結(jié)核病患者中性粒細胞L選擇素的表達及意義
發(fā)布時間:2019-06-11 12:42
【摘要】:目的檢測結(jié)核病患者外周血中性粒細胞(PMN)體外感染結(jié)核分枝桿菌(M.tb)前后L選擇素(CD62L)的表達情況,并探討CD62L在結(jié)核病的發(fā)展過程中的作用。方法應用流式細胞術(shù)檢測結(jié)核病患者PMN表面CD62L的表達,同時檢測正常人PMN的CD62L表達率;體外感染M.tb后,再檢測結(jié)核病患者和正常人PMN的CD62L表達率。結(jié)果結(jié)核病患者PMN表面高表達CD62L,與正常人PMN表面CD62L表達無明顯差異;感染M.tb后,結(jié)核病患者和正常人PMN表面CD62L表達率顯著降低(P0.05)。結(jié)論結(jié)核病患者PMN表面CD62L參與了PMN的趨化過程,在結(jié)核炎癥反應中發(fā)揮重要作用,推動結(jié)核病的發(fā)展過程。
[Abstract]:Objective To detect the expression of L-selectin (CD62L) in the peripheral blood of patients with tuberculosis (PM62L) and to explore the role of CD62L in the development of tuberculosis. Methods The expression of CD62L in PMN was detected by flow cytometry, and the expression rate of CD62L in normal human PMN was detected. Results The expression of CD62L on PMN surface in patients with tuberculosis was not significantly different from that of normal human PMN, and the expression rate of CD62L was significantly lower in patients with tuberculosis and normal controls (P0.05). Conclusion CD62L on PMN surface of patients with tuberculosis is involved in the chemotactic process of PMN, plays an important role in the reaction of tuberculosis, and promotes the development of tuberculosis.
