Abstract

Recently, we reported that murine antibody responses to the 23-valent pneumococcal polysaccharide (Pnu-Imune) vaccine declined with age. Here we present data to support the concept that age-associated immune defects are not only due to intrinsic defects in immune cells but are also due to extrinsic factors emanating from the neuroendocrine system. We found that supplementation with dehydroepiandrosterone, a steroid hormone known to be reduced in the aged, corrects the immune deficiency of aged mice and significantly enhanced their splenic immune responses to the Pnu-Imune vaccine.

摘要

最近,我们报道了小鼠对23价肺炎球菌多糖(Pnu-Imune)疫苗的抗体反应随年龄增长而下降。在此,我们提供数据以支持这样一种观点,即与年龄相关的免疫缺陷不仅归因于免疫细胞的内在缺陷,还归因于神经内分泌系统产生的外在因素。我们发现,补充脱氢表雄酮(一种已知在老年时会减少的类固醇激素)可纠正老年小鼠的免疫缺陷,并显著增强它们对Pnu-Imune疫苗的脾脏免疫反应。
