胸膜结核(TB)和淋巴结核一起占所有肺外病例的一半以上。TB中的胸腔积液(PE)是以T细胞为主的淋巴细胞性PE的代表。然而,T淋巴细胞在PE中归巢和积聚的机制仍不完全清楚。在这里,我们通过蛋白质阵列分析对来自TB患者和非TB患者的PE中的细胞因子丰度进行了比较分析,并观察到与外周血相比,MCP-2/CCL 8在TB-PE中高度表达。同时,我们观察到MCP-2/CCL 8的主要受体CCR 5主要表达于胸膜CD 4 + T淋巴细胞上。此外,我们发现,无论是牛分枝杆菌卡介苗(BCG)或结核分枝杆菌H37 Rv感染诱导MCP-2/CCL 8在Raw 264. 7和THP-1巨噬细胞,小鼠腹腔巨噬细胞以及人PBMC单核细胞衍生的巨噬细胞(MDM)在转录和蛋白质水平的生产。分枝杆菌诱导MCP-2/CCL 8的表达依赖于TLR 2/PI 3 K/Akt和p38信号通路的激活。我们的结论是MCP-2/CCL 8在TB-PE中的积累可以作为TB诊断的生物标志物。
Pleural tuberculosis (TB), together with lymphatic TB, constitutes more than half of all extrapulmonary cases. Pleural effusions (PEs) in TB are representative of lymphocytic PEs which are dominated by T cells. However, the mechanism underlying T lymphocytes homing and accumulation in PEs is still incompletely understood. Here we performed a comparative analysis of cytokine abundance in PEs from TB patients and non-TB patients by protein array analysis and observed that MCP-2/CCL8 is highly expressed in the TB-PEs as compared to peripheral blood. Meanwhile, we observed that CCR5, the primary receptor used by MCP-2/CCL8, is mostly expressed on pleural CD4+ T lymphocytes. Furthermore, we found that infection with either Mycobacterium bovis Bacillus Calmette-Guérin (BCG) or Mycobacterium tuberculosis H37Rv induced production of MCP-2/CCL8 at both transcriptional and protein level in Raw264.7 and THP-1 macrophage cells, mouse peritoneal macrophages as well as human PBMC monocyte-derived macrophages (MDMs). The induction of MCP-2/CCL8 by mycobacteria is dependent on the activation of TLR2/PI3K/Akt and p38 signaling pathway. We conclude that accumulation of MCP-2/CCL8 in TB-PEs may function as a biomarker for TB diagnosis.
