Abstract: BACKGROUND: Recently, it has been discovered that pyroptosis is involved and plays a role in the pathological progress of osteoarthritis.
OBJECTIVE: To understand the latest research progress in the role of cell pyroptosis in osteoarthritis, and to explore their relationship, so as to provide a new target for the research, diagnosis and treatment of osteoarthritis.
METHODS: Relevant literatures were retrieved from databases such as CNKI, WanFang, VIP, ScienceDirect, Nature, Springer, and PubMed. The Chinese and English search terms included osteoarthritis (OA), pyroptosis, nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3), nuclear factor kappa B (NF-κB), caspase, interleukin (IL), and gasdermin D (GSDMD). According to the inclusion criteria, 61 relevant literatures were included for further analysis.
RESULTS AND CONCLUSION: Pyroptosis is certainly related to the degradation of cartilage, inflammation, and synovial damage in osteoarthritis. Some proteins and cytokines involved in the activation of pyroptosis activation are differentially expressed, such as NLRs, caspases, interleukins and GSDMD. Although these proteins and cytokines are known to be involved in the pathological progress of osteoarthritis, their mechanism underlying osteoarthritis has not been completely understood.

Key words: osteoarthritis, pyroptosis, nucleotide-binding oligomerization domain-like receptor protein 3, nuclear factor kappa B, caspase, interleukin, gasdermin D
