目的 探讨Rho相关GTP结合蛋白F（RhoF）介导的Th17极化在重度急性胰腺炎（SAP）发生中的作用及机制研究。 方法 将RhoF转基因小鼠随机分为3组：对照组（n = 10）、SAP组（n = 10）和SAP+Y-27632组（n = 10）。另将WT小鼠随机分为3组：对照组（n = 10）、SAP组（n = 10）和SAP+Y-27632组（n = 10）。除对照组外，其他组建立SAP模型。SAP+Y-27632组在模型建立后，通过尾静脉输注Y-27632。分离小鼠血液样本中的T细胞，用于RhoF、p-MYPT1蛋白检测和ROCK活性测定，并采用流式细胞仪分析产生IL-17的淋巴CD4+T细胞的百分比。 结果 与对照组相比，SAP组小鼠T细胞中RhoF、p-MYPT1表达量增加（P < 0.01），并且RhoF的水平与p-MYPT1的水平密切相关（P < 0.05）。与WT组相比，RhoF组小鼠T细胞的RhoF蛋白水平的表达增加约30%，并且CD4+ T细胞自发产生IL-17的水平显著增加（P < 0.01）。与WT小鼠相比，RhoF转基因小鼠胰腺损伤的组织学评分，T细胞的RhoF、p-MYPT1表达量，IL-17+ T细胞数量和血清IL-17水平明显增加（P < 0.05）。SAP+Y-27632组的组织学评分，T细胞的RhoF、p-MYPT1表达量，IL-17+ T细胞数量和血清IL-17水平显著低于SAP组（P < 0.05）。 结论 RhoF/ROCK信号通路介导的Th17细胞极化参与SAP的发病机制。

Objective To investigate the role and mechanism of Rho-related GTP-binding protein F （RhoF）-mediated Th17 polarization in the development of severe acute pancreatitis （SAP）. Methods RhoF transgenic mice were randomly divided into control group （n = 10）， SAP group （n = 10） and SAP+Y-27632 group （n = 10）， and WT mice were randomly divided into control group （n = 10）， SAP group （n = 10） and SAP+Y-27632 group （n = 10）. SAP models were established in all groups except the control group. The SAP+Y-27632 group was infused with Y-27632 via tail vein after model establishment. T cells in mouse blood samples were isolated for RhoF， p-MYPT1 protein detection and ROCK activity determination， and the percentage of lymphoid CD4+T cells producing IL-17 was analyzed by flow cytometry. Results The expression of RhoF and p-MYPT1 was increased in T cells in the SAP group compared with that in the control group （P < 0.01）， and the level of RhoF was closely correlated with that of p-MYPT1 （P = 0.018）. The expression of RhoF protein level in T cells of mice in the RhoF group increased by approximately 30% compared to that in the WT group， and the level of spontaneous IL-17 production by CD4+ T cells was significantly increased （P = 0.003）. Compared with WT mice， the histological score of pancreatic injury， the expression of RhoF and p-MYPT1 in T cells， the number of IL-17+ T cells and serum IL-17 level in RhoF transgenic mice were significantly increased （P < 0.05）. The histological score， RhoF and p-MYPT1 expression of T cells， IL-17+ T cell numbers and serum IL-17 level were significantly lower in the SAP+Y-27632 group than those in the SAP group （P < 0.05）. Conclusion RhoF/ROCK signaling pathway-mediated polarization of Th17 cells is involved in the pathogenesis of SAP.
