Fig 4. CD4⁺Foxp3⁺ Tregs in the peritoneal cavity and dendritic cells, NK cells, and macrophages in the lungs of WT and CCR4^-/- mice.

(A) Percentages of CD4⁺Foxp3⁺ Tregs (left panel) and their absolute numbers (right panel) in the peritoneal cavity at 24 h after sham and CLP surgery in the WT and CCR4^-/- mice. (B) The percentages of CD11c⁺ (dendritic cells), NK1.1⁺ (natural killer cells), and F4/80⁺ cells (macrophages) (left panels) and their absolute numbers (right panels) were determined in the lungs of the WT and CCR4^-/- mice at 24 h after sham and CLP surgery. The data are representative of two experiments. *P<0.05 between the L-WT and sham-WT groups.
