  1. 1. Variability and adaptation in the contractile system of smooth muscle

    Författare :Mia Löfgren; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; essential light chain; desmin; shortening velocity; integrin; intermediate filament; hypertrophy; non-muscle myosin; smooth muscle; myosin; heavy chain; Physiology; Fysiologi;

    Sammanfattning : This thesis examines the cellular and molecular mechanisms involved in the large diversity of the contractile properties in smooth muscle. Six studies, I-VI, are included. I: a slow smooth muscle (aorta) has a different nucleotide and phosphate dependence compared to a fast type (taenia coli). LÄS MER

  2. 2. Developmental regulation of smooth muscle contraction in the urinary bladder

    Författare :Mari Ekman; Cellulär biomekanik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; newborn; Rho-kinase; cellular signaling; muscarinic receptors; calcium sensitivity; protein kinase C; non-muscle myosin; myosin light chain phosphatase;

    Sammanfattning : Smooth muscle cells in the urinary bladder are involved in the control of urine filling and emptying. We have used mice to study the contractile regulation of urinary bladder smooth muscle during the fetal period. LÄS MER

  3. 3. Function of contractile and cytoskeletal proteins in smooth muscle: Effects of hypertrophy and age and desmin removal in a transgenic animal

    Författare :Rolf Sjuve; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; transgenic mouse; desmin; embryonic myosin; isoforms; myosin heavy chain; age; smooth muscle; hypertrophy; Physiology; Fysiologi;

    Sammanfattning : In man, the urinary bladder responds to an urinary outflow obstruction with a pronounced dilatation and growth of the bladder wall. This clinical situation can be mimicked in rat by creation of a partial urinary outflow obstruction and the papers included in the present thesis use this animal model to address questions regarding the adaptive changes in the smooth muscle of the growing bladder.

  4. 4. Molecular and microscopical analysis of pathogenic streptococci - studies on surface proteins interacting with human cells and extracellular matrix

    Författare :Marta Bober; Infektionsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Streptococcus pyogenes; streptococcal leucine rich repeat protein; M protein; collagen; keratinocytes;

    Sammanfattning : Association to specific host tissue structures allows pathogenic bacteria to establish an infection and facilitates the spread within its host. Interactions between bacterial surface structures and human proteins might determine the outcome of the infection. Streptococcus pyogenes (S. LÄS MER

  5. 5. Cell motility : the dynamics of the cortical weave of microfilaments and its relation to microtubules and coated vesicles in fibroblasts and glial cells

    Författare :Anna-Stina Höglund; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : Actin and myosin, the major components of the microfilament system are found in most - if not all - eukaryotic cells. In muscle they form the basis of the contractile apparatus which generates the rapid, strong and unidirectional movements that characterizes muscle activity. LÄS MER
