Percentage of T lymphocyte subsets in peripheral blood of HP-PRRSV infected and non-infected piglets. Piglets were infected with HP-PRRSV and blood was harvested after infection at 0, 3, 7, 10, 14, 18 and 21dpi. Single cell suspensions were prepared and stained with antibodies against T lymphocytes markers CD3, CD4, and CD8 and analyzed by flow cytometry. Representative flow cytometric plots of T lymphocytes are shown in the blood. The detailed analysis for CD3+ T lymphocytes are presented (a), CD4+ T lymphocytes (b), CD8+ T lymphocytes (c) and ratio of CD4+/CD8+ T lymphocytes (d). Data are shown as means ± SD. Asterisks indicate significant differences between the indicated experimental groups (*p < 0.05, **p < 0.01). Note: The CD4+ and CD8+ population are represented CD4+ CD8-cells and CD8+ CD4- respectively only
