Wild type and Nlrx1-/- mice were irradiated and replenished with bone marrow from healthy wild type or Nlrx1-/- mice. Mice were allowed to recover for 6–8 weeks prior to inoculation. (A) Kaplan-Meier survival curve for neutrophil depleted chimeric mice inoculated with AF293 via non-invasive tracheal instillation AF293 conidia (107 conidia/ 25μL). Mice were immuno-suppressed on day 1 prior and day 3 post inoculation using IP injection of Ly6G antibody (Clone A18). Statistical significance was determined using the log-rank (Mantel-Cox) test. N = 10 experimental group. (B-F) FACS analysis of immune cell populations from bronchoalveolar lavage fluid BALF and pulmonary tissue from immuno-competent chimeric mice on day 1 post inoculation were determined by FACS. Asterisk denotes statistical significance, P < 0.05 Mann-Whitney U test. Error bars indicate standard deviation. N = 8–10 per experimental group. AM, alveolar macrophages. IM, interstitial macrophages. DC, dendritic cells. pDC, plasmocytoid dendritic cells. moDC, monocytoid dendritic cells. cDC, conventional dendritic cells. NK, natural killer cells. NKT, natural killer T cells. CD8+, CD8+ T cells. CD4+, CD4+ T cells.
