  1. 1. Protein–DNA Recognition In Vitro Evolution and Characterization of DNA-Binding Proteins

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Mikael Nilsson; Mikael Widersten; Dan Tawfik; [2004]

    Sammanfattning : DNA-recognizing proteins are involved in a multitude of important life-processes. Therefore, it is of great interest to understand the underlying mechanisms that set the rules for sequence specific protein–DNA interactions. Previous attempts aiming to resolve these interactions have been focused on naturally occurring systems. LÄS MER

    Sammanfattning : The three evolutionarily related peptides neuropeptide Y (NPY), peptide YY (PYY) and pancreatic polypeptide (PP) are ligands to at least five G-protein coupled receptors in mammals, which are denoted by numbers. NPY has many physiological effects including stimulation of appetite and regulation of circadian rhythm and blood pressure. LÄS MER

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

    Detta är en avhandling från Department of Immunotechnology, Lund University

    Författare :Nina Nilsson; [2000]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; B cell development and phage display; transplantation; serology; Immunology; Immunologi; serologi; Biology; Biologi;

    Sammanfattning : 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. LÄS MER

  4. 4. Evolution of olfaction in Lepidoptera and Trichoptera : Gene families and antennal morphology

    Detta är en avhandling från Lund University, Faculty of Science, Department of Biology

    Författare :Jothi Kumar Yuvaraj; [2017-10]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; evolution; pheromone receptors; olfaction; chemosensory; sensillum; HEK 293 cells;

    Sammanfattning : In moths, females produce sex pheromone compounds to attract males over a long distance for mating. The antennae of moths and many other insects have specialized odorant receptors (ORs), called pheromone receptors (PRs), to sense the pheromone compounds and they group in a monophyletic clade (PR clade).

  5. 5. Toll-like Receptors in Airway Inflammation in vitro and in vivo

    Detta är en avhandling från Stockholm : Karolinska Institutet, Institute of Environmental Medicine

    Författare :Ida von Schéele; Karolinska Institutet.; Karolinska Institutet.; [2011]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : During evolution a variety of solutions has been developed by different living organisms in order to protect itself from invading potential pathogens and particles. Protection of the host is essential for its survival and involves efficient recognition and elimination of potential pathogens. LÄS MER
