Figure Lengend Snippet: Representative histogram of the gating protocol used on the enriched chicken peripheral blood lymphocytes stained with PE-CD4 and FITC CD-8. The cells were first gated based on the size (FSC-H) and granularity (SSC-H) (A) . The single cell population was then gated from the histogram (A) based on the cell area (SSC-A) and the cell height (SSC-H) (Fig. 1B). Singlet cells identified in (B) were then analyzed for PE-CD4 and FITC-CD8 staining (C) .

Article Snippet: In brief, 100 μL of the isolated cells were incubated with CD4 (mouse anti-chicken CD4-PE; SouthernBiotech, Birmingham, AL) and CD8 (mouse anti-chicken CD8a-FITC; SouthernBiotech, Birmingham, AL) antibodies.

Figure Lengend Snippet: Effect of the inclusion of phytogenic feed additive A. annua in the diets of laying hens on their peripheral mononuclear blood cell count and CD4 + and CD8 + T cell population 14 days post- Eimeria challenge. At 25 weeks of age, 12,500 E. maxima , 12,500 E. maxima , and 62,500 E. tenella oocysts were inoculated in laying hens grouped into challenged control, 0.5% A. annua , and 1% A. annua . NC: non-challenged control; PF: pair-fed control; CC: challenged control (12,500 E. maxima ; 12,500 E. tenella ; and 62,500 E. acervulina oocysts per mL); 0.5AA: challenged control with the inclusion of 0.5% A. annua in the diet; 1AA: challenged control with the inclusion of 1% A. annua in the diet; dpi: days post-inoculation of Eimeria spp.

Effects of rEmHPSP-2 and rEmHPSP-3 on the transcription of IFN-g and IL-2 in chicken CD8+ T cells (A) Effects of rEmHPSP-2 on the transcription of IFN-g and IL-2 in chicken CD8+ T cells. (B) Effects of rEmHPSP-3 on the transcription of IFN-g and IL-2 in chicken CD8+ T cells. The differences between groups were analyzed using Duncan method of 1-way ANOVA, where the same letter indicates no significant differ- ence (P > 0.05) and different letter indicates significant difference (P < 0.05).

CD8+ T cells were stained with dark brown (indicated with black arrows). Scale bar = 50 µm.

Article Snippet: The tissue sections were then incubated overnight with mouse anti-chicken CD8a (Southern Biotech, Birmingham, AL, USA) diluted 1:100 in 2.5% goat serum at 4 °C.

Figure Lengend Snippet: Image analysis of CD8+ T cells in trachea, lung, kidney, cecal tonsil, ovary, magnum, isthmus, and uterus collected at 12 days following infection with the IBV/Ck/Can/17–036,989 strain. The percentages of CD8+ T cells were compared between all experimental groups using 1-way ANOVA followed by Tukey's multiple comparisons test, and the error bars represent the SD. Significant differences are denoted by different letters above the bars ( P < 0.05).
