The expression of IFN-γ and TNF-α in CD3⁺ and CD4⁺ T cells. (a, b) IFN-γ⁺CD4⁺ T cell in the lungs and spleens of Ctnnb1^−/− mice (n = 5) and wild-type mice (n = 5) infected with or without M. tuberculosis. (c, d) TNF-α⁺CD4⁺ T cell in lungs and spleens of Ctnnb1^−/− mice (n = 5) and wild-type mice (n = 5) infected with or without M. tuberculosis. (e, f) CD69⁺CD3⁺CD4⁺ T cells in the lungs and spleens from Ctnnb1^−/− mice (n = 5) and wild-type mice (n = 5) infected with or without M. tuberculosis. (g, i) mRNA of IFN-γ, TNF-α, and TCF-7 in the lungs of Ctnnb1^−/− mice (n = 5) and wild-type mice (n = 5) infected with or without M. tuberculosis. The experiment had three independent rounds, and results were analyzed by the unpaired Student t-test. PBS, phosphate-buffered saline.
