目的 探索呼吸道合胞病毒( RSV) 感染的氣道上皮細胞對大鼠髓系樹突狀細胞( mDCs) 激活和功能的影響, 為研究RSV 誘發(fā)哮喘的機制提供依據(jù)。方法 大鼠氣道上皮細胞株進
行培養(yǎng)。在對RSV 進行擴增和滴度測定后, 以不同作用時間、不同滴度的RSV 感染大鼠氣道上皮細胞。同時分離、培養(yǎng)擴增大鼠mDCs, 采用transwell 細胞共培養(yǎng)系統(tǒng)將大鼠氣道上皮細胞和大鼠mDCs共培養(yǎng)。其mDCs 通過RT-PCR 和流式細胞術檢測成熟標志物和Th2 細胞因子的表達、同種異體混合淋巴細胞反應( MLR) 。結果 大鼠mDCs 與RSV 感染的大鼠氣道上皮細胞共培養(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 的表達增多, OX40L 和TARC 的mRNAs 表達增高, 大鼠mDCs 刺激T 細胞增殖的能力增強。結論 RSV 感染大鼠氣道上皮細胞能夠促使大鼠mDCs 進一步成熟并且可能具有支持Th2 細胞分化和局部聚集的能力, 可能是RSV 誘發(fā)哮喘的一種機制。
