Elevated CD3+ and CD8+ tumor-infiltrating immune cells correlate with prolonged survival in glioblastoma patients despite integrated immunosuppressive mechanisms in the tumor microenvironment and at the systemic level
(Peer reviewed; Journal article, 2013-11-15)We characterized GBM patients' tumor and systemic immune contexture with aim to reveal themechanisms of immunological escape, their impact on patient outcome, and identify targets for immunotherapy. Increased CD3+ T-cell ... -
Natural killer cells in intracranial neoplasms: presence and therapeutic efficacy against brain tumours
(Peer reviewed; Journal article, 2014-01)Natural killer (NK) cells are lymphocytes that play an important role in anti-tumour immunity. Their potential against brain cancer has been demonstrated in vitro and in vivo, both as a direct anti-tumour agent and in ... -
Immunological mechanisms of tumour progression. The rationale for natural killer cell based immunotherapy for glioblastoma
(Doctoral thesis, 2013-10-04)Glioblastoma (GBM) is the most frequent and malignant brain tumour, where the patients’ median survival after diagnosis is only 14.6 months. Therefore, concerted research is required to develop novel treatments that will ... -
CellSegm - a MATLAB toolbox for high-throughput 3D cell segmentation
(Peer reviewed; Journal article, 2013-08-09)The application of fluorescence microscopy in cell biology often generates a huge amount of imaging data. Automated whole cell segmentation of such data enables the detection and analysis of individual cells, where a manual ... -
Correlations between measures of executive attention and cortical thickness of left posterior middle frontal gyrus - a dichotic listening study
(Peer reviewed; Journal article, 2009-10-01)Background: The frontal lobe has been associated to a wide range of cognitive control functions and is also vulnerable to degeneration in old age. A recent study by Thomsen and colleagues showed a difference between a young ... -
Evaluating Extracellular Matrix influence on adherent cell signaling by Cold Trypsin Phosphorylation-specific Flow Cytometry
(Peer reviewed; Journal article, 2013-08-19)Background: Tissue microenvironments comprise different extracellular matrix (ECM) proteins that regulate cellular responsiveness to growth factors. In vitro culture of adherent cells on ECM-coated substrata is commonly ... -
Interstitial fluid: the overlooked component of the tumor microenvironment?
(Peer reviewed; Journal article, 2010-07-23)Background: The interstitium, situated between the blood and lymph vessels and the cells, consists of a solid or matrix phase and a fluid phase, together constituting the tissue microenvironment. Here we focus on the ... -
Regulation and function of tumor suppressor p53 isoforms beta and gamma in Acute Myeloid Leukemia
(Master thesis, 2013-06-01)Research has proposed that the C-terminal truncated p53 isoforms beta and gamma enhance chemosensitivity in p53(null) cancer cell lines. Their high expression in acute myeloid leukemia (AML) patients correlates positively ... -
Activated NK cells are potent effectors against glioblastoma cells due to activating KIR2DS2 and KIR2DS4 - HLA ligand interactions - In vitro study
(Master thesis, 2013-06-03)Background: Glioblastoma (GBM) is the most malignant brain tumor, where patients' median survival is only 14,6 months after diagnosis, thus novel, effective adjuvant therapies are required. Natural Killer (NK) cells are ... -
Hyperbaric oxygen therapy and cancer—a review
(Peer reviewed; Journal article, 2012-10-02)Hypoxia is a critical hallmark of solid tumors and involves enhanced cell survival, angiogenesis, glycolytic metabolism, and metastasis. Hyperbaric oxygen (HBO) treatment has for centuries been used to improve or cure ... -
Evaluation of Prebiotic and Probiotic Effects on the Intestinal Gut Microbiota and Histology of Atlantic salmon (Salmo salar L.)
(Peer reviewed; Journal article, 2011)In the present study the impact on gut microbiology and indigenous gut histology of Atlantic salmon (Salmo salar L.) was investigated following feeding of a control and a prebiotic (EWOS prebiosal®) diet and ex vivo exposure ... -
Histological and bacteriological changes in intestine of beluga (Huso huso) following ex vivo exposure to bacterial strains
(Peer reviewed; Journal article, 2011-04-04)In the present study the intestinal sac method (ex vivo) was used to evaluate the interactions between lactic acid bacteria and staphylococci in the gastrointestinal (GI) tract of beluga (Huso huso). The distal intestine ... -
The Peripheral Binding of 14-3-3γ to Membranes Involves Isoform-Specific Histidine Residues
(Peer reviewed; Journal article, 2012-11-26)Mammalian 14-3-3 protein scaffolds include seven conserved isoforms that bind numerous phosphorylated protein partners and regulate many cellular processes. Some 14-3-3-isoforms, notably γ, have elevated affinity for ... -
Phenylalanine Hydroxylase from Legionella pneumophila Is a Thermostable Enzyme with a Major Functional Role in Pyomelanin Synthesis
(Peer reviewed; Journal article, 2012-09-26)Background: Legionella pneumophila is a pathogenic bacterium that can cause Legionnaires’ disease and other non-pneumonic infections in humans. This bacterium produces a pyomelanin pigment, a potential virulence factor ... -
Developing Neurons Form Transient Nanotubes Facilitating Electrical Coupling and Calcium Signaling with Distant Astrocytes
(Peer reviewed; Journal article, 2012-10-11)Despite the well-documented cooperation between neurons and astrocytes little is known as to how these interactions are initiated. We show here by differential interference contrast microscopy that immature hippocampal ... -
