Figure 3. IFNα, but not IFNλ, treatment induces pulmonary cytokine secretion through activation of immune cells.

Figure 3

  • A, B
    IL‐6, IP‐10 and MCP‐1 concentrations were measured by multiplex cytokine assay in AEC culture supernatants (A) and macrophage, pDC and cDC culture supernatants (B) at 24 h post‐stimulation with IFNα4 (0.725 ng/ml) or IFNλ2 (1.3 ng/ml) or LPS (AEC only) (data shown are representative of two independent experiments, n = 3–6).
  • C
    BAL samples taken from mice treated with IFNα, IFNλ or Veh Ctrl at specified time points (data shown are representative of two independent experiments, n = 5–6).
Data information: Significance assessed by unpaired t‐tests where *denotes IFNα:Veh Ctrl and °indicates IFNα:IFNλ. IFNλ:Veh Ctrl was not significant. IL6 pDC: ***P = 0.0004, °°° P = 0.0005, IL6 cDC: *P = 0.0102, ° P = 0.0151. IP‐10 macrophage: **P = 0.0033, °° P = 0.0033, pDC: ****P < 0.0001, °°°° P < 0.0001, cDC: **P = 0.0013, °° P = 0.0013, MCP‐1 macrophage: ****P < 0.0001, °°° P = 0.003 (B). IL‐6 10 h: *P = 0.0112, ° P = 0.0262, 18 h: *P = 0.0314, ° P = 0.373. IP‐10 10 h: *P = 0.0261, ° P = 0.0472. MCP‐1 10 h: **P = 0.0081, ° P = 0.0206, 18 h: **P = 0.0089, ° P = 0.01 (C).
