    • Elevated Plasma Levels of P‐Selectin Glycoprotein Ligand‐1 Positive Microvesicles in Patients with Unprovoked Venous Thromboembolism 

      Jamaly, Simin; Basavaraj, Manjunath Goolyam; Starikova, Irina; Olsen, Randi; Brækkan, Sigrid K.; Hansen, John-Bjarne (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-05-31)
      Background<br> Microvesicles (MVs) express antigens from their parental cells and have a highly procoagulant surface. Animal studies suggest that P‐Selectin Glycoprotein Ligand‐1 positive (PSGL‐1+) MVs play a role in the pathogenesis of venous thromboembolism (VTE).<p> Objective<br> The aim of this study was to determine plasma levels, the cellular origin and the morphological characteristics ...

    • Impact of preanalytical conditions on plasma concentration and size distribution of extracellular vesicles using Nanoparticle Tracking Analysis 

      Jamaly, Simin; Ramberg, Cathrine; Olsen, Randi; Latysheva, Nadezhda; Webster, Paul; Sovershaev, Timofey; Brækkan, Sigrid Kufaas; Hansen, John-Bjarne (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-11-21)
      Optimal pre-analytical handling is essential for valid measurements of plasma concentration and size distribution of extracellular vesicles (EVs). We investigated the impact of plasma preparation, various anticoagulants (Citrate, EDTA, CTAD, Heparin), and fasting status on concentration and size distribution of EVs measured by Nanoparticle Tracking Analysis (NTA). Blood was drawn from 10 healthy ...

    • Interplay of immune and kidney resident cells in the formation of tertiary lymphoid structures in lupus nephritis 

      Jamaly, Simin; Rakaee, Mehrdad; Abdi, Reza; tsokos, George; Fenton, Kristin Andreassen (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-10-27)
      Kidney involvement confers significant morbidity and mortality in patients with systemic lupus erythematosus (SLE). The pathogenesis of lupus nephritis (LN) involves diverse mechanisms instigated by elements of the autoimmune response which alter the biology of kidney resident cells. Processes in the glomeruli and in the interstitium may proceed independently albeit crosstalk between the two is ...

    • A modified clot-based assay to measure negatively charged procoagulant phospholipids 

      Ramberg, Cathrine; Jamaly, Simin; Latysheva, Nadezhda; Wilsgård, line; Sovershaev, Timofey; Snir, Omri; Hansen, Jesper (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-04-29)
      Growing evidence supports a role for extracellular vesicles (EVs) in haemostasis and thrombosis due to exposure of negatively charged procoagulant phospholipids (PPL). Current commercial PPL-dependent clotting assays use chemically phospholipid depleted plasma to measure PPL activity. The purpose of our study was to modify the PPL assay by substituting the chemically phospholipid depleted plasma ...

    • Prognostic Value of Macrophage Phenotypes in Resectable Non–Small Cell Lung Cancer Assessed by Multiplex Immunohistochemistry 

      Rakaee, Mehrdad; Busund, Lill-Tove; Jamaly, Simin; Paulsen, Erna-Elise; Richardsen, Elin; Andersen, Sigve; Al-Saad, Samer; Bremnes, Roy M.; Dønnem, Tom; Kilvær, Thomas Karsten (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-02-10)
      Macrophages are important inflammatory cells that regulate innate and adaptive immunity in cancer. Tumor-associated macrophages (TAMs) are thought to differentiate into two main phenotypes: proinflammatory M1 and protumorigenic M2. Currently, the prognostic impact of TAMs and their M1 and M2 phenotypes is unclear in non–small cell cancer (NSCLC). The present study was set up to evaluate an approach ...

    • Role of Extracellular Vesicles in the Pathogenesis of Venous Thromboembolism 

      Jamaly, Simin (Doctoral thesis; Doktorgradsavhandling, 2018-06-13)
      Venous thromboembolism (VTE) is a common disease with an incidence of 1–2 per 1000 individuals. VTE is a collective term for deep vein thrombosis and pulmonary embolism. Extracellular vesicles (EVs) are lipid-membrane-bound spherical vesicles that bud off from the cells upon activation and apoptosis. Their size varies between 30 nm and 1 μm. Recent advances in experimental and observational studies ...
