Aging of the human body affects the immune system by a decline in the ability to raise a response to challenges such as microbial infections or vaccinations. In the very elderly, the decline in such functions appears to relate to a reduced expression of certain co-stimulatory molecules expressed by T lymphocytes. More recently, attention has been drawn to the adhesion molecule CD62L, where differences in expression and function of this molecule between younger and older individuals are suspected to be a part of immunosenescence in the elderly.
人体衰老会影响免疫系统,其应对微生物感染或疫苗接种等挑战的反应能力会下降。在高龄老人中,此类功能的下降似乎与T淋巴细胞表达的某些共刺激分子的表达减少有关。最近,黏附分子CD62L受到关注,年轻个体与老年个体之间该分子在表达和功能上的差异被怀疑是老年人免疫衰老的一部分。
