FIG. 4.
Expression of Th1, Th2, and Treg genes in the liver tissue of pigs infected with A. suum and treated with ATRA. Real-time PCR detection of mRNA expression (CT values) for selected genes associated with Th1 or Th2 cells or Tregs in the livers of pigs infected with A. suum and treated with two different doses of ATRA is shown. Tissue mRNA expression (CT values) at 7 or 14 days after inoculation was evaluated by one-way ANOVA. n-fold changes relative to results for control pigs are designated by color differences, shown in the figure insert, and statistical significance by A (P < 0.05) or B (P < 0.01).
