胃食管反流病(GERD)是胃十二指肠内容物反流进入食管引起的临床表现和病理变化的一组疾病。近年来针对GERD的发病机制的研究发现，在反流物导致黏膜损伤前，免疫炎症反应早已发生并导致上皮细胞发生变化，继而修复机制被激活。其中，酸/非酸反流是诱导免疫和炎症反应的关键因素。因此，开发一种能够有效地阻断由反流引起的炎症级联反应发生的新靶点，将是一种有前途的GERD治疗方法。

Gastroesophageal reflux disease (GERD) is a group of diseases with clinical manifestations and pathological changes caused by gastroduodenal content reflux into esophagus. Recently, some researchers have found that before the mucosal injury, the immune response occurred and caused the epithelial cells to vary in the pathogenesis of GERD. Meantime, the repair mechanism was activated, and acid / non acid reflux was the factor inducing immune and inflammatory response. So, to develop a novel treatment target, which can effectively block the occurrence of inflammatory cascade reaction attributed to reflux, would be a promising treatment of GERD.
