Abstract

Earlier we reported that about 60% of patients suffering from unexplained relapsing of chronic purulent rhinosinusitis show a defective T cell-mediated immunity to commensal microorganisms of the upper respiratory tract. The monocyte chemotactic responsiveness was assessed in 40 of these patients by means of the polarization assay. Impaired FMLP-induced monocyte polarization was found in 26 of the 40 patients tested. The defective chemotactic responsiveness could be explained by a p15E-related factor detectable in the serum of the patients: addition of serum fractions less than 25 kD to healthy donor monocytes resulted in an inhibition of polarization; a monoclonal antibody directed against p15E neutralized this inhibitory effect. In individual patients, a decreased monocyte polarization correlated well with the presence of this p15E-related factor in serum, as well as with defective T cell reactivity.

摘要

我们之前报道过,约60%患有慢性化脓性鼻窦炎不明原因复发的患者,对呼吸道共生微生物表现出T细胞介导的免疫缺陷。通过趋化分析对其中40例患者的单核细胞趋化反应性进行了评估。在40例接受检测的患者中,有26例发现甲酰甲硫氨酸-亮氨酸-苯丙氨酸(FMLP)诱导的单核细胞趋化受损。趋化反应性缺陷可以用患者血清中可检测到的一种与p15E相关的因子来解释:将小于25kD的血清组分添加到健康供体单核细胞中会导致趋化抑制;针对p15E的单克隆抗体可中和这种抑制作用。在个体患者中,单核细胞趋化降低与血清中这种与p15E相关的因子的存在以及T细胞反应性缺陷密切相关。
