassen (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-05-18)
      Tertiary lymphoid structures (TLS) develop in the kidneys of lupus-prone mice and systemic lupus erythematosus (SLE) patients with lupus nephritis (LN). Here we investigated the presence of mesenchymal stem cells (MSCs) in the development of TLS in murine LN, as well as the role of human MSCs as lymphoid tissue organizer (LTo) cells on the activation of CD4+ T cells from three groups of donors ...

    • Positron emission tomography and single photon emission computed tomography imaging of tertiary lymphoid structures during the development of lupus nephritis 

      Dorraji, Seyed Esmaeil; Oteiza, Ana; Kuttner, Samuel; Martin, Armas Maria Montserrat; Kanapathippillai, Premasany; Garbarino, Sara; Kalda, Gustav; Scussolini, Mara; Piana, Michele; Fenton, Kristin Andreassen (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-08-03)
      Lymphoid neogenesis occurs in tissues targeted by chronic inflammatory processes, such as infection and autoimmunity. In systemic lupus erythematosus (SLE), such structures develop within the kidneys of lupus-prone mice ((NZBXNZW)F1) and are observed in kidney biopsies taken from SLE patients with lupus nephritis (LN). The purpose of this prospective longitudinal animal study was to detect early ...

    • Stromal impact on tumor growth and lymphangiogenesis in human carcinoma xenografts 

      Rikardsen, Oddveig G; Hadler-Olsen, Elin Synnøve; Steigen, sonja eriksson; Ljones, Hilde; Grenman, Reidar; Kanapathippillai, Premasany; Winberg, Jan-Olof; Svineng, Gunbjørg; Uhlin-Hansen, Lars (Journal article; Tidsskriftartikkel; Peer reviewed, 2010)
