We evaluated IFN-γ CD8+ T cell responses to five novel Mtb antigens in 108 TB-positive subjects from Uganda using ELISPOT. While categorical response thresholds showed no significant association with TB phenotype, quantitative analysis revealed significantly higher IFN-γ responses to four antigens in ATB versus LTBI (p ≤ 0.015). These findings suggest continuous CD8+ T cell IFN-γ responses correlate with bacillary burden and may inform TB diagnostics and vaccine development.}, url = {http://digitalcollections.ohsu.edu/record/776}, doi = {https://doi.org/10.6083/M4BG2M0Z}, }
