  2. 1. The quality control of MHC class I antigen presentation

    Author : Kajsa M Paulsson; Antigen presentation; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; chaperone; assembly; COPI; antigenic peptide; TAP; MHC; tapasin; Immunology; serology; transplantation; Immunologi; serologi;

    Abstract : Major histocompatibility complex (MHC) class I molecules present antigenic peptides to CD8+ T cells. The peptides are generated by proteasomes in the cytosol, then translocated across the membrane of the endoplasmic reticulum (ER) by the transporter associated with antigen processing (TAP).

  4. 2. Streptococcal M protein and human C4BP

    Author : Jenny J Persson; Avdelningen för medicinsk mikrobiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Infektioner; Infections; Medicin människa och djur ; Medicine human and vertebrates ; human C4BP; M protein; antigenic variation; sequence variability; Streptococcus pyogenes; innate immunity;

    Abstract : Antigenic variation of surface proteins allows microorganisms to evade the immune system of the infected host. This phenomenon represents an apparent paradox, because the variable protein must retain an important function, while its antigenic properties vary extensively. READ MORE

  5. 3. Studies on streptococcal M proteins. Interactions with IgA and human complement regulators

    Author : Eskil Johnsson; Institutionen för laboratoriemedicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microbiology; antigenic variation; factor H; C4b-binding protein; Fc-receptor; IgA; Streptococcus pyogenes; M protein; mykologi; virologi; bakteriologi; Mikrobiologi; virology; mycology; bacteriology;

    Abstract : The human pathogenic bacterium Streptococcus pyogenes (group A Streptococcus) expresses several different virulence factors. Of these, the M protein is regarded as one of the most important, because it confers resistance to phagocytosis, allowing the bacterium to multiply in blood. READ MORE

  6. 4. Glycoprotein G of Herpes simplex virus type 2. Antigenicity and genetic variability

    Author : Jan-Åke Liljeqvist; Göteborgs universitet; []
    Keywords : Herpes simplex virus type 2; glycoprotein G; antigenic regions; sequence variability;

    Abstract : Herpes simplex virus type 2 (HSV-2) causes genital lesions, meningitis and occasionally, severe neonatal infections. Globally HSV-2 infection is one of the most common sexually transmitted diseases. READ MORE

  7. 5. Antigenic variation and virulence in Plasmodium falciparum malaria : studies on the surface protein PfEMP1

    Author : Karin Blomqvist; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Approximately 40% of the world’s population is at risk of contracting malaria, a disease caused by the intracellular protozoan Plasmodium. The species Plasmodium falciparum is responsible for the majority of severe morbidity and mortality. READ MORE
