Effect of dietary abscisic (ABA)-supplementation on lymphocyte subsets in blood, spleen and mesenteric lymph nodes (MLN) of mice with intestinal epithelial cell-specific PPARγ deficiency (VC+) and PPARγ expressing (VC−) mice. Percentages of CD4+CD25+FoxP3+ T cells in blood (A), spleen (B), and MLN (C). Percentages of CD4+CD44+ T cells in blood (D) and spleen (E). Significant effects (P<0.05) of genotype (G) by diet (D) interaction and the main effects of D are shown. Values are means ± SEM, n = 10. Means without a common letter differ, P<0.05.
