Figure Lengend Snippet: Chemoattraction of basophils upon TBI occurs through CXCL1 expression in B-cells and DCs. A Principal component analysis (PCA) of the cytokine array revealed distinct clustering of the sham and TBI treatment groups. N = 5. B The heatmap of the cytokine array showed the significantly altered cytokines/chemokines in the spleen 3 h after TBI. N = 5. C Principal component analysis (PCA) of the vascular factors array revealed distinct clustering of the sham and TBI treatment groups. N = 6. D The heatmap of the vascular factors array showed the significantly altered cytokines/chemokines in the spleen 3 h after TBI. N = 6. E - H ELISA assays verification, in a larger subset of samples, showed the significant upregulation of CXCL1 (Sham vs TBI: 2642±1403 pg/ml vs 4439±1451 pg/ml; p = 0.0090; t = 2.893) and CCL6 (Sham vs TBI: 19466±3209 pg/ml vs 26175±6681 pg/ml; p = 0.0083; t = 2.916), a significant downregulation of IL-5 (Sham vs TBI: 1146±637 pg/ml vs 654±337 pg/ml; p = 0.0331; t = 2.298) and no difference in CXCL13 in the spleen. Plasma samples showed the significant upregulation only in CXCL1 (Sham vs TBI: 116±92 pg/ml vs 408±264 pg/ml; p = 0.0018; t = 3.387), with no differences observed in CXCL13, CCL6 and IL-5. Sham N = 10; TBI N = 13. I - L Single mRNA RNAscope revealed the significant increase of CXCL1 mRNA puncta in the whole spleen (Sham vs TBI: 47±7 vs 59±9; p = 0.0377; t = 2.488), as well as an increase of CXCL1+/CD19+ (magenta dotted outline; sham vs TBI: 11±4% vs 23±6%; p = 0.0033; t = 4.125) and CXCL1+/CD11c+ (yellow dotted outline; sham vs TBI: 15±4% vs 28±3%; p = 0.0006; t = 5.484) cells after TBI.

Figure Lengend Snippet: Ethanol pretreatment prevents the chemotaxis of basophils to the spleen. A , B Immunofluorescence staining of spleen sections with CD19 and MCPT8 show a significant increase in MCPT8+ cells (white dotted outline) post TBI in the germinal center (SS vs ST: 8±1 vs 18±4; p = 0.0047) and marginal zone (SS vs ST: 11±1 vs 27±4; p < 0.0001) of splenic follicles. With a significant decrease in MCPT8+ cells with ethanol pretreatment, in both the germinal center (ST vs ET: 18±4 vs 8±3; p = 0.0032) as well as the marginal zone (ST vs ET: 27±4 vs 14±4; p = 0.0002).
