title: High innate production capacity of tumor necrosis factor-alpha and decline of handgrip strength in old age.
abstract: Increased signaling of the pro-inflammatory cytokine tumor necrosis factor-alpha (TNF-alpha) elicits apoptosis of skeletal muscle cells in various animal models. Within a population-based prospective follow up study of elderly people aged 85 years we show that a high innate production capacity of TNF-alpha precedes a steeper decline in muscle strength over time.
