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

    Author : Mia Löfgren; Institutionen för experimentell medicinsk vetenskap; []
    Keywords : 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;

    Abstract : 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). READ MORE

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

    Author : Mari Ekman; Cellulär biomekanik; []
    Keywords : 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;

    Abstract : 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. READ MORE

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

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

    Abstract : 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.

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

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

    Abstract : 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. READ MORE

  7. 5. Cell motility : the organization of the microfilament system in cultured cells with special emphasis on the cortical weave of actin filaments

    Author : Roger Karlsson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The microfilament system formed by actin, myosin and associated proteins constitutes the molecular basis for many of the motile phenomena which eukaryotic cells express. The organization of this system varies considerably from cell type to cell type, and is characterized on one hand by strictly ordered, more or less flexible arrangements of actin filaments and on the other by actin present in primarily a nonfilamentous form ready to polymerize in response to certain stimuli.
