Figure 1. TLR2 and TLR4 mRNA expression in hydrocortisone-treated HCF. TLR2 and TLR4 mRNA expression in three concentrations of hydrocortisone-treated HCFs, compared with untreated HCFs. Bars represent mean±SEM of 3 independent experiments. The asterisk represents a p value of <0.05, versus the control.
