Elderly persons are more susceptible and vulnerable to many infections compared with young adults. This phenomenon can be attributed to a decline in host defense mechanisms, particularly altered immune function. The effects of aging on T- and B-lymphocyte function; antigen-presenting cells, natural killer cells, and granulocytes; and organ-specific host resistance are discussed in this article.
与年轻人相比，老年人更容易受到多种感染且更易患病。这种现象可归因于宿主防御机制的衰退，尤其是免疫功能的改变。本文讨论了衰老对T淋巴细胞和B淋巴细胞功能、抗原呈递细胞、自然杀伤细胞和粒细胞以及器官特异性宿主抵抗力的影响。
