Figure Lengend Snippet: ( A ) Time-kill curves of E. coli Ec MCR1 + and Kp10 strains in the presence of 2xMIC ENOblock for 24 h. ( B ) Membrane permeabilization of E. coli Ec MCR1 + and Kp10 strains in the presence of 0.5xMIC ENOblock, incubated for 10 min, was quantified by Typhon Scanner. Data are represented as mean ± SEM from three independent replicates and experiments. * P = 0.001: Ec MCR1 + vs Ec MCR1 + + ENOblock(two-tailed Student’s t test). ( C ) Analysis of E. coli Ec MCR1 + and Kp10 strains adhesion into HeLa cells with (1xMIC) and without ENOblock treatment. The data are presented as means ± SEM, * P = 0.015: Ec MCR1 + vs Ec MCR1 + + ENOblock and * P = 0.02: Kp10 vs Kp10 + ENOblock (two-tailed Student’s t test). Analysis of E. coli Ec MCR1 + and Kp10 strains invasion into HeLa cells with (1xMIC) and without ENOblock treatment. The data are presented as means ± SEM, * P = 0.002: Ec MCR1 + vs Ec MCR1 + + ENOblock and * P = 0.037: Kp10 vs Kp10 + ENOblock treatment (two-tailed Student’s t test).

Figure Lengend Snippet: ( A ) Schematic of the bacterial adhesion/invasion assay. ( B ) Analysis of Ab ATCC 17978 and Ab CR17 strains adhesion into HeLa and macrophage cells with (1xMIC) and without ENOblock treatment. The data are presented as means of three biological replicates ± SEM, For HeLa cells, * P = 0.023: Ab ATCC 17978 vs Ab ATCC 17978 + ENOblock and * P = 0.048: Ab CR17 vs Ab CR17 + ENOblock (two-tailed Student’s t test). For macrophage cells, * P = 0.018: Ab ATCC 17978 vs Ab ATCC 17978 + ENOblock and * P = 0.035: Ab CR17 vs Ab CR17 + ENOblock (two-tailed Student’s t test). ( C ) Analysis of Ab ATCC 17978 and Ab CR17 strains invasion into HeLa and macrophage cells with (1×MIC) and without ENOblock treatment. The data are presented as means of three biological replicates ± SEM, For HeLa cells, * P = 0.001: Ab ATCC 17978 vs Ab ATCC 17978 + ENOblock and * P = 0.011: Ab CR17 vs Ab CR17 + ENOblock (two-tailed Student’s t test). For macrophage cells, * P = 0.001: Ab ATCC 17978 vs Ab ATCC 17978 + ENOblock and * P = 0.002: Ab CR17 vs Ab CR17 + ENOblock (two-tailed Student’s t test). ( D ) Immunostaining of fibronectin of HeLa cells (magenta) and Ab ATCC 17978 and Ab CR17 strains (green) pretreated with ENOblock (0× and 1×MIC), after bacterial adherence for 2 h, was performed by specific primary antibodies against both strains and their respective secondary antibodies. Blue staining shows the location of HeLa cell nuclei. A representative image out of three biological replicates is shown. .

Figure Lengend Snippet: ( A ) PCA plot of TMT data from Ab infected macrophages and epithelial cells of three biological replicates each group. ( B ) Venn diagrams showing the overlap of DEGs between the two comparisons: Ab infected macrophages vs Ab infected epithelial cells. The upper panel shows overlaps of overexpressed proteins, while the lower panel shows overlaps of downexpressed proteins. A total of six proteins were found to be commonly overexpressed in Ab upon exposure to both epithelial and macrophage cells: enolase, tyrosine–tRNA ligase, malonyl-CoA:acyl carrier protein transacylase, N-succinylarginine dihydrolase, carbonic anhydrase, and biotin carboxylase. Additionally, one protein, isocitrate dehydrogenase, was consistently downregulated in response to both cell types. ( C ) COG category distribution of DEPs. The overexpressed and downexpressed proteins in each comparison are categorized by their COG functional groups, with blue representing downexpressed proteins and orange representing overexpressed proteins. ( D ) Volcano plots depicting the DEPs for the two comparisons. Proteins significantly overexpressed are shown in red, while significantly downexpressed proteins are shown in blue. Enolase overexpression is shown in green. Non-significant proteins are indicated in black. Three biological replicates from each group were compared. ( E ) A. baumannii Ab ATCC 17978 and Δ eno strains, with or without supplementation of 4 mM phosphoenolpyruvate, adhesion to HeLa cells. The data are presented as means of three biological replicates ± SEM, and Student t test was used for statistical analysis. * P = 0.006: Ab ATCC 17978 vs Δ eno and * P < 0.001: Ab ATCC 17978 vs Δ eno + PEP (two-tailed Student’s t test).
