  1. 1. Statins, Lipids, and Mutations: Consequences for the Heart and Immune System

    University dissertation from Göteborgs universitet

    Author : Emil G. Ivarsson; Göteborgs universitet.; Gothenburg University.; [2019]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CAAX Proteins; Statins; RHO Proteins; Dilated Cardiomyopathy;

    Abstract : CAAX proteins are a group of proteins that undergo a three-step protein maturation process that renders the proteins carboxyl-terminus hydrophobic and prone to localize to cellular membranes, where they have their primary function. The first step in this process is called prenylation, which is the covalent attachment of a lipid, either a 15-carbon farnesyl or a 20-carbon geranylgeranyl lipid, to the carboxyl-terminal cysteine residue by the enzymes farnesyltransferase (FTase) and geranylgeranyltransferase type I (GGTase-I), respectively.

  2. 2. Studies of bacterial surface proteins interacting with the immune system

    University dissertation from Henrik G. Svensson, BMC B14, Tornavägen 10, 22184 Lund, Sweden

    Author : Henrik G Svensson; [2002]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bakteriologi; Mikrobiologi; virologi; mykologi; Microbiology; bacteriology; virology; mycology;

    Abstract : Pathogenic bacteria express a wide array of surface proteins that interact with the environment. Many of these proteins are believed to be important for the virulence. This thesis deals with the binding of immunoglobulins (Ig) and complement regulating proteins to certain bacterial surface proteins. READ MORE

  3. 3. Studies on Pellicle and Early Dental Plaque in Relation to Periodontal Conditions

    University dissertation from Henrik G. Svensson, BMC B14, Tornavägen 10, 22184 Lund, Sweden

    Author : Stefan G Rüdiger; Göteborgs universitet.; Gothenburg University.; [2012]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bacterial adherence; in vitro pellicle; in vivo pellicle; periodontitis-associated bacteria; gingival crevicular fluid; plasma proteins; dental biofilm; experimental gingivitis; chronic periodontitis; periodontal pocket; exposed root surfaces;

    Abstract : Background and Hypothesis: Bacterial receptors in dental pellicles may influence colonisation and subsequent plaque formation. Studies on such receptors in the dental pellicles and bacterial adherence have mostly been performed in vitro and focused on proteins of salivary origin. READ MORE

  4. 4. On the role of plasma proteins in bacterial adhesion to dental surfaces

    University dissertation from Henrik G. Svensson, BMC B14, Tornavägen 10, 22184 Lund, Sweden

    Author : Stefan G Rüdiger; Göteborgs universitet.; Gothenburg University.; [2003]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Bacterial receptors in dental pellicles could influence colonisation and subsequent plaque formation. Studies of such receptors in dental pellicles and bacterial adherence have often focused on proteins of salivary origin. We have only a limited knowledge of the receptor functions of plasma proteins reaching the pellicle via the crevicular fluid. READ MORE

  5. 5. The Role of RNA Binding Proteins in Insulin Messenger Stability and Translation

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Rikard G. Fred; Nils Welsh; Michele Solimena; [2010]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICINE Morphology; cell biology; pathology Cell biology Medical cell biology; MEDICIN Morfologi; cellbiologi; patologi Cellbiologi Medicinsk cellbiologi; Medical Cell Biology; Medicinsk cellbiologi;

    Abstract : Although the reason for insufficient release of insulin in diabetes mellitus may vary depending on the type and stage of the disease, it is of vital importance that an amplified insulin biosynthesis can meet the increased need during periods of hyperglycemia. The insulin mRNA is highly abundant in beta cells and changes in insulin mRNA levels are, at least in part, controlled by altered rates of mRNA degradation. READ MORE
