摘要:

目的 基于蛋白质组学分析豨莶丸(XXW)治疗类风湿关节炎(RA)的分子机制。 方法 复制大鼠胶原诱导关节炎模型,48只大鼠适应环境后随机分为6组(8只/组),造模成功2周后灌胃豨莶丸进行干预,豨莶丸低、中、高剂量换算后灌胃给药分别为200、400、800 mg/kg,雷公藤多苷片(LGTDGP)9 mg/kg,1次/d。正常对照组和模型对照组灌胃等体积 1% 羧甲基纤维素钠,连续灌胃给药3周。采用ELISA试剂盒测定大鼠血清中IL-10、IL-6、TNF-α 的含量。基于串联质谱标签(TMT)技术筛选豨莶丸高剂量组与模型组间的差异表达蛋白,通过R软件分析核心靶标及信号通路。基于ggplot2、tidyverse 等数据处理与可视化包,对免疫细胞浸润数据及相关基因表达数据进行整合处理,计算核心靶点与各类免疫细胞(如 T 细胞、B 细胞、巨噬细胞等)的相关性。采用免疫组化和免疫荧光验证核心靶点的表达情况。 结果 与正常对照组比较,模型组大鼠血清中TNF-α、IL-6的含量明显升高(P<0.01),IL-10含量降低(P<0.01);与模型组比较,雷公藤多苷片、豨莶丸高剂量、中剂量组大鼠血清中TNF-α、IL-6的含量降低(P<0.01,P<0.05),IL-10含量增加(P<0.05,P<0.01)。蛋白质组学分析发现模型组和豨莶丸高剂量组交集出160个差异蛋白,趋化因子(CCL5),信号转导与转录激活因子1(STAT1),颗粒酶 B (GZMB)和白介素7受体(IL7R)为核心靶点。CCL5、STAT1的ROC曲线下面积大于0.9。4个核心靶点(CCL5,STAT1、GZMB、IL7R)与中央记忆 CD4 T细胞、效应记忆CD4 T细胞、骨髓源性抑制细胞等呈正相关(P<0.05)。免疫组化及免疫荧光分析发现,与空白对照组比较,模型组大鼠踝关节中CCL5、STAT1蛋白表达水平升高(P<0.01);与模型组比较,经豨莶丸治疗后CCL5、STAT1蛋白表达水平降低(P<0.01)。 结论 豨莶丸对CIA大鼠具有关节保护作用,通过降低血清中促炎因子IL-6、TNF-α的含量,同时升高抗炎因子IL-10的水平,减轻炎症反应,其机制与调控CCL5,STAT1等蛋白的表达相关。

Abstract:

Objective To analyze the molecular mechanism of Xixian Pills for treatment of rheumatoid arthritis (RA). Methods Forty-eight rats were randomized into 6 groups (n=8), including a normal control group, a collagen-induced arthritis (CIA) model group, 3 Xixian Pills treatment (200, 400 and 800 mg/kg) groups, and a Tripterygium glycosides tablet (TGT) treatment group. In the latter 4 groups, the rats were treated with daily gavage of Xixian Pills or TGT 2 weeks after CIA modeling for 3 consecutive weeks. The differentially expressed proteins in high-dose Xixian Pills group and the model group compared with the normal control group were screened based on the tandem mass spectrometry tag (TMT) technology, and the core targets and signaling pathways were analyzed. The immune cell infiltration and gene expression data were analyzed using ggplot2 and tidyverse packages, and the correlation coefficients between the core targets and the immune cells were calculated. Results The CIA rats showed significantly increased serum levels of TNF-α and IL-6 and lowered serum IL-10 level. Treatments with high- and medium-dose Xixian Pills and TGT all significantly reduced serum TNF‑α and IL-6 and increased IL-10 levels in CIA rats. Proteomic analysis identified 160 differential proteins between the model group and high-dose Xixian Pills group, and the core targets included CCL5, STAT1, GZMB and IL7R. The areas under the ROC curve of CCL5 and STAT1 were both greater than 0.9. Immunohistochemical and immunofluorescence staining revealed increased levels of CCL5 and STAT1 in the ankle joints of CIA rats, which were significantly decreased after treatment with Xixian Pills. Conclusion Treatment with Xixian Pills offers protection of the joints in CIA rats possibly by inhibiting joint inflammation via regulating protein expressions of CCL5 and STAT1.
