In line with recent studies that have found MAIT cell expansions in the lungs of mice experimentally infected with Mtb36 and S. enterica serovar Typhimurium (S. Typhimurium)37, we found expansions of TRAV1-2+ CD8+ T cells with MAIT or MAIT-like features in the BAL and lung parenchyma in patients with TB. Here, CD8A is linked to tuberculosis.
