Although persistent inflammation has been related to unsuccessful aging, a pro-inflammatory status is the common phenotype in older people. To assess for a genetic component in the inflammatory status of the oldest we studied the distribution of two polymorphic chemokine pathway genes, RANTES and CCR5, in elderly. RANTES -403G/A and RANTES Int1.1T/C polymorphisms and CCR5?32 polymorphism were genotyped in 104 elderly and 110 controls. RANTES -403A and RANTES Int1.1C alleles have been associated with pro-inflammatory and anti-inflammatory status, respectively. CCR5?32 abrogates functional receptor expression of the pro-inflammatory CCR5-mediated action. Prevalence of RANTES -403G allele, associated in other studies with high RANTES production, was reduced in elderly males, compared with con...
