  1. 1. The biology of filamentous phage infection - implications for display technology

    Author : Fredrik Karlsson; Institutionen för immunteknologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biotechnology; Bioteknik; infection mechanism; selective infection; TolA; Escherichia coli; pIII; Filamentous phage; Phage display technology;

    Abstract : Phage display technology is a biotechnological tool that can be used to obtain molecules/reagents able to discriminate between target molecules. Reagents with such features can be used in diverse settings like biological chemistry, diagnostics and in therapeutic applications. READ MORE

  2. 2. In vivo and in vitro evolution of molecular mechanisms - Importance in B cell development and phage display

    Author : Nina Nilsson; Institutionen för immunteknologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; B cell development and phage display; transplantation; serology; Immunology; Immunologi; serologi; Biology; Biologi;

    Abstract : Bone marrow resident hematopoietic stem cells differentiate into all different types of lymphoid populations, there among mature naive B cells expressing IgM and IgD. During the maturation, the B cells are subjected to several steps of selection to ensure proper development of the antigen receptor. READ MORE

  3. 3. Effects of Vibrio cholerae protease and pigment production on environmental survival and host interaction

    Author : Karolis Vaitkevicius; Sun Nyunt Wai; Timo Korhonen; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bacteria-host interaction; Nematode; Metalloprotease; Medical microbiology; Medicinsk mikrobiologi;

    Abstract : Only two out of more than 200 V. cholerae serogroups, classified on the basis of LPS structure, are associated with epidemic or pandemic cholera. These toxigenic serogroups carry phage-derived pathogenicity islands coding for the main virulence factors for establishment of cholera disease – cholera toxin (CTX) and toxin-coregulated pilus (TCP).

  4. 4. Modulators of Vibrio cholerae predator interaction and virulence

    Author : Barbro Lindmark; Sun Nyunt Wai; Kristian Riesbeck; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Vibrio cholerae; Caenorhabditis elegans; PrtV; outer membrane vesicles; non-O1 non-O139; serum resistance; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Abstract : Vibrio cholerae, the causal agent of cholera typically encodes two critical virulence factors: cholera toxin (CT), which is primarily responsible for the diarrhoeal purge, and toxin-co-regulated pilus (TCP), an essential colonisation factor. Nontoxigenic strains expressing TCP can efficiently acquire the CT gene through lysogenic conversion with CTXΦ, a filamentous phage that encodes CT and uses TCP as a receptor. READ MORE

  5. 5. Humoral immunity during primate lentivirus infection : evaluation of B cell apoptosis and engineering of virus specific antibodies

    Author : Astrid Samuelsson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The focus of this project was to evaluate the contribution of the humoral immunity in controlling infection with primate lentiviruses - an area which has implications both for vaccine design as well as for understanding of the pathogenesis of the disease. The first goal was to generate efficient neutralizing reagents which could be used for passive immunotherapy trials, preferably in the macaque system, and to investigate if peptide immunogens could elicit such antibodies.
