The aim of this work was to determine the presence of galectin-10 in nasal lavage fluid (NLF) of patients with aspirin-sensitive respiratory disease (ASRD) before and after challenge with L-ASA (aspirin) by ELISA. Fifteen ASRD patients, ten aspirin-tolerant asthmatics (ATA), and fifteen healthy controls (HC) were studied. The baseline presence of Galectin-10 in PBMC was determined using real time PCR. Galectin-10 was evaluated in tissue of nasal polyps by western blot. Our results showed a lower expression in PBMC of ASRD patients than in ATA and healthy controls. However, a higher concentration of galectin-10 in NLF was found in ASRD patients before and after L-ASA challenge; western blot confirmed a high expression of galectin-10 in tissue from nasal polyps obtained from ASRD patients. Our results suggest a probable role of galectin-10 in the inflammatory response observed in ASRD patients; however, confirmatory studies are needed.
这项工作的目的是通过酶联免疫吸附测定(ELISA)来确定阿司匹林敏感呼吸道疾病(ASRD)患者在L-ASA(阿司匹林)激发前后鼻灌洗液(NLF)中半乳糖凝集素-10的存在情况。研究了15例ASRD患者、10例阿司匹林耐受哮喘患者(ATA)和15例健康对照者(HC)。使用实时聚合酶链反应(PCR)测定外周血单核细胞(PBMC)中半乳糖凝集素-10的基线存在情况。通过蛋白质免疫印迹法(western blot)评估鼻息肉组织中的半乳糖凝集素-10。我们的结果显示,ASRD患者PBMC中的表达低于ATA患者和健康对照者。然而,在L-ASA激发前后,ASRD患者的NLF中半乳糖凝集素-10浓度较高;蛋白质免疫印迹法证实,从ASRD患者获得的鼻息肉组织中半乳糖凝集素-10表达较高。我们的结果表明,半乳糖凝集素-10在ASRD患者观察到的炎症反应中可能起作用;然而,还需要进行验证性研究。
