In 10 patients who received a heart lung transplant, TNF-alpha generation by cells collected during bronchioloalveolar lavages (n = 30) and by circulating mononuclear cells was measured. Basal and recombinant IL-2-stimulated productions (50 U/ml) were measured. TNF-alpha concentration was determined by an immunoradiometric assay (IRMA). Circulating mononuclear cells produced at least 4 times less TNF-alpha than BAL cells. Rejection episodes or CMV diseases were not associated with significant changes in TNF-alpha generation. Recombinant IL-2 increased this production in both cell populations but the magnitude of this effect was smaller in BAL cells, suggesting an in vivo preactivation.
在10例接受心肺移植的患者中,对支气管肺泡灌洗(n = 30)收集的细胞以及循环单核细胞产生肿瘤坏死因子-α(TNF-α)的情况进行了测定。测量了基础状态和重组白细胞介素-2(IL-2)刺激(50 U/ml)后的产生情况。TNF-α浓度通过免疫放射分析(IRMA)测定。循环单核细胞产生的TNF-α比支气管肺泡灌洗细胞至少少4倍。排斥反应或巨细胞病毒疾病与TNF-α产生的显著变化无关。重组IL-2增加了这两种细胞群体的TNF-α产生,但这种作用在支气管肺泡灌洗细胞中的幅度较小,提示存在体内预激活。
