研究目的:

本研究拟通过人体、动物和细胞三个方面出发,运用单克隆抗体、流式细胞仪、分子生物学、蛋白质谱分析等技术,首先,探索GLP-1RA药物是否对T2DM人体外周循环内皮祖细胞的数量及动员有增加,这一作用是否有助于解释GLP-1RA药物对于心血管的受益;其次探索GLP-1RA药物是否改善了T2DM机体炎症反应及氧化应激水平,是否通过调控内皮祖细胞GLP-1/cAMP/VEGF、SDF-1/CRCX4、eNOS/NO/MMP-9通路改善糖尿病大血管病变及下肢缺血病变;细胞方面,通过细胞培养、蛋白质谱分析和内皮细胞成管实验,进一步探索GLP-1RA药物促进新生血管形成的机制。  

Objectives of Study:

This study aims to explore whether GLP-1RA drugs increase the number and mobilization of endothelial progenitor cells in the peripheral circulation of T2DM individuals using techniques such as monoclonal antibodies, flow cytometry, molecular biology, and protein mass spectrometry from three aspects: human body, animal, and cell. Does this effect help explain the cardiovascular benefits of GLP-1RA drugs; Secondly, to explore whether GLP-1RA drugs can improve the level of inflammation and oxidative stress in T2DM, and whether they can improve the macroangiopathy and lower limb ischemic lesions in diabetes by regulating the GLP-1/cAMP/VEGF, SDF-1/CRCX4, eNOS/NO/MMP-9 pathways of endothelial progenitor cells; In terms of cells, the mechanism of GLP-1RA drug promoting neovascularization is further explored through cell culture, protein mass spectrometry analysis, and endothelial cell vasculogenesis experiments.
