FIG 6.

Decreased inflammatory response in pHepc-treated macrophages. Cells were infected with Salmonella or treated with pHepc as described in the legend to Fig. 4B. The levels of TNF-α (A), IL-1α (B), IL-8 (C), and IL-6 (D) mRNA were determined by quantitative reverse transcription-PCR. 18S rRNA was used as the housekeeping gene. The mRNA expression ratio was normalized to the mean value for unstimulated control macrophages, which was equal to 1. Error bars indicate SEs. *, P < 0.05.
