IL-6 prevents GSDME- and GSDMD-mediated lung inflammation injury during pneumococcal pneumosepsis. (A and B) Caspase-3 (n = 4/group), GSDME (n = 4/group), IL-1β (n = 4/group), and (C and D) caspase-1 (n = 4/group), GSDMD (n = 4/group), and IL-18 (n = 4/group) in lungs of mice with or without IL-6 protein treatment during pneumococcal pneumosepsis, as indicated. IL-1β and TNF-α in (E) lung homogenates (n = 6/group) and (F) BALF (n = 5 to 6/group) of mice with or without IL-6 protein treatment during pneumococcal pneumosepsis, as indicated. (G to I) Lung inflammation injury in mice with or without IL-6 protein treatment was assessed in situ using (G) a commercial cell death detection kit (n = 3/group), (H) H&E staining (n = 3/group), and (I) total protein in BALF (n = 4 to 7/group) during pneumococcal pneumosepsis.
