目的 探索呼吸道合胞病毒( RSV) 感染的氣道上皮細(xì)胞對(duì)大鼠髓系樹突狀細(xì)胞( mDCs) 激活和功能的影響, 為研究RSV 誘發(fā)哮喘的機(jī)制提供依據(jù)。方法 大鼠氣道上皮細(xì)胞株進(jìn)
行培養(yǎng)。在對(duì)RSV 進(jìn)行擴(kuò)增和滴度測(cè)定后, 以不同作用時(shí)間、不同滴度的RSV 感染大鼠氣道上皮細(xì)胞。同時(shí)分離、培養(yǎng)擴(kuò)增大鼠mDCs, 采用transwell 細(xì)胞共培養(yǎng)系統(tǒng)將大鼠氣道上皮細(xì)胞和大鼠mDCs共培養(yǎng)。其mDCs 通過(guò)RT-PCR 和流式細(xì)胞術(shù)檢測(cè)成熟標(biāo)志物和Th2 細(xì)胞因子的表達(dá)、同種異體混合淋巴細(xì)胞反應(yīng)( MLR) 。結(jié)果 大鼠mDCs 與RSV 感染的大鼠氣道上皮細(xì)胞共培養(yǎng)后出現(xiàn)功能性成熟, 包括大鼠mDCs 表面共刺激分子MHCⅡ 和CD86 的表達(dá)增多, OX40L 和TARC 的mRNAs 表達(dá)增高, 大鼠mDCs 刺激T 細(xì)胞增殖的能力增強(qiáng)。結(jié)論 RSV 感染大鼠氣道上皮細(xì)胞能夠促使大鼠mDCs 進(jìn)一步成熟并且可能具有支持Th2 細(xì)胞分化和局部聚集的能力, 可能是RSV 誘發(fā)哮喘的一種機(jī)制。
