The density of lymphocytes in spiral arteries (the ratio of immune positive lymphocytes to endovascular lining cells). Spiral artery was classified into three groups, acute atherosis, non-remodeled muscular artery, and remodeled artery. (a) In cases of HDP with AA. Box-plot graphs show that the density of CD3+, CD8+, CD4 + T cells in AA is significantly higher than those in non-RA. The density of CD56 + NK cells is no significantly different AA and non-RA. (b) In cases of HDP with AA, comparison of non-RA and RA. Box-plot graphs show that the density of CD3+, CD8+, CD4 + T cells and CD56 + NK cells in non-RA is significantly higher than those around RA. (c) In control cases. Box plot graph show that the density of CD3+, CD4 + T cells in non-RA is significantly higher than those in RA. The density of CD8 + T cells and CD56 + NK cells is not significantly different between those arteries. (d) Comparison of HDP with AA cases and control cases in non-RA. Box plot graphs show that significantly different in only density of CD56 + NK cells. (e) Comparison of HDP with AA cases and control cases in RA. Box plot graphs show that the density of CD3 + T cells and CD56 + NK cells is no significantly different between HDP with AA and control cases
