Objective:
To review the research progress on protease-activated receptor 2 (PAR-2) in the pathogenesis of osteoarthritis (OA).
Methods:
The relevant literature about the mechanism of PAR-2 in the occurrence and development of OA in recent years was extensively reviewed and comprehensively analyzed.
Results:
Abnormal activation of PAR-2 plays an important role in responses to occurrence and development of OA. Through regulating production and releasing of a variety of cytokines (such as inflammatory factors, metabolic factors, pain factors, etc.), the PAR-2 can involve in pathophysiological progression of OA articular cartilage, subchondral bone, and synovial membrane, as well as occurrence and transmission of pain.
Conclusion:
PAR-2 participation in the development of OA has been confirmed. However, since PAR-2 is complicated and widespread, it is necessary to study the specific role of PAR-2 and the interaction between various signal pathways in the progression of OA, and to elucidate the potential pathophysiological mechanisms of PAR-2 participating in the process of OA, in the hope of exploring the new targets for the effective control of OA.
Insights
Protease-activated receptor 2 (PAR-2) is implicated in osteoarthritis (OA) pathogenesis. Understanding PAR-2
Area of Science:
- Rheumatology
- Molecular Biology
- Pathophysiology
Background:
- Osteoarthritis (OA) is a degenerative joint disease.
- Protease-activated receptor 2 (PAR-2) is a G protein-coupled receptor involved in inflammation and pain.
Purpose of the Study:
- To review research on PAR-2's role in osteoarthritis pathogenesis.
- To analyze the mechanisms of PAR-2 in OA development.
Main Methods:
- Extensive literature review.
- Comprehensive analysis of recent research on PAR-2 in OA.
Main Results:
- Abnormal PAR-2 activation is crucial in OA development.
- PAR-2 regulates cytokines involved in OA progression (cartilage, bone, synovium).
- PAR-2 influences pain occurrence and transmission in OA.
Conclusions:
- PAR-2's involvement in OA is confirmed.
- Further research is needed on specific PAR-2 roles and pathway interactions.
- Elucidating PAR-2 mechanisms may reveal new OA therapeutic targets.

In this pathway, the target proteins are first tagged with small proteins called ubiquitin. A series of enzymes carry out the ubiquitination of the target proteins - E1 (ubiquitin-activating enzyme), E2 (ubiquitin-conjugating enzyme), and E3...
