Interactions Between Gut Microbiome and Muscle Tissue in the Development of Sarcopenia
-
Researchers here discuss what is known of the bidirectional relationship between the aging of skeletal muscle and the aging of the gut microbiome. Muscle tissue is metabolically active, generating myokine signals influential on other tissues. This signaling is far from fully mapped, but is known to be important to health, such as via mediating some of the benefits of exercise. Myokine signaling can also affect the composition of the gut microbiome. In turn, changes in the gut microbiome can contribute to the characteristic loss of muscle mass and strength that takes place with advancing age via increased inflammatory signaling or reduced generation of beneficial metabolites known influence muscle metabolism, such as butyrate.
Gut-muscle axis crosstalk in age-related sarcopenia: mechanisms and therapeutic targets (2025)
In this review, we aim to: (1) integrate current knowledge regarding the bidirectional interaction between sarcopenia and gut microbiota; (2) summarize existing management strategies for age-related sarcopenia based on this interaction.
