subsp. () is the etiological agent of contagious bovine pleuropneumonia (CBPP), one of the major diseases affecting cattle in sub-Saharan Africa. Some evidences suggest that the immune system of the host (cattle) plays an important role in the pathogenic mechanism of CBPP, but the factors involved in the process remain largely unknown. The present study aimed to investigate the cell response of bovine polymorphonuclear neutrophils (PMNs) after exposure using one step RT-qPCR and Western blotting. Data obtained indicate that gene and protein expression levels of some pro-inflammatory factors already change upon 30 min of PMNs exposure to . Of note, mRNA expression level in exposed PMNs increased in a time-dependent manner and for all time points investigated; targets expression was also detected by Western blotting in exposed PMNs only. These data demonstrate that when bovine PMN cells are triggered by , they undergo molecular changes, upregulating mRNA and protein expression of specific pro-inflammatory factors. These results provide additional information on host-pathogen interaction during CBPP infection.
亚种()是牛传染性胸膜肺炎(CBPP)的病原体,CBPP是撒哈拉以南非洲影响牛群的主要疾病之一。一些证据表明,宿主(牛)的免疫系统在CBPP的致病机制中起重要作用,但该过程涉及的因素仍大多未知。本研究旨在使用一步法RT-qPCR和蛋白质免疫印迹法研究牛多形核中性粒细胞(PMN)暴露后的细胞反应。获得的数据表明,PMN暴露于后30分钟,一些促炎因子的基因和蛋白质表达水平就已发生变化。值得注意的是,暴露的PMN中的mRNA表达水平在所有研究的时间点均呈时间依赖性增加;仅在暴露的PMN中通过蛋白质免疫印迹法也检测到了靶标表达。这些数据表明,当牛PMN细胞被触发时,它们会发生分子变化,上调特定促炎因子的mRNA和蛋白质表达。这些结果为CBPP感染期间的宿主-病原体相互作用提供了更多信息。
