Figure 3From: Expression of human beta-defensins 1 and 2 in kidneys with chronic bacterial infectionCultured CAL-54 cells were stimulated with increasing TNFα (Fig. 3a), IL-1β (Fig. 3b), and LPS (Fig. 3c) concentrations for 6 hours in FCS-free medium. HBD-1 mRNA expression was analyzed by real-time RT-PCR. Bars represent the relative HBD-1 transcript levels normalized to GAPDH transcript levels.Back to article page
