Leukocyte-derived matrix metalloproteinase-9 in patients with coronary artery disease
Inflammation is closely associated with development of atherosclerosis. The proteolytic enzyme matrix metalloproteinase (MMP)-9 is considered to play a prominent role in this process. MMP-9 has also been introduced as a marker for plaque vulnerability. Still, the possible mechanisms behind altered levels of MMP-9 and its tissue inhibitors (TIMPs) in patients with atherosclerotic disease remain unclear. The general aim of this thesis was to compare leukocyte-derived MMP-9 and TIMPs in patients with coronary artery disease (CAD) and healthy controls and to further relate the findings to psychological stress and glucocorticoid sensitivity. Levels of leukocyte-derived MMP-9 and TIMP-1 showed a s...
Conformational Changes during Potassium-Channel Gating
Voltage-gated ion channels have a paramount importance in many physiological processes such as cell-to-cell communication, action potential-propagation, and cell motility. Voltage-gated ion channels are characterized by their ability to sense membrane voltage and to greatly change channel activity in response to small changes in the voltage. The ability to sense voltage resides in the four voltage-sensor domains (VSDs) surrounding the central ion-conducting pore. Membrane depolarization causes the inside of the membrane to become positively charged, electrostatically repelling the positively charged fourth transmembrane segment (S4), or voltage sensor, in the VSD, causing the voltage sensor ...
Pro- and anti-inflammatory actions in coronary artery disease
¨The atherosclerotic process is considered to be driven by an imbalance between proand anti-inflammatory actions. Still, the inflammatory state in patients with coronary artery disease (CAD) remains to be clarified. Annexin A1 (AnxA1) is a glucocorticoidinduced protein which may have a key role in the anti-inflammatory response as a mediator of glucocorticoid effects. The general aim of this thesis was to deepen the knowledge of pro- and antiinflammatory mechanisms in CAD via phenotypic assessments of immune cell subsets, in particular CD56+ T cells, and exploration of AnxA1. The long-term goal is to reveal basic mechanisms that will lead to the development of biomarkers, which may be used ...
