Mediators and Patterns of Muscle Loss in Chronic Systemic Inflammation

摘要: Besides its primary function in locomotion, skeletal muscle (SKM), which represents up to half of human’s weight, also plays a fundamental homeostatic role. Through the secretion soluble peptides, or myokines, SKM interacts with major organs involved metabolic processes. In turn, cues from these are received by cells, adapt their response accordingly. This is done through an intricate intracellular signaling network characterized cross-talking between anabolic and catabolic pathways. A fine regulation required protect organism excessive energy expenditure. Systemic inflammation evokes reaction known as sarcopenia. turn this comprises several mechanisms, vary depending on nature insult magnitude. regard, aging, chronic inflammatory systemic diseases, osteoarthritis idiopathic myopathies can lead loss. Interestingly, sarcopenia may persist despite remission inflammation, issue warrants further research. The Janus kinase/signal transducer activator transcription (JAK/STAT) system stands participant loss during while it well-recognized orchestrator cell turnover. Herein we summarize current knowledge about models sarcopenia, triggers mediators effect both protein growth yields. Also, dual action JAK/STAT pathway mass changes discussed. We highlight need unravel precise contribution order design targeted therapeutic strategies.
