IL17A and Klebsiella Infections: Although lung-resident innate-like T cells did not constitutively express IL-17A as assessed by the hNGFR reporter, γδ T cells, iNKT cells and other CD3ε+ cells expressed hNGFR within 24 hr after Klebsiella infection or 8 hr after administration of IL-1β and/or IL-23.
