Transcriptomic analysis of blood samples from LTBI versus noninfected individuals showed a lower frequency of MR1tet+ CD8+ cells in LTBI (Pomaznoy et al., 2020), but in another study, the correlation between blood MAIT frequency and TB status was completely absent for both active and latent TB individuals (Suliman et al., 2020). This evidence concerns the gene CD8A and tuberculosis.
