title: Probiotics-induced increase of large intestinal luminal polyamine concentration may promote longevity.
abstract: Many mechanisms contribute to senescence, such as telomere shortening in replicative cells, cumulative damage to DNA leading to genomic instability, and oxidative damage to molecules by reactive oxygen species (ROS). These include chronic low-grade inflammation (inflammageing), a major risk factor for ageing and age-related diseases, such as Alzheimer's disease and type II diabetes. Furthermore, the prevention of inflammageing seems to be one of the most effective approaches to increase longevity. Here, I discuss the rationale and recent evidence for probiotic-induced upregulation of intestinal luminal polyamine (PA) production in the extension of lifespan by preventing inflammageing.
