Exosomes in Osteoarthritis: Emerging Roles in Pathogenesis, Diagnosis, and Therapeutic Potential

Area of Science:

• Biomedical research
• Regenerative medicine
• Osteoarthritis research

Background:

• Osteoarthritis (OA) is a prevalent degenerative joint disease causing pain and disability, with limited treatment options.
• Current OA management focuses on symptomatic relief, highlighting the need for disease-modifying therapies.
• Exosomes, crucial for intercellular communication, are emerging as key players in OA pathogenesis and potential therapeutic targets.

Purpose of the Study:

• To review the current understanding of exosome roles in osteoarthritis.
• To explore the diagnostic and therapeutic potential of exosomes in OA.
• To discuss exosome-based drug delivery systems and future research directions for OA treatment.

Main Methods:

• Comprehensive literature review of studies on exosomes and osteoarthritis.
• Synthesis of evidence on exosome-mediated cellular processes in OA.
• Analysis of exosomal non-coding RNAs (ncRNAs) in cartilage degradation and bone remodeling.

Main Results:

• Mesenchymal Stem Cell (MSC)-derived exosomes influence chondrocyte behavior, including proliferation, apoptosis, autophagy, and inflammation.
• Exosomal ncRNAs (miRNAs, lncRNAs, circRNAs) are implicated in regulating cartilage breakdown and subchondral bone changes in OA.
• Exosomes demonstrate dual potential as biomarkers for OA diagnosis and as therapeutic agents.

Conclusions:

• Exosomes represent a promising avenue for novel OA diagnostic and therapeutic strategies.
• Exosome-based drug delivery systems (DDSs) offer a targeted approach for OA treatment.
• Further research into exosome technology integration is crucial for advancing OA regenerative medicine.
