摘要:
目的 探讨白细胞介素-1β(IL-1β)对精氨酸升压素(AVP)诱导下心脏成纤维细胞(CF)胶原凝胶收缩的作用。方法 以胰蛋白酶消化法分离、培养SD大鼠的CF,建立成纤维细胞与胶原构成的三维培养体系,测定基础状态下不同浓度的IL-1β作用下,CF胶原凝胶收缩指数,以及IL-1β对AVP作用后CF胶原凝胶收缩指数的影响。实验共分为8个组,即不同浓度(0、50、100、200及400 kU/L)的IL-1β组、不同浓度(0、1×10-7 mol/L)的AVP干预组及100 kU/L IL-1β+1×10-7 mol/L AVP组,每组各设8个孔(n=8)。结果 在基础状态下,以50~400 kU/L IL-1β作用后,CF胶原凝胶收缩指数随着IL-1β干预浓度的增加呈下降趋势,各实验组胶原凝胶收缩指数均明显低于对照组(P<0.01),各实验组之间两两比较的差异也非常显著(P<0.01)。1×10-7 mol/L AVP组CF胶原凝胶收缩指数明显高于0 mol/L AVP组(P<0.01);而100 kU/L IL-1β组CF胶原凝胶收缩指数明显低于0 kU/L IL-1组(P<0.01)。IL-1β与AVP共同作用后,CF胶原凝胶收缩指数介于AVP组和IL-1β组之间,并且与二者之间的差异均有非常显著的意义(P<0.01)。结论 IL-1β可抑制基础状态下CF胶原凝胶收缩,并对AVP促CF胶原凝胶收缩具有明显的拮抗作用。
Abstract:
AIM To explore the effects of interleukin(IL)-1β on collagen gel contraction induced by argipressin (AVP) in cardiac fibroblasts (CF). METHODS Using trypsin separate and culture cardiac fibroblasts (CF) of SD neonatal rats, we set up a three-dimensional culture system of CF and collagen gel. RESULTS With the pretreatment with IL-1β (50~400 kU/L) in CF, the collagen gel contraction index decreased with the increasing concentration of IL-1β, and the index in each test group was significantly lower than that in control (P<0.01). The collagen gel contraction index of pretreatment with AVP was significantly higher than that in control (P<0.01) whereas the index of pretreatment with IL-1β was significantly lower than that in control (P<0.01). Following simultaneous pretreatment with AVP and IL-1β, the index was between those of the two groups, with significant difference between AVP or IL-1β (P<0.01). CONCLUSION IL-1β inhibits collagen gel contraction in basic condition and antagonizes the effects of AVP on collagen gel contraction.
