Abstract
Population ageing is increasing in prevalence in most developed countries. Ageing is the decline of functional properties at the cellular, tissue, and organ level. Biochemical changes that occur in all organisms that experience biological ageing are referred to as the "Hallmarks of ageing". Inflammation is a common denominator of the hallmarks of ageing, being mechanistically involved in most age-related health consequences. Inflamm-ageing refers to age-related changes in the inflammatory and immune systems which somehow drive the ageing process towards healthy or unhealthy ageing. Current evidences, support that, reversing the age-related pro-inflammatory status of inflamm-ageing, is able to modulate most hallmarks of ageing. Inflamm-ageing is associated with increased levels of pro-inflammatory molecules (e.g. cytokines, chemokines), ultimately producing a chronic low-grade inflammatory state typically observed in older individuals. It is commonly accepted that, the balance between pro- and anti-inflammatory cytokines/chemokines is one of the factors determining whether healthy or unhealthy ageing occurs. Malnutrition and nutritional imbalances, are highly prevalent in the elderly, playing a role in driving the balance of pro- and anti-inflammatory immunoactive molecules. In particular, malnutrition is a major risk factor for sarcopenia, a phenomenon characterized by loss of muscle mass, which is often referred to as the biological basis for frailty. Given the close relationship between malnutrition and sarcopenia, there is also evidence for a link between malnutrition and frailty. Indeed, changes in cytokine/chemokine levels in elderly patients with malnutrition were demonstrated. The demonstration that specific cytokines play a role in modulating appetite and nutrient sensing and taste reception, provided further evidence for the existence of a link between inflamm-ageing, nutrition and cytokines in shaping the trajectory of ageing. The present review will overview current evidence supporting the role of specific circulating cytokines and chemokines in the relationship between ageing, inflammation, and malnutrition.
期刊介绍:
Cytokine & Growth Factor Reviews is a leading publication that focuses on the dynamic fields of growth factor and cytokine research. Our journal offers a platform for authors to disseminate thought-provoking articles such as critical reviews, state-of-the-art reviews, letters to the editor, and meeting reviews.
We aim to cover important breakthroughs in these rapidly evolving areas, providing valuable insights into the multidisciplinary significance of cytokines and growth factors. Our journal spans various domains including signal transduction, cell growth and differentiation, embryonic development, immunology, tumorigenesis, and clinical medicine.
By publishing cutting-edge research and analysis, we aim to influence the way researchers and experts perceive and understand growth factors and cytokines. We encourage novel expressions of ideas and innovative approaches to organizing content, fostering a stimulating environment for knowledge exchange and scientific advancement.
