The effect of aging on the ability of macrophages to produce endogenous pyrogen/interleukin-1 (EP/IL-1) was tested in 13 young adult (2-3 mo) and 13 aged (24-26 mo) Fischer rats using a febrile response assay. Peritoneal macrophages from aged rats produced EP/IL-1 as well as young adult rats. Decreased production of EP/Il-1 does not appear to explain the diminished febrile response seen in the elderly.
利用发热反应测定法,在13只年轻成年(2 - 3个月)和13只老年(24 - 26个月)的费希尔大鼠中,测试了衰老对巨噬细胞产生内源性致热原/白细胞介素-1(EP/IL-1)能力的影响。老年大鼠的腹腔巨噬细胞产生EP/IL-1的情况与年轻成年大鼠一样。EP/Il-1产生量的减少似乎并不能解释老年人发热反应减弱的现象。
