摘要:

文题释义:

子宫螺旋动脉重铸:妊娠时,在蜕膜自然杀伤细胞以及绒毛膜外滋养细胞的作用下,子宫螺旋动脉的肌弹性动脉壁被含有绒毛膜外滋养细胞的无定形纤维蛋白物质所取代,子宫螺旋动脉由小直径、低流量、高阻力血管重铸为大直径、高流量、低阻力血管以满足胎儿血液供应。
细胞焦亡:是近年来发现并证实的一种新的炎症性程序性细胞死亡方式,其特征是依赖于炎性半胱天冬酶(主要是caspase-1,4,5,11),细胞不断胀大直至细胞膜破裂,导致细胞内容物的释放进而激活强烈的炎症反应。


背景:子宫螺旋动脉重铸的顺利进行是正常妊娠的必要条件之一,血管平滑肌细胞是此过程的重要细胞。干扰素γ与妊娠早期螺旋动脉血管平滑肌细胞丢失相关,但具体机制尚未明确。
目的:探讨干扰素γ通过NLRP3/caspase-1/GSDMD焦亡途径对血管平滑肌细胞迁移、凋亡生物学功能的影响。
方法:人血管平滑肌细胞分为对照组和干扰素γ组,对照组正常培养,干扰素γ组采用10 ng/mL干扰素γ处理24 h。Transwell实验检测血管平滑肌细胞的迁移能力;荧光TUNEL实验及流式细胞术检测血管平滑肌细胞的凋亡情况;qPCR检测NLRP3和caspase-1 mRNA表达水平;Western blot检测NLRP3、caspase-1、cleaved N-terminal GSDMD蛋白表达水平。
结果与结论:与对照组相比,干扰素γ组血管平滑肌细胞的迁移能力及凋亡率显著升高(P < 0.05);与对照组相比,干扰素γ组血管平滑肌细胞中NLRP3和caspase-1 mRNA表达水平显著升高(P < 0.05);与对照组相比,干扰素γ组血管平滑肌细胞中NLRP3、caspase-1、cleaved N-terminal GSDMD蛋白表达水平显著升高(P < 0.05)。结果表明,干扰素γ可能通过NLRP3/caspase-1/GSDMD焦亡途径调控血管平滑肌细胞的迁移和凋亡。

Abstract: BACKGROUND: Successful uterine spiral artery remodeling is necessary for normal pregnancy, in which vascular smooth muscle cells are important cells. Interferon-γ is associated with the loss of vascular smooth muscle cells during early pregnancy. However, the specific mechanism is not fully understood.  
OBJECTIVE: To investigate the effects of interferon-γ on migration and apoptosis of vascular smooth muscle cells through NLRP3/caspase-1/GSDMD pyroptosis pathway.
METHODS: Human vascular smooth muscle cells were divided into control group and interferon-γ group. The control group was cultured normally, and the interferon-γ group was treated with 10 ng/mL interferon-γ for 24 hours. The migration ability of vascular smooth muscle cells was detected by Transwell assay. The apoptosis of vascular smooth muscle cells was detected by TUNEL assay and flow cytometry. The mRNA expression levels of NLRP3 and caspase-1 were detected by qPCR. Western blot assay was utilized to detect NLRP3, caspase-1, and cleaved N-terminal GSDMD protein expression levels.
RESULTS AND CONCLUSION: Compared with the control group, the migration ability and apoptosis rate of vascular smooth muscle cells in interferon-γ group were significantly increased (P < 0.05). Compared with the control group, the mRNA expression levels of NLRP3 and caspase-1 in vascular smooth muscle cells of interferon-γ group were significantly increased (P < 0.05). Compared with control group, the expression levels of NLRP3, caspase-1, and cleaved N-terminal GSDMD protein in vascular smooth muscle cells in the interferon-γ group were significantly increased (P < 0.05). The results suggest that interferon-γ may regulate the migration and apoptosis of vascular smooth muscle cells through NLRP3/caspase-1/GSDMD pyroptosis pathway.
