  2. 11. Cell-penetrating peptides : Uptake mechanism and the role of receptors

    Author : Henrik Helmfors; Ülo Langel; Hanne Mørck Nielsen; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    Abstract : Genes are the major regulators of biological processes in every living thing. Problems with gene regulation can cause serious problems for the organism; for example, most cancers have some kind of genetic component. Regulation of biological processes using oligonucleotides can potentially be a therapy for any ailment, not just cancer. READ MORE

  4. 12. Interactions of chiral ions and molecules in gas phase : Towards an understanding of chiral recognition mechanism

    Author : Oleksii Rebrov; Mats Larsson; Richard Thomas; Vitali Zhaunerchyk; Anne Zehnacker-Rentien; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fysik; Physics;

    Abstract : This thesis comprises the research related to interactions of enantiopure amino acids with chiral and achiral molecules in gas phase. The investigation of the mechanism responsible for chiral discrimination is of the special interest in this work. READ MORE

  5. 13. Stealthy Sensor Attacks on Feedback Systems : Attack Analysis and Detector-based Defense Mechanisms

    Author : David Umsonst; Henrik Sandberg; Hideaki Ishii; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Abstract : In this thesis, we investigate sensor attacks on feedback systems and how anomaly detectors can be used as a defense mechanism. We consider an attacker with access to all sensor measurements and full knowledge about the closed-loop system model. READ MORE

  6. 14. The human antimicrobial peptide hCAP18 in epithelial defense

    Author : Margareta Frohm Nilsson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Innate immunity; host defense; antimicrobial peptide; hCAP 18; LL-37; epithelia; wounds; breast cancer;

    Abstract : Gene-encoded antimicrobial peptides serve a protective role in host defense. They are multifunctional effector molecules in innate immunity - the nonadaptive immune system -with the capacity to kill a broad spectrum of microorganisms. READ MORE

  7. 15. Effects of the host defense peptide LL-37 on human cells : Immunomodulation and cytotoxicity

    Author : Sara Bodahl; Kärlfysiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; LL-37; Host defense peptides; Cathelicidin; Inflammation; Cytotoxicity; TLR3; Poly I:C;

    Abstract : The human host defense peptide LL-37 has an essential role in the first line of defense against invading pathogens. This cathelicidin is mainly produced by immune cells and epithelial cells aligning the mucosal areas and is normally upregulated upon infection and inflammation. READ MORE
