Targeting Cell Death: Pyroptosis, Ferroptosis, Apoptosis and Necroptosis in Osteoarthritis

Area of Science:

• Biomedical science
• Molecular biology
• Immunology

Background:

• Osteoarthritis (OA) pathogenesis is complex, involving inflammatory processes.
• Cytokines play a crucial role in regulating cellular responses in OA.
• Different programmed cell death pathways are implicated in OA development.

Purpose of the Study:

• To review the pathogenesis of osteoarthritis (OA) in relation to cytokine-triggered cell death.
• To elucidate the molecular mechanisms linking cytokines and cell death in OA.
• To provide a comprehensive overview of current research on cell death and OA.

Main Methods:

• Literature review of existing research on OA, cytokines, and cell death.
• Analysis of molecular mechanisms and morphological features of pyroptosis, apoptosis, necroptosis, and ferroptosis.
• Synthesis of findings on the interplay between different cell death types and OA progression.

Main Results:

• Osteoarthritis development is regulated by distinct cell death mechanisms and cytokine types.
• Pyroptosis, apoptosis, necroptosis, and ferroptosis exhibit unique morphological and molecular characteristics relevant to OA.
• Specific molecular pathways link various cytokines to these cell death modalities in the context of OA.

Conclusions:

• Elucidating the mechanisms of action among cytokines, cell death processes, and OA is crucial for understanding disease pathogenesis.
• Targeting specific cytokine-cytotoxicity interactions may offer novel therapeutic strategies for OA.
• Further research is needed to fully define the role of each cell death pathway in OA progression.
