  2. 11. Isoform-specific regulation of Drosophila gut immunity and regeneration by the POU/Oct transcription factor Nub/Pdm1

    Author : Xiongzhuo Tang; Ylva Engström; Tony Ip; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; POU; Nubbin; Drosophila; intestinal stem cell; epithelium regeneration; midgut; mitosis; Antimicrobial peptides; innate immunity; NF-κB; bacterial infection; transcriptional regulation; homeostasis; Molecular Biology; molekylärbiologi;

    Abstract : Innate immune reactions protect organisms against a variety of infections.  In metazoans, these reactions involve both cellular and humoral responses. The immune responses have to be well-tuned, as excessive immune activation is associated with tissue-specific pathologies. READ MORE

  4. 12. Signaling and transcriptional regulation of antimicrobial peptide genes in Drosophila melanogaster

    Author : Hanna Uvell; Ylva Engström; Won-Jae Lee; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; antimicrobial peptides; drosophila; immunity; transcriptiona regulation; Molecular biology; Molekylärbiologi;

    Abstract : Insects rely solely on innate immune reactions for protection against infect-ing microbes in their environment. In Drosophila, one major defense mechanism is the production of a battery of antimicrobial peptides (AMPs). READ MORE

  5. 13. Structural and Functional Studies of De Novo Designed Peptides at Surfaces

    Author : Patrik Nygren; Bo Liedberg; Thomas Ederth; Martin Malmsten; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biofouling; vesicles; nanoparticles; peptide; peptide design; circular dichroism; Physical chemistry; Fysikalisk kemi;

    Abstract : The work presented in this thesis deals with the structural and functional properties of peptides at surfaces. The interaction of peptides with surfaces is an ever so common occurrence in our every day life, from the bug squashed on the windshield of our car to the barnacle on our boat, and from the blood plasma used in the hospital to the proteins in our cells.

  6. 14. Regulatory proteins and the regulation of immune response in Drosophila melanogaster

    Author : Erik Roos; Åsa Rasmuson-Lestander; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; Molekylärbiologi; Molecular Biology; molekylärbiologi;

    Abstract : Insect antibacterial peptides are regulated at the transcriptional level. The otherwise silent antibacterial Cecropin genes are strongly induced upon bacterial challenge. READ MORE

  7. 15. The human antimicrobial protein hCAP18/LL37 in wound healing and cell proliferation

    Author : Johan Heilborn; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Innate immunity; antimicrobial peptides; LL-37; epithelial cell; keratinocytes; proliferation; reepithelialization; wound healing; tissue repair; angiogenesis; tumor growth; vitamin D;

    Abstract : Epithelia constitute the principal barriers separating the host and the potentially injurious environment, and defence of this interface is therefore essential. Antimicrobial peptides are key effector molecules of the innate immune system. READ MORE
