    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Fermi; Large Area Telescope; gamma-rays; dark matter; spectral lines; beam test; Physics; Fysik; Astroparticle physics; Astropartikelfysik;

    Abstract : Dark matter (DM) constitutes one of the most intriguing but so far unresolved issues in physics. In many extensions of the Standard Model of particle physics, the existence of a stable Weakly Interacting Massive Particle (WIMP) is predicted. The WIMP is an excellent DM particle candidate.

  2. 2. Early events in T cell development

    Author : Karin Leandersson; Malmö Cancerimmunologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunology; pTalpha; gammadelta T cell; alphabeta T cell; development; thymus; thymocyte; serology; transplantation; Immunologi; serologi;

    Abstract : T cells constitute a heterogenous population of lymphocytes. Their unifying property is that they express surface bound antigen-receptors, called T cell receptors (TCRs). The TCR is a heterodimer composed of either TCRalpha and beta chain proteins (alphabeta TCR) or gamma and delta chain proteins (gammadelta TCR). READ MORE

  3. 3. T lymphocytes in Wegener’s granulomatosis

    Author : Ricardo Antonio Giscombe Stephen; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Wegener s granulomatosis; T lymphocytes; TCR; T cell expansions; HLA-DRB1*0401; CTLA-4; IL-10;

    Abstract : Wegener's granulomatosis (WG) is a systemic necrotizing vasculitis that affects small and medium size blood vessels. The respiratory tract and lungs are usually compromised with necrotizing granulomatous formations. The aetiology is unknown and untreated the prognosis of generalised WG is very poor. READ MORE

  4. 4. Expansion of circulatory Vγ9Vδ2 T cells in tularemia and Pontiac fever, two intracellular bacterial diseases with widely different clinical expression

    Author : Michal Kroca; Dieter Kabelitz; Umeå universitet; []

    Abstract : Although well established that human Vγ9Vδ2 T cells may expand in circulation during intracellular bacterial infections, most underlying studies included only a few cases and only some diseases had been studied so far. In tularemia, a severe invasive disease, only one patient had been described. READ MORE

  5. 5. T Cell Ontogeny and Effector Functions in Galphai2-deficient Colitis

    Author : Malin Bjursten; Göteborgs universitet; []

    Abstract : Inflammatory bowel disease (IBD) comprising Crohn s disease and ulcerative colitis is a disease that affects millions of people worldwide, especially in northern countries such as Sweden, and is characterised by chronic uncontrolled inflammation of the intestinal mucosa. It is the general belief that multiple factors such as genetic and environmental aspects are involved in disease pathogenesis. READ MORE
