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

7. Dynamics of Ca2 handling in vascular smooth muscle
Abstract : Intracellular Ca2+ is a key regulator of vascular contractility, and thereby of blood perfusion and pressure. Ca2+ signals are essential also for cell migration, proliferation and regulation of numerous enzymes. READ MORE

8. Modulaton of gene expression in human aortic smooth muscle cells by Porphyromonas gingivalis : a possible association between periodontitis and atherosclerosis
Abstract : Porphyromonas gingivalis is a gram-negative, rod-shaped, and anaerobic bacterium that is involved in the pathogenesis of periodontitis. P. gingivalis produces a variety of virulence factors including gingipains and fimbriae. READ MORE

9. Signal transduction and calcium sensitivity of smooth muscle contraction
Abstract : Smooth muscles are components of several physiologically important organs and often involved in disease. Smooth muscle contraction is regulated by variations in intracellular [Ca2+]; increased levels activate the myosin light chain kinase (MLCK) which phosphorylates myosin and initiates contraction.

10. Phenotypic modulation of vascular smooth muscle in organ culture
Abstract : Contraction of blood vessels for the regulation of blood flow and pressure is dependent on vascular smooth muscle cells (VSMC) located in the medial layer of the vascular wall. Adult, differentiated VSMC have a well developed contractile system and a low rate of proliferation. READ MORE
