Interleukin-6: Unravelling its role in sarcopenia pathogenesis and exploring therapeutic avenues

This review explores the intricate relationship between interleukin-6 (IL-6) and sarcopenia, a prevalent condition characterized by progressive skeletal muscle loss, particularly in aging populations. Emphasizing the rising prevalence and health challenges posed by sarcopenia, the paper delves into the multifunctional roles of IL-6 in immune response, inflammation and inflammaging associated with sarcopenia. Significantly elevated in sarcopenic individuals, IL-6 prompts an exploration of its molecular impact on muscle wasting. The review critically assesses IL-6 as a potential biomarker for sarcopenia diagnosis and prognosis while also examining therapeutic interventions targeting IL-6 signaling pathways, offering a foundation for future research and the development of targeted therapeutic strategies to alleviate the impact of this debilitating condition
