Phenotypic analysis of PBL.

<p>(<b>A</b>) Representative dot plots of phenotypes in PBL expressing CD8α and CD161 molecules in rats fed the control diet. (<b>B</b>) The percentage of CD8⁺ CD161⁻, CD8⁻CD161⁺, and CD8⁺CD161⁺ cells in the CD45⁺ cell populations. Significant differences between rats with or without DSS treatment were determined by an unpaired two-tailed Student’s <i>t</i>-test (*<i>P</i><0.05, ***<i>P</i><0.001). Values are expressed as means ± SEM (n = 3–5).
