Abstract:
BACKGROUND:In addition to apoptosis,recent studies have discovered novel forms of programmed cell death in periprosthetic osteolysis,which is involved in regulating local chronic inflammation and the outcome of osteoblast and osteoclast under pathological conditions.This has an important value for the treatment and prognosis of periprosthetic osteolysis. OBJECTIVE:To provide new ideas and strategies for the prevention and treatment of periprosthetic osteolysis by summarizing studies on the novel forms of programmed cell death. METHODS:The first author used the computer to search the articles published from 2005 to 2022.Chinese search terms"wear particles,periprosthetic osteolysis,programmed cell death,apoptosis,autophagy,pyroptosis,necrotizing apoptosis,iron death"were used to search the databases of CNKI,WanFang and VIP.English search terms"osteolysis,wear debris,wear particles,peri*prosthetic osteolysis,PPOL,aseptic loosening,autophagy,regulated cell death,programmed cell death,apoptosis,pyroptosis,autophagic cell death,autophagy,necroptosis,ferroptosis"were used for search in PubMed and Web of Science databases.A total of 68 articles were finally included according to the inclusion criteria. RESULTS AND CONCLUSION:(1)Inadequate or excessive activation of autophagy can cause cell death,inhibit bone formation,and promote bone resorption,leading to bone metabolism disorders and osteolysis.(2)Recent studies have paid close attention to pyroptosis in periprosthetic osteolysis,where the Nod-like receptor,pyrin containing 3 inflammasome plays an important role in local inflammation.Inhibiting pyroptosis can effectively alleviate osteolysis.(3)In vitro studies have shown that necroptosis can inhibit the formation and function of osteoblasts and osteoclasts,affecting the process of osteolysis and destruction.(4)Ferroptosis is the newest form of programmed cell death,which is regulated by complex signaling pathways and mechanisms,but is not yet fully understood.(5)Autophagy,pyroptosis,necroptosis,and ferroptosis play important roles in the development of periprosthetic osteolysis,and their associated signaling pathways and genes require further investigation.
