Sammanfattning : The muscle fibre cytoskeleton of skeletal and heart muscle cells is composed mainly of intermediate filaments (IFs), that surround the myofibrils and connect the peripheral myofibrils with the sarcolemma and the nuclear membrane. Desmin is the first muscle specific IF protein to be produced in developing muscles and is the main IF protein in mature muscles. LÄS MER
2. Function of contractile and cytoskeletal proteins in smooth muscle: Effects of hypertrophy and age and desmin removal in a transgenic animal
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.

Sammanfattning : We have examined the functional and structural roles of the cytoskeletal protein desmin in cardiac and skeletal muscles using a genetically modified mouse (Des-/-) with the desmin gene ablated. Desmin forms filaments at the Z-disks in the striated muscle sarcomere, have connections to the sarcolemma and most likely align sarcomeres and whole cells. LÄS MER
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
5. Neuromuscular injuries and pharyngeal dysfunction in snorers and sleep apnea patients : a study on pathological changes in the human soft palate and its relationship with swallowing dysfunction
Sammanfattning : Obstructive sleep apnea (OSA) is a prevalent progressive sleep disorder with serious negative health consequences. Although several risk factors such as obesity can make an individual vulnerable to develop OSA, the pathophysiological mechanism for the collapse of the upper airway is unclear. LÄS MER
