Liraglutide is a highly potent, long-acting GLP-1 receptor agonist (EC50 = 61 pM)and shares 97% of its amino acid sequence identity with human GLP-1 [6,7].
The number of viable cells in hepatocytes treated with PA/LPS was significantly reduced, and liraglutide reversed the decline in cell viability in a concentration-dependent manner. Liraglutide at 100 nM significantly increased cell viability compared with higher concentrations[1].In H9c2 cardiomyoblasts,Pretreatment with 100 nM liraglutide could efficiently inhibit TNF-α and hypoxia-induced inflammasome activation. liraglutide reversed the level of SIRT1,Liraglutide diminished the levels of ROS generation and NOX4 expression[2]. Liraglutide relieved steatosis by improving hepatic fat synthesis, transportation, storage, and use via PI3K and AMPK pathways [3].The cytoplasmic lipid droplet accumulation was visibly decreased in foam cells by treatment with liraglutide. The TG and cholesterol content in the liraglutide-treated foam cells was significantly decreased. Expression level of AMPKα1 and phosphorylated AMPKα1 was significantly increased while the expression level of SREBP1 and phosphorylated SREBP1 was significantly decreased in foam cells following treatment with liraglutide[5].
In mice,The combination of HFD, Acrp30 knockdown and ApoE deficiency had additive effects on the development of insulin resistance (IR) and NAFLD. Administration of liraglutide prevented the development of HFD and hypoadiponectinaemia-induced IR and NAFLD in this model. Liraglutide also attenuated the expression of proinflammatory cytokines or transcription factor, including TNF-α and NF-κB(65) , and the expression of two lipogenesis-related genes, Acetyl-CoA Carboxylase (ACC) and fatty acid synthase (FAS)[4].

用 PA/LPS 处理的肝细胞中的活细胞数量显着减少,利拉鲁肽以浓度依赖性方式逆转细胞活力的下降。与更高浓度相比,100 nM 利拉鲁肽可显着提高细胞活力[1]。在 H9c2 心肌细胞中,100 nM 利拉鲁肽预处理可有效抑制 TNF-α 和缺氧诱导的炎性体激活。 liraglutide 逆转 SIRT1 水平,Liraglutide 降低 ROS 生成和 NOX4 表达水平[2]。利拉鲁肽通过 PI3K 和 AMPK 通路改善肝脏脂肪的合成、运输、储存和使用,从而减轻脂肪变性[3]。利拉鲁肽处理后,泡沫细胞中的细胞质脂滴积累明显减少。利拉鲁肽处理的泡沫细胞中的甘油三酯和胆固醇含量显着降低。利拉鲁肽处理后泡沫细胞中AMPKα1和磷酸化AMPKα1的表达水平显着升高,而SREBP1和磷酸化SREBP1的表达水平显着降低[5]。
在小鼠中,HFD、Acrp30 敲低和 ApoE 缺陷的组合对胰岛素抵抗 (IR) 和 NAFLD 的发展具有累加效应。在该模型中,利拉鲁肽的给药阻止了 HFD 和低脂联素血症诱导的 IR 和 NAFLD 的发展。利拉鲁肽还减弱促炎细胞因子或转录因子的表达,包括 TNF-α 和 NF-κB(65),以及两种脂肪生成相关基因乙酰辅酶 A 羧化酶 (ACC) 和脂肪酸合酶 (FAS) 的表达[4].
