| Research Abstract |
We generated the CCL1 (NCBI: rs2282691) transgenic mice using surfactant protein C promoter (SPC-CCL1 Tg), which overexpressed CCL1 gene in the lungs. We developed the Mycobacterium bovis Bacillus Calmette Guérin (BCG) infection models in SPC-CCL1 Tg mice.
Microscopic observation revealed that the numbers of granulomas in the lungs were significantly increased in SPC-CCL1 Tg mice. In DNA microarray analyses, 4,569 genes had 3 times and higher or one third and lower expression in the lung of Tg mice compare to that of WT mouse. Hierarchical cluster analysis of those genes revealed that Ern1, that plays important roles in endoplasmic reticulum stress and in granuloma formation, was more upregulated in the lung of BCG-treated SPC-CCL1 Tg mice compared to that of wild type mice.CCL1 overexpression increased the formation of granulomas upon BCG infection in the lungs. SPC-CCL1 Tg mice showed significant gene expression of Ern1 in comparison with wild type mice.
