Susceptibility to pulmonary disease due to Mycobacterium avium-intracellulare complex may reflect low IL-17 and high IL-10 responses rather than Th1 deficiency

Abstract It remains unclear why some individuals and not others are susceptible to non-tuberculous mycobacterial lung disease (NTMLD). To determine whether NTMLD is associated with defects or biases in Th1/Th2/Th17 immunity, blood leukocytes from NTM patients with nodular bronchiectasis, their adult offspring, and healthy population controls were stimulated with staphylococcal enterotoxin B (SEB), tuberculin and sensitin to measure cytokine production. In response to SEB, NTM patients exhibited higher frequencies of IFNγ-producing CD4 + T cells than population controls ( P P P P + T cells were undetectable. NTMLD is not associated with deficient IFNγ production, but may be associated with reduced Th17 immunity and/or a predisposition towards IL-10 production from non-CD4 + T cells.
