Figure Lengend Snippet: Cytokines secreted by THP-1 cells. THP-1 cells were stimulated with PRN − , FHA − , FHA − PRN − , and WT isolates at an MOI of 10 or left unstimulated for 24, 48, and 72 h. Production of (A) IL-1β, (B) IL-6, (C) IL-12, (D) MCP-1, (E) CXCL2, and (F) G-CSF in the supernatant was determined by ELISA ( n = 3 ∼ 4). Results are shown as means and standard deviations. Brackets indicate individual comparisons of each mutant strain versus the WT control. Statistical significance was determined using two-way ANOVA followed by Dunnett’s multiple comparisons test; * p < 0.05; ** p < 0.01; *** p < 0.001; **** p < 0.0001; ns, not significant.
Article Snippet: THP-1 cells (ATCC TIB 202; Supplementary Table 3) were seeded in 12-well (8.0 × 10 5 cells/well) culture plates (712012; NEST, China) and incubated overnight in RPMI 1640 medium (C11875500BT; Gibco, USA) supplemented with 2% FBS without antibiotics.
