Urine of some febrile patients exhibits a TNF-alpha inhibitory activity (TNF-alpha INH), sensitive to heat and trypsin, with an apparent mol wt of 40-60 X 10(3) and a pI range of 5.5-6.1. As for the Il-1 INH, the TNF INH activity involves a competitive mechanism of action suggesting the existence of a family of negative feedback-regulating molecules interfering with cytokines actions.
一些发热患者的尿液表现出对热和胰蛋白酶敏感的肿瘤坏死因子-α抑制活性(TNF-α INH),其表观分子量为40 - 60×10³,等电点范围为5.5 - 6.1。至于白细胞介素-1抑制物(Il-1 INH),TNF抑制活性涉及一种竞争性作用机制,提示存在一族干扰细胞因子作用的负反馈调节分子。
