T lymphocyte subsets induced by immunization with rHVT-<i>pmpD</i>-N and parental HVT.

<p>T cells were purified from the blood of immunized chickens (<i>n</i> = 5 for each group) on day 35. The values were shown as dot plots and means. (A) The proportion of T cell subsets in PBLs by flow cytometric analysis. ^a–bBars in the same T lymphocyte subsets with the different superscripts indicate significantly different among three groups. (B) The ratio of CD4+/CD8+ among three groups. ^a–bBars with the different superscripts indicate statistically significant difference among three groups.
