Abstract

In this study, we analysed the polymorphic variants of IL-1α (C-T transition at position -889), IL-1β (C-T transition at position -511) and IL-1 receptor antagonist (Ra) (86-bp repeated sequence in intron 2) in 1131 subjects (453 females and 678 males) from Northern and Central Italy, including 134 centenarians, to evaluate whether IL-1 cluster alleles might be differently represented in people selected for longevity. In addition, IL-1Ra and IL-1β plasma levels were quantified by ELISA in 130 randomly selected subjects. No significant differences in the genotype and allele frequency distributions were observed between young, elderly and centenarian subjects. IL-1Ra plasma levels showed an age-related increase, whereas IL-1β plasma levels did not show any detectable age-related trend. Neither IL-1Ra nor IL-1β plasma levels showed any relationship with genotypes of the three IL-1 genes. These results suggest that no one particular polymorphism in the IL-1 gene cluster yields an advantage for survival in the last decades of life, and that the age-related increase in plasma levels of IL-1Ra seems not to be genetically regulated but a likely safeguard mechanism to buffer the age-associated increased inflammatory state.
