Fig. 2From: IL-8 and IP-10 expression from human bronchial epithelial cells BEAS-2B are promoted by Streptococcus pneumoniae endopeptidase O (PepO)Effects of PepO on TLRs triggering in BEAS-2B. Quantitative RT-PCR were used to determine TLR2 and TLR4 mRNA in BEAS-2B activated by PepO (10 μg /ml) for indicated times; Results are expressed as the mean ± SD (n = 3). Student’s t-test was performed to calculate the statistical significance (**p < 0.01 or ***p < 0.001)Back to article page
