Blood samples were obtained by cardiac puncture and collected in heparinized tubes [36 (
link),60 (
link)]. BAL samples were obtained according to the technique developed in the Laboratory Immunobiotechnology of CERELA-CONICET (San Miguel de Tucuman, Argentina) [38 (
link),61 (
link)]. The trachea was exposed and intubated with a catheter, and then two sequential bronchoalveolar lavages were performed on each mouse by injecting sterile PBS. The recovered fluid was centrifuged for 10 min at 900×
g and the fluid frozen at −70 °C for subsequent cytokine determinations. Tumor necrosis factor alpha (TNF-α), interferon gamma (IFN-γ), interleukin 10 (IL-10), IL-1β, IL-6, IL-17, KC, and monocyte chemoattractant protein 1 (MCP-1) concentrations were determined in serum and BAL samples using commercial ELISA kits. IFN-γ (
Mouse IFN-gamma Quantikine ELISA Kit, sensitivity: 2 pg/mL), IL-10 (
Mouse IL-10 Quantikine ELISA Kit, sensitivity: 5.2 pg/mL), IL-1β (
Mouse IL-1β DuoSet ELISA, sensitivity: 1.5 pg/mL), IL-6 (
Mouse IL-6 Quantikine ELISA Kit, sensitivity: 1.8 pg/mL), and IL-17 (
Mouse IL-17 Quantikine ELISA Kit, sensitivity: 4.7 pg/mL) from R&D Systems (USA). TNF-α (
Mouse TNF alpha ELISA Kit, sensitivity: 9.1 pg/mL), MCP-1 (
Mouse MCP1 ELISA Kit, sensitivity: 0.487 pg/mL), and KC (Mouse KC ELISA Kit, sensitivity: 1.95 pg/mL) kits were obtained from Abcam (Cambridge, UK).
