摘要

Skeletal muscle mass is gradually lost during ageing, a process referred to as sarcopenia (Greenlund and Nair, 2003). Ageing is associated with chronic inflammation, whose intensity is very variable within old individuals (Ferracci et al., 2002; Mayotet al., 2007). The age-associated low-grade inflammation has been suggested to contribute to sarcopenia (Roubenoff, 2003). We have recently shown that sarcopenia is not enhanced in low-grade inflamed old rats compared to age-matched non-inflamed rats, when they are maintained in their breeding conditions (Mayot et al., 2006). However, low-grade inflammation could be a factor associated with an increased risk of muscle mass loss in case of any additional stress in old individuals.
