Figure Lengend Snippet: Neutralization of ACBP/DBI combined with dexamethasone enhances protection against LPS-induced challenge and CLP-induced sepsis in mice. a Twelve-week-old male C57BL/6J mice were treated with monoclonal antibody against ACBP/DBI (α-ACBP; 5 mg/kg, i.p.) twice, in combination with one dose of dexamethasone (DEX; 10 mg/kg, i.p.) during the week prior to LPS challenge. Additionally, two doses of α-ACBP (2.5 mg/kg) and one dose of DEX (10 mg/kg) were administered 4 h or 1 h before LPS injection. b Survival was monitored in LPS-challenged mice ( n = 20 per group). The p value from the log-rank test is shown. c Plasma levels of 42 cytokines were measured at 6 h post-LPS challenge using a proximity extension assay. Cytokine expression was compared among groups treated with α-ACBP, DEX, both, or vehicle. Statistical comparisons were performed by two-way ANOVA with FDR correction for multiple comparisons on log2-normalized cytokine data. d Nine-week-old male C57BL/6J mice were treated with α-ACBP (2.5 mg/kg, i.p.) twice in combination with one dose of DEX (10 mg/kg, i.p.) 1 h prior to sham or CLP surgery. e Survival was monitored over time (n = 15–20 per group). The p value of the log-rank test is indicated. f Body temperature was recorded 24 h post-surgery. g Murine Sepsis Score (MSS) was assessed on a scale of 0 to 4 based on multiple clinical parameters—appearance (App), respiration quality (RQ), respiration rate (RR), eyes, level of consciousness (LOC), activity, and response to stimulus (RTS)—by two independent examiners. Scores were averaged per mouse and depicted as Z-scores in a heatmap analyzed by two-way ANOVA with FDR correction. h Individual MSS values are shown. i Venn diagram illustrating overlap among upregulated differentially expressed genes (DEGs) in spleens from CLP mice, categorizing genes reversed by α-ACBP alone, by DEX alone, or specifically by the combination treatment. j Venn diagram showing overlap of downregulated DEGs in the same groups. Data are presented as means ± SEM. Statistical comparisons were performed using one-way ANOVA ( h ) and two-way ANOVA ( f ) with estimation of marginal means for pairwise comparisons. il1b interleukin-1 beta, ifnl2 interferon lambda 2, il9 interleukin-9, il17f interleukin-17f, ifng interferon gamma, il17a interleukin-17a, ccl17 c-c motif chemokine ligand 17, cxcl1 c-x-c motif chemokine ligand 1, csf3 colony stimulating factor 3, il16 interleukin-16, ccl2 c-c motif chemokine ligand 2, il21 interleukin-21, cxcl12 c-x-c motif chemokine ligand 12, il7 interleukin-7, cxcl11 c-x-c motif chemokine ligand 11, il31 interleukin-31, il2 interleukin-2, il33 interleukin-33, csf1 colony stimulating factor 1, cxcl9 c-x-c motif chemokine ligand 9, ccl4 c-c motif chemokine ligand 4, hgf hepatocyte growth factor, il10 interleukin-10, il1a interleukin-1 alpha, ccl11 c-c motif chemokine ligand 11, csf2 colony stimulating factor 2, il-4 interleukin-4, ctla4 cytotoxic t-lymphocyte associated protein 4, ccl22 c-c motif chemokine ligand 22, il3 interleukin-3, cd274 cluster of differentiation 274 (pd-l1), pdcd1lg2 programmed cell death 1 ligand 2 (pd-l2), cxcl2 c-x-c motif chemokine ligand 2, ccl5 c-c motif chemokine ligand 5, fgf21 fibroblast growth factor 21, il5 interleukin-5, tnf tumor necrosis factor, il12a_il12b interleukin-12 subunits (p35 and p40), il-6 interleukin-6, il22 interleukin-22, il27 interleukin-27, ifna2 interferon alpha 2
