Abstract

Osteoarthritis (OA) is a common chronic joint disease characterized by articular cartilage degeneration, subchondral sclerosis, synovitis, and osteophyte formation. OA is associated with disability and impaired quality of life, particularly among the elderly. Leptin, a 16-kD non-glycosylated protein encoded by the obese gene, is produced on a systemic and local basis in adipose tissue and the infrapatellar fat pad located in the knee. The metabolic mechanisms employed by leptin in OA development have been widely studied, with attention being paid to aging as a corroborative risk factor for OA. Hence, in this review, we have attempted to establish a potential link between leptin and OA, by focusing on aging-associated mechanisms and proposing leptin as a potential diagnostic and therapeutic target in aging-related mechanisms of OA that may provide fruitful guidance and emphasis for future research.

Research summary

The paper discusses the role of leptin in osteoarthritis (OA) with a focus on aging, which connects to age-related mechanisms. However, it primarily addresses the symptoms and potential treatment of OA rather than tackling the root causes of aging itself. While it offers insights into a specific aspect of aging-related diseases, its contribution to the broader field of longevity research is limited, making it a solid but not highly impactful study.
