The percentages of T-cell subpopulations within PBLs of LEW.1AR1 and LEW.1AR1-<i>iddm</i> rats (d. = diabetic animals; n.d. = non-diabetic animals).

<p>The percentages of (A) CD3⁺, (B) CD4⁺, (C) CD8⁺ T-cells, and (D) CD4⁺/CD8⁺ T-cell ratio were determined in PBLs by flow cytometric analysis from rats at an age between 35 and 110 days. Each symbol represents the T-cell value for a single animal. The number of animals was for LEW.1AR1 (n = 12), LEW.1AR1-<i>iddm</i> diabetic (n = 34) and LEW.1AR1-<i>iddm</i> non-diabetic (n = 32). The mean values for the different groups are represented by the horizontal bar in the graphs and were compared statistically. **p<0.01/***p<0.0001 LEW.1AR1 compared to LEW.1AR1-<i>iddm</i>, ^§p<0.05 diabetic compared to non-diabetic LEW.1AR1-<i>iddm</i> rats, and ^##p<0.01/^###p<0.0001 for range of percentage LEW.1AR1 group compared to LEW.1AR1-<i>iddm</i> group, (ANOVA plus Tukey’s post test).
