二肽基肽酶4的多功能性及相关药物靶点作用机制的研究进展

Progress in study of multifunctionality of DPP4 andmechanism of action of related drug targets

二肽基肽酶4(dipeptidyl peptidase 4,DPP4)是丝氨酸膜固定的外肽酶,在人体的多项生理或病理活动过程中发挥重要调控作用。DPP4不仅作为转录因子调控下游靶基因的转录和表达,还能作为不依赖于转录的调节因子,通过蛋白间的相互作用,发挥其调控作用。在目前研究中,DPP4与多种疾病密切相关,并且已发现多种具有潜在靶向DPP4的物质。该文主要综述了DPP4在调节机体能量代谢、炎症、组织修复和癌变等多个方面的多功能性。同时,以慢性肝病的病理发展过程为基础,还综述了DPP4体外抑制剂的筛选以及其在调控慢性肝病方面的研究进展。

DPP4 is a serine exopeptidase that is immobilized on the cell membrane and plays a crucial regulatory role in various physiological and pathological activities within the human body.In addition to acting as a transcription factor to regulate the transcription and expression of downstream target genes,DPP4 also functions as a transcription-independent regulator through protein-protein interactions.In recent studies,DPP4 has been strongly linked to various diseases,and several substances with the potential to target DPP4 have been identified.This paper mainly reviews the multifunctionality of DPP4 in regulating various aspects of energy metabolism,inflammation,tissue repair and carcinogenesis in the body.It also reviews the screening of in vitro inhibitors of DPP4 and its research progress in regulating chronic liver disease,based on the pathological development process of chronic liver disease.
