The number and proportion of CD4⁺and CD8⁺ T cells are abnormal in the blood and immune organs of ALV-J-infected chickens. A FACS analysis strategy for CD4⁺ and CD8⁺ T cells in immune organs. B Quantitation of the frequency of CD4⁺ and CD8⁺ T cells in immune organs. C FACS analysis strategy for CD4⁺ and CD8⁺ T cells in blood. D Quantitation of the frequency of CD4⁺ and CD8⁺ T cells in blood. *p < 0.05, **p < 0.01, ***p < 0.001, the unpaired t-test was performed, and the data were expressed as the mean ± SEM.
