    University dissertation from Paediatrics, Faculty of Medicine, Lund University

    Author : Ida Arvidsson; Lunds universitet.; Lund University.; [2015]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; EHEC; hemolytic uremic syndrome; Shiga toxin; complement; hemolysis; microvesicles; cathelicidin;

    Abstract : Popular Abstract in Swedish Enterohemorragisk Escherichia coli (EHEC) EHEC är mycket virulent för människor, det räcker med så få som 50-100 bakterier för att man ska bli infekterad och utveckla symtom. Varje år rapporteras ca 300-500 fall av EHEC smitta i Sverige. Den stam som oftast isoleras från patienter är E. coli O157:H7. READ MORE

  2. 2. Functional dualism of antimicrobial host defence peptides

    University dissertation from Paediatrics, Faculty of Medicine, Lund University

    Author : Åse Björstad; Göteborgs universitet.; Gothenburg University.; [2009]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; antimicrobial; apoptosis; cathelicidin; host defence peptide; interleukin 8; LL-37; permeabilisation;

    Abstract : Antimicrobial host defence peptides are central to innate immunity and many possess direct antimicrobial actions on bacteria as well as indirect immunomodulatory functions on human leukocytes. Different variants of the bifunctional Helicobacter pylori peptide, Hp(2-20), were synthesised and inhibition zone assays and chemiluminescence systems were employed for determination of direct antimicrobial action and superoxide release (immunomodulatory) from human neutrophils, respectively.

  3. 3. Expression of cathelicidin antimicrobial peptides in man and rat

    University dissertation from Stockholm : Karolinska Institutet, Microbiology and Tumor Biology Center (MTC)

    Author : Stefan Termén; Karolinska Institutet.; Karolinska Institutet.; [2004]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; LL-37; rCRAMP; butyrate; colonic epithelium; central nervous system; transcription;

    Abstract : Endogenous antimicrobial peptides are effectors of innate immunity. They kill microorganisms by disrupting their cell membranes, but are also believed to have signaling functions in the immune system. They are present in epithelia, secretions and phagocytic cells. READ MORE

  4. 4. Studies of the role of the cathelicidin peptide LL-37 in epithelial biology

    University dissertation from Stockholm : Karolinska Institutet, Department of Medicine

    Author : Clara Ibel Chamorro Jimenez; Karolinska Institutet.; Karolinska Institutet.; [2010]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : The biology of epithelial immunity as well as of tissue repair is complex and highly regulated. A variety of molecules, cell types, and biological processes such as, cell differentiation, proliferation and migration, programmed cell death and antimicrobial mechanisms contribute to maintaining a balance between tissue damage and tissue repair.
