  1. 1. Antigenic variation in relapsing fever Borrelia

    University dissertation from Umeå : Umeå universitet

    Author : Nils Burman; Umeå universitet.; [1994]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Borrelia; Relapsing fever; Antigenic variation; Vmp lipoprotein; Rosetting;

    Abstract : The spirochete Borrelia hermsii avoids the immune response of its mammalian host through multiphasic antigenic variation. Serotype specificity is determined by Variable major proteins (Vmp), in the outer membrane. READ MORE

  2. 2. Streptococcal M protein and human C4BP

    University dissertation from Department of Laboratory Medicine, Lund University

    Author : Jenny J Persson; Lunds universitet.; Lund University.; [2006]
    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

  3. 3. Interactions of human C4BP with Bordetella pertussis and Streptococcus pyogenes

    University dissertation from Department of Medical Microbiology, Lund University

    Author : Karin Berggård; Lunds universitet.; Lund University.; [2001]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; M protein; antigenic variation; phagocytosis resistance; complement; C4b-binding protein C4BP ; Bordetella pertussis; Streptococcus pyogenes; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Abstract : Popular Abstract in Swedish För att skydda sig mot infektioner har människan ett välutvecklat immunförsvar. I immunförsvaret ingår många olika celler och proteiner (äggviteämnen). READ MORE

  4. 4. Antigenic variation in Plasmodium falciparum : understanding the RIFIN protein family

    University dissertation from Stockholm : Karolinska Institutet, Department of Microbiology, Tumor and Cell Biology

    Author : Nicolas Joannin; Karolinska Institutet.; Karolinska Institutet.; [2010]

    Abstract : RIFIN proteins are variable surface antigens, which have a central role in the survival and virulence of the malaria parasite Plasmodium falciparum. Antigenic variation is a mean for these parasites to avoid clearance by the host s immune system. However, this is often a secondary function to the main role of these proteins. READ MORE

  5. 5. Comparative Cell Biology in Diplomonads

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Elin Einarsson; Uppsala universitet.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Giardia intestinalis; Spironucleus salmonicida; intestinal parasite; hydrogenosome; encystation; gene regulation; transfection; diplomonad; antigenic variation; annexin;

    Abstract : The diplomonads are a diverse group of eukaryotic flagellates found in microaerophilic and anaerobic environments. The most studied diplomonad is the intestinal parasite Giardia intestinalis, which infects a variety of mammals and cause diarrheal disease. READ MORE
