摘要/Abstract

摘要： 目的探讨人外周血中炎症因子的表达与炎性衰老的相关性。方法通过招募年轻和老年志愿者,检测外周血中炎症因子IL-6、IL-8、TNF-α和IL-1β的mRNA表达水平和蛋白水平。结果显示老年个体组中IL-6,IL-8和TNF-α的mRNA表达水平高于年轻组,且蛋白水平呈现相同的趋势,比较差异均有统计学意义（P<0.05）。此外,通过热图分析了炎症因子mRNA和蛋白水平的相对表达谱,也发现相同的结果。结论当年龄超过65岁以后,随着年龄的增长,体内的炎症因子表达水平会升高,这一结果具有成为炎性衰老生物标志物的潜力,对评估老年人的健康状况和疾病风险具有重要意义。

Abstract: Objective To explore the correlation between the expression of inflammatory factors in human peripheral blood and inflamm-aging．Methods In this experiment,the young and old volunteers were recruited to detect mRNA and protein levels of IL-6,IL-8,TNF-α and IL-1β in peripheral blood．Results The results indicated that mRNA expression levels of IL-6,TNF-α and IL-8 in the old individuals were higher than the young individuals,and the protein concentration followed the same trend,with acceptable P value suggesting a great statistically significant difference．In addition,the relative expression profiles of mRNA and protein concentrations of inflammatory cytokines were analyzed by heat map,and the same results were found．Conclusions It shows that the expression level of inflammatory cytokines up-regulates along with age goes on over 65,which has the potential of inflammatory biomarkers of aging．
