The role of chronic low-grade inflammation in the development of sarcopenia: Advances in molecular mechanisms.
With the exacerbation of global population aging, sarcopenia has become an increasingly recognized public health issue. Sarcopenia, characterized by a progressive decline in skeletal muscle mass, strength, and function, significantly impacts the quality of life in the elderly. Herein, we explore the role of chroniclow-gradeinflammation in the development of sarcopenia and its underlying molecular mechanisms, including chronic inflammation-associated signaling pathways, immunosenescence, obesity and lipid infiltration, gut microbiota dysbiosis and intestinal barrier disruption, and the decline of satellite cells. The interplay and interaction of these molecular mechanisms provide new perspectives on the complexity of the pathogenesis of sarcopenia and offer a theoretical foundation for the development of future therapeutic strategies.
期刊介绍：
International Immunopharmacology is the primary vehicle for the publication of original research papers pertinent to the overlapping areas of immunology, pharmacology, cytokine biology, immunotherapy, immunopathology and immunotoxicology. Review articles that encompass these subjects are also welcome.
The subject material appropriate for submission includes:
• Clinical studies employing immunotherapy of any type including the use of: bacterial and chemical agents; thymic hormones, interferon, lymphokines, etc., in transplantation and diseases such as cancer, immunodeficiency, chronic infection and allergic, inflammatory or autoimmune disorders.
• Studies on the mechanisms of action of these agents for specific parameters of immune competence as well as the overall clinical state.
• Pre-clinical animal studies and in vitro studies on mechanisms of action with immunopotentiators, immunomodulators, immunoadjuvants and other pharmacological agents active on cells participating in immune or allergic responses.
• Pharmacological compounds, microbial products and toxicological agents that affect the lymphoid system, and their mechanisms of action.
• Agents that activate genes or modify transcription and translation within the immune response.
• Substances activated, generated, or released through immunologic or related pathways that are pharmacologically active.
• Production, function and regulation of cytokines and their receptors.
• Classical pharmacological studies on the effects of chemokines and bioactive factors released during immunological reactions.
