Entzündungssyndrom: Oxidativer Stress ein gemeinsamer Nenner systemischer Erkrankungen und dessen Folgen für den Schwefelstoffwechsel
Thilo M. Messerschmitt Zusammenfassung Abstract The Inflammation Syndrome: Reactive Oxygen Species a Signal Common to Systemic Diseases and Consequences to the Sulfur Metabolism The formation of Reactive Oxygen Species (ROS) is part of inflammation processes. The ROS are formed by oxidation processes catalysed by iron- and copper-ions. These catalytic processes lead to a change of the cellular redox potential and an accelerated catabolic oxidation of cysteine derived molecules, which are essential for the redox driven energy and signal transport. The result is an irreversible loss of redox active sulfur. Mechanisms for thiol homoeostasis activate methionine transformation to cysteine with the consequence of hyperhomcysteinemea and hypermethylation. These parameters are in direct correlation to atherosclerosis and cancer formation. Acetylcysteine as source of cysteine and redox active thiol interrupts this chain of metabolic processes related to inflammation at various stages and thus helps to protect and restore cell viability.
