Figure 2. Hepatitis C virus core and NS3 induced toll-like receptor activation. Human conjunctival fibroblasts were exposed to 20 ng/ml of core and NS3 proteins for 6 h. Semiquantitative reverse transcription (RT)–PCR was performed to measure the TLR gene expression. AC: Lanes 1, 18, and 34 represent the 100 bp DNA ladder; lane 2 represents PCR negative control; all the TLRs and GAPDH include PCR products from the control, core, and NS3-treated groups in that order. Data are representative of three independent experiments. D: During the core protein treatment, TLR7 and TLR10 were upregulated, and TLR5 was downregulated. During the NS3 protein treatment, TLR1, TLR9, and TLR10 were upregulated; TLR2 was downregulated, and TLR8 expression was not detected. Data are represented as mean ± standard error of the mean (SEM) over the untreated control group. *p<0.05.
