Changes in the pattern of cytokines found in CD4 and CD8 T cells during the growth of Mycobacterium tuberculosis that resulted in the establishment of a latent infection were monitored. Subsets of T cells were identified based on their differential expression of CD45 and CD44 which allowed them to be classified as naive, activated or memory. We found that the T cells in the lung produced a predominantly type 1 cytokine response. The appearance of large numbers of Th1 cells coincided with the establishment of latency. In contrast, the predominant response in the mediastinal lymph node and spleen was a Th2-type response.
监测了结核分枝杆菌生长过程中CD4和CD8 T细胞中细胞因子模式的变化,这些变化导致了潜伏感染的建立。根据T细胞表面CD45和CD44的差异表达来识别其亚群,从而将它们分为初始、活化或记忆T细胞。我们发现,肺中的T细胞主要产生1型细胞因子反应。大量Th1细胞的出现与潜伏感染的建立同时发生。相比之下,纵隔淋巴结和脾脏中的主要反应是Th2型反应。
