Our study reveals the crucial role of gammadelta T cells in non-tuberculous mycobacteria (NTM) infection. We observed a significant increase and activation of gammadelta T cells in mice infected with MAB or with MAB infection combined with pulmonary fibrosis. Depletion of gammadelta T cells worsened the infection, while transfer of gammadelta T cells reversed this effect. Mechanistically, we found that MAB infection stimulates macrophages to produce IL-1beta and IL-23, which promotes the expansion of gammadelta T17 cells. MAB can also directly activate gammadelta T cells, leading to the clearance of MAB through an IL-17A-dependent pathway. Our findings suggest that gammadelta T cells represent a potential therapeutic target for NTM infections.2026/06/01GSE329046GSM9696296GSM9696294GSM969629524247329046Mus musculus
