Figure 1. CD8+ T-cell frequencies in tissues of LPAIV infected chickens.
Percentages of CD8αα+CD3+ T cells (A–C) and CD8βα+CD3+ T cells (D–F) were analysed by flowcytometry in lung, spleen and PBMC at several days post infection. Absolute numbers were calculated by multiplying the percentage of CD8αα+CD3+ T or CD8βα+CD3+ T cells with the total number of cells isolated from lung (G, I) and spleen (H, J). Mean plus SEM is shown. In white: uninfected controls (UNINF, n = 12), in grey infected birds (n = 3 per time point).
