The frequency of CD27 and CD38-expressing populations in CD4⁺ IFN-γ⁺ T cells and in CD4⁺ T cells for the various groups. A CD4⁺IFN-γ⁺CD27⁺ and CD4⁺IFN⁻γ⁺CD27⁻, B CD4⁺IFN⁻γ⁺CD38⁺ and CD4⁺IFN-γ⁺CD38⁻, C CD4⁺IFN⁻γ⁺CD38⁺CD27⁻ and CD4⁺IFN-γ⁺CD27⁺CD38⁻, D CD4⁺IFN⁻γ⁺CD27⁻, E CD4⁺IFN⁻γ⁺CD38⁺, and F CD4⁺IFN⁻γ⁺CD38⁺CD27⁻ in CD4⁺ IFN-γ⁺ T cell in peripheral blood stimulated with ESAT 6/CFP10 were compared in ATB and other groups. The phenotypic markers G CD4⁺IFN⁻γ⁺CD27⁻, H CD4⁺IFN⁻γ⁺CD38⁺, and I CD4⁺IFN⁻γ⁺CD38⁺CD27⁻ on CD4⁺ T cell in peripheral blood stimulated with ESAT 6/CFP10 in each group was compared. ATB active tuberculosis, LTBI latent tuberculosis infection, NTM non-tuberculous mycobacterium pulmonary disease, OD other respiratory diseases, HC healthy control
