Necroptosis in pathogenesis of osteoarthritis and its therapeutic implications.

Abstract

Osteoarthritis is a progressive degenerative joint disease induced by many causes, for which there is no radical cure currently. Necroptosis is a newly reported programmed cell death, and its related factors are also inseparable from the progress of osteoarthritis. For examples, damage-associated molecular pattern promotes the release of various inflammatory factors, so as to recruit macrophages and promote local inflammation of the joint; inhibition of receptor-interacting protein kinase can reduce the death of cell and the expression of inflammatory factors, so as to reduce cartilage damage. Therefore, in-depth study of the regulatory mechanism of necroptosis in osteoarthritis will help to further reveal the pathogenesis of osteoarthritis, so as to provide potential targets for the treatment of osteoarthritis.
