The immune system declines with aging, leading to an increased susceptibility to infections and higher incidence and progression of autoimmune phenomena and neoplasia. Down syndrome prematurely shows clinical manifestations that are normally seen with aging. This review provides a concise overview of abnormalities in the adaptive immune system of Down syndrome in comparison to normal and precocious (Progeria syndromes) aging. Clinical signs and immunological changes are reviewed. We challenge the hypothesis that the immunological abnormalities in Down syndrome should be interpreted as precocious immunosenescence.
免疫系统随年龄增长而衰退,导致感染易感性增加,自身免疫现象和肿瘤的发生率和进展率更高。唐氏综合征提前表现出通常与衰老相关的临床症状。与正常和早衰(早衰综合征)衰老相比,本综述简要概述了唐氏综合征适应性免疫系统的异常。综述了临床症状和免疫学变化。我们对唐氏综合征的免疫异常应被解释为过早的免疫衰老这一假说提出了质疑。
