目的 檢測(cè)單一免疫球蛋白白細(xì)胞介素1 受體相關(guān)蛋白( SIGIRR) 在正常肺組織及脂多糖( LPS ) 誘導(dǎo)的肺泡上皮細(xì)胞急性損傷中的表達(dá)。方法 收集手術(shù)切除的正常肺組織標(biāo)本20 例,分別采用免疫組織化學(xué)、Western blot、RT-PCR 法檢測(cè)SIGIRR 的表達(dá)。以終濃度10 μg/mL的LPS 刺激人Ⅱ型肺泡上皮細(xì)胞來(lái)源的A549 細(xì)胞, 于刺激前, 刺激后3、6、12 及24 h 分別以Western blot 法檢測(cè)SIGIRR 表達(dá)的變化。將含有SIGIRR cDNA 全長(zhǎng)的表達(dá)載體瞬時(shí)轉(zhuǎn)染A549 細(xì)胞, 使SIGIRR 在A549 細(xì)胞過(guò)表達(dá)。通過(guò)MTT 法檢測(cè)LPS 對(duì)A549 細(xì)胞的損傷作用。結(jié)果 不同檢測(cè)方法發(fā)現(xiàn)SIGIRR 在正常肺組織中均有表達(dá); 免疫組織化學(xué)檢測(cè)可見(jiàn)SIGIRR 表達(dá)于肺泡上皮細(xì)胞。LPS 刺激后3、6 及12 h 時(shí)SIGIRR 表達(dá)較刺激前均下調(diào), 24 h后回升至刺激前水平。MTT 試驗(yàn)表明過(guò)表達(dá)SIGIRR 的A549 細(xì)胞在接受LPS 刺激后生長(zhǎng)抑制率顯著低于對(duì)照組。結(jié)論 SIGIRR 能夠表達(dá)于正常肺組織, 且能夠減輕LPS 刺激導(dǎo)致的肺泡上皮細(xì)胞損傷。提示SIGIRR 可能參與了LPS 誘導(dǎo)的ALI的調(diào)節(jié)。
