1. Filament assembly and structural studies of intermediate filament like protein, FilP, in Streptomyces coelicolor
Sammanfattning : The cytoskeleton, known as intracellular connected filaments, has a prominent role in cellular behavior, motility, and stability. The following three major types of polymers have been characterized as cytoskeleton in eukaryotes: microtubules that are 25 nm in diameter, actin filaments that are 7 nm in diameter, and intermediate filaments (IF) that are 10 nm in diameter.

2. On the mechanics of actin and intermediate filament networks and their contribution to cellular mechanics
Sammanfattning : The mechanical behaviour of cells is essential in ensuring continued physiological function, and deficiencies therein can result in a variety of diseases. Also, altered mechanical response of cells can in certain cases be an indicator of a diseased state, and even actively promoting progression of pathology. LÄS MER
3. Variability and adaptation in the contractile system of smooth muscle
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
4. Role of intermediate filament desmin in development of desmin-related myopathy
Sammanfattning : Desmin is a major intermediate filament of muscle cells, serving to transmit mechanical forces and propagate mechanochemical signals, to coordinate contraction and relaxation cycles, and to stabilize the positioning of cellular organelles, e.g. mitochondria. LÄS MER
5. Nestin : filament formation and expression in myogenesis and muscle disorders
Sammanfattning : Intermediate filaments (IF), together with microfilaments and microtubules, are the major components of the cytoskeleton of eukaryotic cells. In myogenic cells three IF proteins are expressed; desmin, vimentin and nestin. LÄS MER
