  2. 1. Defense-peptides against mycobacteria

    Author : Charlotte M A Linde; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Antimicrobial peptides; NK-lysin; granulysin; PR-39; Mycobacterium;

    Abstract : Several members of the genus Mycobacterium can cause serious infections in both man and animal. One of the world's most serious infectious diseases, tuberculosis, is caused by the pathogen Mycobacterium tuberculosis. Specific defense to tuberculosis/mycobacteriosis is dependent on the individual's ability to mount a proficient immune response. READ MORE

  4. 2. Isolation, structure and processing of bioactive peptides

    Author : Valentina Bonetto; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Amino acid sequences deduced from DNA sequences do not prove in which forms proteins, peptides and their processed products are present in the tissues. The products of a single gene may give rise to variants of peptides because of post-transcriptional or post-translational processing. READ MORE

  5. 3. Early induced immune responses : regulation of dendritic cell and NK cell functions

    Author : Robert Wallin; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Dendritic cell; Natural killer cell; Cytoskeleton; cAMP; cytotoxicity;

    Abstract : The evolution of the advanced vertebrate adaptive immune system has required co-evolution of sophisticated immune regulating systems that determine immune class of cytokines, antibodies as well as effector mechanisms used by killer cells. The co-ordination of these responses are likely to be carried out by dendritic cells (DC) under the influence of the tissue cells and innate immune cells resident in the tissue from where the DC originates.

  6. 4. Isolation and characterization of regulatory peptides and bioactive compounds

    Author : Åke Norberg; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Isolation of peptides and other bioactive compounds is an important and often necessary step to get the total information about their structures. This is demonstrated by a number of different characterizations in this thesis. READ MORE

  7. 5. Pulmonary surfactant proteins B and C : molecular organisation and involvement in respiratory disease

    Author : Shahparak Zaltash; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Lung surfactant is a complex mixture of phospholipids and proteins with the main function to reduce the surface tension at the alveolar air/liquid interface. Surfactant protein B (SP-B) and C (SP-C) are hydrophobic but unrelated in structure, and probably have unique functional roles in the formation of the surface-active monolayer. READ MORE
