TGF-β1 expression was positive correlated with TREM-1 upregulation in mouse lungs.
The mRNA levels of TGF-β1 (a) and TREM-1 (b) in mouse lungs were detected by real-time PCR. The correlation between TGF-β1 and TREM-1 (c) was analyzed by Pearson correlation analysis and the correlation coefficient was 0.787, p < 0.01. The controls for each time-point were normalized as 1 in (e). Expression of TREM-1 protein (d,e) in lung tissues was detected by Western blot. Data were expressed as the mean ± SD with 8 mice per group, **p < 0.01.
