We basically investigated the role of macrophage migration inhibitory factor(MIF) in esophageal diseases. The expression of MIF protein in the esophagus of rats was less than that of stomach and intestine in rat. We developed MIF DNA vaccine, which is a novel MIF inhibitor, and this vaccine ameliorated the severity of intestinal inflammation in mice. In the study using MIF knockout mice, MIF did not affect the level of gastric acid-secretion in mice. MIF knockout mice were resistant to drug-induced gastrointestinal inflammation, partly via induction of heat shock protein. Treatment with MIF inhibitor suppressed eosinophil infiltrate in the esophagus of mice.

我们主要研究巨噬细胞迁移抑制因子（MIF）在食管疾病中的作用。 MIF蛋白在大鼠食管中的表达量低于大鼠胃和肠中的表达量。我们开发了 MIF DNA 疫苗，这是一种新型 MIF 抑制剂，这种疫苗可以改善小鼠肠道炎症的严重程度。在使用 MIF 基因敲除小鼠的研究中，MIF 并不影响小鼠的胃酸分泌水平。 MIF 基因敲除小鼠对药物引起的胃肠道炎症具有抵抗力，部分是通过诱导热休克蛋白实现的。用 MIF 抑制剂治疗可抑制小鼠食道中的嗜酸性粒细胞浸润。
