Figure 5: Effector memory CD4⁺ T cells displayed the highest frequency of Nrp1⁺oxLDL⁺ T cells.

Representative contour plots of dil-oxLDL by Nrp1 for B6 T_N, T_CM, and T_EM subsets, in addition to ApoE^−/− T_EM cells (A, C, E) and pooled frequencies of Nrp1⁺oxLDL⁺ T cells, gated on CD4⁺TCRβ⁺ T cells (B), Foxp3⁻CD4⁺TCRβ⁺ T cells (D), and Foxp3⁺CD4⁺TCRβ⁺ T cells (F). Representative contour plots of CD25 by Foxp3, gated on CD4⁺TCRβ⁺ T cells (G) and pooled frequencies of CD25⁺Foxp3⁺ Tregs (H). Results are expressed as the mean + s.e.m. from one independent experiment. Statistically significant differences were at *P < 0.05, ***P < 0.001, and ****P < 0.0001.
