Dipeptidyl peptidase-4 (DPP-4) is known as a highly conserved type II transmembraneous glycoprotein widely distributed in a variety of tissues and cells, and expressed in the peripheral blood as a soluble form. It has been reported that DPP4 play a distinct role in the physiological and pathological processes, such as immune regulation, inflammatory reaction, cell adhesion, and cell apoptosis. DPP4 inhibitor showes an incredible effect on the control of blood glucose and it is thought as a newly-developed drug for diabetes, especially in regulation of post-prandial glycemia. It has been reported that DPP4 plays a potential role in many respiratory diseases, especially in the pathogenesis of asthma.
DPP4是一种高度保守的II型跨膜糖蛋白，广泛分布于组织细胞并可以溶解形式存在于外周血。DPP4参与机体系列生理病理过程，如免疫调节、炎症反应、细胞黏附和细胞调亡等。DPP4抑制剂作为新开发的糖尿病药物在控制血糖尤其是餐后血糖方面效果显著。DPP4及其抑制剂还在多种呼吸系统疾病中具有潜在作用，尤其是在哮喘发病中可能发挥重要作用。.
