The role of matrix metalloproteinases in osteoarthritis pathogenesis: An updated review

Publication date: Available online 22 August 2019Source: Life SciencesAuthor(s): Mehana E. El-Sayed, Khafaga F. Asmaa, El-Blehi S. SamarAbstractExtensive degeneration of articular cartilage (AC) is a primary event in the pathogenesis of osteoarthritis (OA) and other types of joint and bone inflammation. OA results in the loss of joint function, usually accompanied by severe pain, and are the most common type of arthritis, affecting more than 10% of adults. The characteristic signs of OA are progressive cartilage destruction and, eventually, complete loss of chondrocytes. A key enzyme responsible for these degenerative changes in cartilage is matrix metalloproteinase-13 (MMP-13), which is thought to be a major contributor to the degenerative process occurring during OA pathogenesis. The aim of the present review is to shed light on the general role of MMPs, with special emphasis on MMP-13, in the induction of OA and the general basis of OA treatment. The pathogenic mechanism of this highly prevalent disease is not clear, and no effective disease-modifying treatment is currently available. Any updated information about OA treatment in human patients will also benefit companion animals such as horses and dogs, which also suffer from OA. Selective inhibition of MMP-13 seems to be an attractive therapeutic strategy.Graphical abstract

Objective The aim of the study was to assess the time effect of intra-articular injection with triamcinolone hexacetonide in rheumatic patients. Design A prospective case-control study with patients submitted to one intra-articular injection with triamcinolone hexacetonide. Patients were followed monthly (12 mos) for pain and swelling. Results Two hundred sixty-two joints were assessed in 158 patients with mean ± SD age of 60 ± 13.7 yrs. Remission was observed at 3, 6, and 12 mos in 142 (54.19%), 111 (42.36%), and 105 (40.07%) joints, respectively. The mean ± SD time effect were 8 ± 4.0 ...

Our body is flexible due the joints. These joints connect two bones, provide support and help in the body parts movement. Joint pain is a feeling of discomfort, aches and soreness in any of our body ’s joint. There have been lots of cases of people having aches in their joints. These joint pains are due to injuries affecting the ligaments, bursae, or tendons surrounding the joint. Pain in the joints is also due to infection and inflammation and in an extremely rare case because of cancer. It becomes extremely painful when you try to move your body parts suffering this pain.There are different conditions which are res...

Medicinal agents, exclusively nonsteroidal anti-inflammatory drugs (NSAIDs), have been routinely applied in the clinic. But, their effects are restricted to pain control with insignificant effects on cartilage renovation, which would finally lead to cartilage destruction. In the field of regenerative medicine, ...

AbstractRheumatoid arthritis (RA) is a systemic, autoimmune disease that affects joints and extra-articular structures. In the last decade, the management of this chronic disease has dramatically changed with the introduction of several targeted mechanisms of action, such as tumor necrosis factor- α inhibition, T-cell costimulation inhibition, B-cell depletion, interleukin-6 blockade, and Janus kinase inhibition. Beyond its well-known hematopoietic role on the proliferation and differentiation of myeloid cells, granulocyte-monocyte colony-stimulating factor (GM-CSF) is a proinflammatory medi ator acting as a cytokine...
