  2. 11. Modulation of natural killer cell and T-cell functions by CD94/NKG2A receptors

    Author : Cristina Teixeira de Matos; Karolinska Institutet; Karolinska Institutet; []
    Keywords : NK cells; Dendritic cells; Inhibitory receptors; Cytokines; C1394 NKG2A; HLA-E; Inflammation; Chronic arthritis; Tumor cells.;

    Abstract : Natural Killer (NK) cells constitute a subset of lymphocytes capable of cytokine production and/or cellular cytotoxicity. Although NK cells can be activated experimentally by a multitude of agents, the in vivo mechanisms of activation and regulation are not fully elucidated. READ MORE

  4. 12. Microfluidic bases sample preparation for blood stream infections

    Author : Sahar Ardabili; Aman Russom; Mats Nilsson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; sample-preparation; microfluidics; sepsis; size-based separation; selective cell-lysis; immune-based isolation; Biotechnology; Bioteknologi;

    Abstract : Microfluidics promises to re-shape the current health-care system by transferring diagnostic tools from central laboratories to close vicinity of the patient (point-of-care). One of the most important operational steps in any diagnostic platform is sample preparation, which is the main subject in this thesis. READ MORE

  5. 13. Proteasome inhibition in the regulation of natural killer cell function and multiple myeloma cell apoptosis

    Author : Xiaoli Feng; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Multiple myeloma (MM) is a hematologic malignancy mostly occurring in the elderly and characterized by an expansion of monoclonal plasma cells in the bone marrow and increased monoclonal immunoglobulin in plasma. The outcome of this disease has been greatly improved due to introduction of new drugs. READ MORE

  6. 14. Strategies to optimize T cell-based cancer immunotherapy

    Author : Simona Vertuani; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MHC class 1; CTL; DNA vaccine; HER-2; Retinoic acid;

    Abstract : Remarkable progress has been made in the field of tumor immunology in the past decade but active immunotherapy is not yet an established treatment modality. Tumor associated antigens (TAAs) presented in the form of peptides in association with MHC class 1 can be recognized by T cells and represent major targets of immunotherapy strategies to treat cancer patients.

  7. 15. Physiology of Caldicellulosiruptor saccharolyticus: a hydrogen cell factory

    Author : Karin Willquist; Teknisk mikrobiologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; growth activation; hydrogen tolerance; hydrogen yields CO2 inhibition; physiology; enzyme kinetics; Caldicellulosiruptor saccharolyticus; biohydrogen; energy metabolism;

    Abstract : A high substrate conversion efficiency is a prerequisite for an economically feasible biohydrogen production. Caldicellulosiruptor saccharolyticus is a strictly anaerobic extreme thermophilic bacterium that is able to convert the theoretical maximum of 4 mol/mol glucose to H2. READ MORE
