[Crystal-induced joint inflammation].
The inflammatory response to microcrystals is one of the most powerful and intriguing examples of inflammation observable in man. Although many mechanisms of this reaction are well known, some aspects need to be further clarified, in particular those related to the self-limited nature of the process. Type and duration of the inflammatory reactions are mainly influenced by crystals characteristi...
متن کاملCrystal-induced Inflammation in Canine Joints
Injection of sodium urate or calcium pyrophosphate crystals into the stifle joints of anesthetized dogs almost invariably induced an acute exudative response. This response was quantified by serial measurements of intra-articular pressure, pH and leukocyte concentration. Pressure rose progressively and reflected intra-articular volume increase. The hydrogen ion concentration increased as the re...
متن کاملMelanocortin 3 receptors control crystal-induced inflammation.
In this study we have characterized the anti-inflammatory profile of a selective melanocortin type 3 receptor (MC3-R) ligand [D-Trp8]-gamma-MSH, validating in vitro results with analyses in mice deficient for this receptor subtype. In wild-type (WT) macrophages, [D-Trp8]-gamma-MSH activated MC3-R (as tested by accumulation of cyclic AMP) and inhibited (approximately 50%) the release of interleu...
متن کاملMetabolic stress-induced joint inflammation and osteoarthritis.
Osteoarthritis (OA) is a heterogeneous disorder with several risk factors. Among them, obesity has a major impact on both loading and non-loading joints. Mechanical overload and activity of systemic inflammatory mediators derived from adipose tissue (adipokines, free fatty acids (FFA), reactive oxygen species (ROS)) provide clues to the increased incidence and prevalence of OA in obesity. Recen...
متن کاملTHE EFFECT OF CARRAGEENAN-INDUCED INFLAMMATION ON BLOOD FLOW IN THE RABBIT KNEE JOINT
Experiments were carried out on anesthetized adult New Zealand rabbits. Acute joint inflammation was achieved by intra-articular injection of 2% carrageenan. Radiolabelled microspheres were used to measure the effect of acute inflammation on blood flow in the knee joint and establish whether neural influences on blood vessel caliber were affected. Surgical exposure of the posterior joint "capsu...
