Progress in the study of damage-associated molecular patterns as intrinsic drivers involved in the process of osteoarthritis
Osteoarthritis(OA),as a common degenerative disease in the middle-aged and elderly population,has long been plagued by its persistent nature,leading to a series of problems such as increasing medical consumption and declining quality of life.At present,the treatment plans for OA mainly focus on improving the inflammatory pain inside the joints,and there is no effective cure.Related literature indicates that the activation of macrophages and the initiation of inflammatory cascade reactions are closely related to the colonization of damage-associated molecular patterns(DAMP).DAMP,as a driving agent,plays a crucial role in the chronic inflammatory process of joints.They not only exist in internal joint injuries,but also can be released into the bloodstream to participate in external joint inflammatory processes.The inflammatory induction of DAMP inside and outside the joint can serve as an important driving force in the progression of OA.This article will start with DAMP and explore the positive feedback regulation mechanism of DAMP-related chronic joint inflammation,as well as the mediating role of DAMP in the inflammatory microenvironment outside the joints of OA patients.
