Figure Lengend Snippet: Effect of arginine supplementation on the ratio of CD8 + to CD4 + T cells in the spleen of broilers during NE challenge. On d 14, the birds in the NE + Basal, NE + Arg 125%, and NE + Arg 135% groups were orally gavaged with 1 × 10 4 sporulated oocysts of E. maxima and on d 19, 20, and 21, the birds were gavaged with 1 × 10 8 CFU/mL of C. perfringens . The spleen was collected on d 21, 28, and 35, and flow cytometry was performed to evaluate the effect of arginine supplementation on the CD8 + : CD4 + ratio during the NE challenge. Bars (± SEM) with no common superscript differ significantly ( P < 0.05). P -values for D21: P = 0.26, D28: P = 0.01, D35: P < 0.01.
Article Snippet: Single-cell suspensions of cecal tonsil and spleen lymphocytes were obtained and incubated with FITC-conjugated mouse anti-chicken CD4 at 1:250 dilution, PE-conjugated mouse anti-chicken CD8 (Southern Biotech, Birmingham, AL) at 1:450 dilution, and unlabeled mouse IgG at 1:100 dilution in a 96 well plate and incubated for 20 min. Also, single-cell suspensions of cecal tonsil and spleen lymphocytes were incubated with PE-conjugated mouse anti-chicken CD25 (Southern Biotech, Birmingham, AL) at 1:10 dilution and unlabeled mouse IgG at 1:100 dilution in a 96 well plate and incubated for 40 minutes.
