NKp46⁺ NKG2A⁺ NK cells ameliorated PR8 infection in mice with lung fibrosis. (A) Protocol of NK cell adoptive transfer in mice suffering lung inflammation caused by bleomycin. (B) Weight change and survival of mice. Data shown as means ± SEMs and represent 3 independent experiments; n = 5. (C) Hematoxylin and eosin staining and histopathological scores of a bleomycin-induced lung inflammation model treated with different NK cell subsets; n = 5. Data shown as means ± SEMs and represent 3 independent experiments. *, P < 0.05; **, P < 0.01.
