  1. 6. Cellular Immune Responses to Cytomegalovirus

    Författare :Anna Karin Lidehäll; Olle Korsgren; Thomas Tötterman; Ineke ten Berge; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cytomegalovirus; cellular immunology; infection; immune responses; congenital infection; CD4 T cells; CD8 T cells; immunosuppressed; Clinical immunology; Klinisk immunologi;

    Sammanfattning : Cytomegalovirus (CMV) is a widespread infection affecting 50-90% of the human population. A typical silent primary infection is followed by life-long persistence in the host under control by virus-specific CD8 (“killer”) and CD4 (“helper”) T cells. LÄS MER

  3. 7. Cytomegalovirus Infection in Immunocompetent and Renal Transplant Patients : Clinical Aspects and T-cell Specific Immunity

    Författare :Fredrik Sund; Britt-Marie Eriksson; Olle Korsgren; Halvor Rollag; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cytomegalovirus; renal transplantation; cellular immunity; valacyclovir; mismatched; prophylaxis; tetramer; CD4 T cells; CD8 T cells; Infectious diseases; Infektionssjukdomar;

    Sammanfattning : Cytomegalovirus (CMV) is a β-herpesvirus that, after primary infection, establishes a life-long persistence in the human host. Up to 90% of humans are infected with CMV, that is kept under control by CMV-specific CD8+ and CD4+ T cells. In patients with an impaired cellular immunity, however, CMV infections can be life-threatening. LÄS MER

  4. 8. CD8alpha/alpha+ T-cells and immune memory

    Författare :Isabelle Magalhaes; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : A better understanding of T-cell memory formation is crucial for rationale vaccine design and the identification of correlates of immune protection. The CD8αα homodimer expressed on CD8+ T-cells is not anymore considered to represent a TCR co-receptor, it may rather represent a mechanism to modulate T-cell avidity and identify a subset of memory T-cells.

  5. 9. Innate and adaptive immunity in genital HSV-2 infection: Implications for vaccine development

    Författare :Ali M Harandi; Göteborgs universitet; []
    Nyckelord :genital herpes infection; natural antibody; CD4 T cells; CD8 T cells; IFN-g; IL-12; IL-18; CC chemokines; dendritic cells.;

    Sammanfattning : Herpes simplex virus type 2 (HSV-2) is a sexually transmitted pathogen that infects the genital tract mucosa and is the most common case of genital ulcers in humans. Despite numerous studies, little is known about the mechanisms involved in immune protection and no anti-herpes vaccine has been developed to date. LÄS MER

  7. 10. The leukocyte complexity and mutational landscape of periampullary adenocarcinoma. Morphology matters

    Författare :Sebastian Lundgren; Tumörmikromiljö; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; periampullary adenocarcinoma; pancreatic cancer; immune microenviroment; prognosis; macrophages; natural killer cells; natural killer T cells; T cells; B cells;

    Sammanfattning : Background: Periampullary adenocarcinomas are a heterogenous group of tumours with poor prognosis that hasnot improved considerably the last decades. Tumour morphology, i.e. intestinal type (I-type) or pancreatobiliarytype (PB-type), has been demonstrated to be a more relevant prognostic factor than anatomical origin. LÄS MER
