(A–C) IL-1β production by Pam3CSK4-primed C57BL/6 wild-type and Trif−/− (A) or Ifnar1−/− (B) or caspase-11−/− (C) BMDMs stimulated with indicated bacteria for 16 hr.
(D) Cleaved caspase-1 and IL-1β in the supernatants of Pam3CSK4-primed BMDMs stimulated with indicated bacteria for 16 hr.
(E) IL-1β secretion by Pam3CSK4-primed C57BL/6 wild-type and Trif−/− BMDMs stimulated with P. aeruginosa PAK wild-type strain or pscC mutant strain (that lacks the type III secretion system) for 16 hr.
(F) Secreted and cleaved IL-1β in the supernatants of BMDMs primed as indicated and stimulated with cholera toxin B for 16 hr.
Data are presented as the mean ± SEM of one experiment representative of 2–3 experiments. See also Figure S5 and Table S1.
