CD177 cell surface level expression is higher in ACLF versus CLD. (A) Gating strategy for assessment of CD17+ cells by flow cytometry. Neutrophil enrichment was determined by CD66b+ and CD16+positivity. The first plot represents an FSC versus SSC scatter plot, used for gating PMN cells. Singlets gating as determined by FSC-height v/s FSC-area plot. This is followed by a quadrant plot for CD66b-FITC versus CD16-APC, and double positive neutrophils are gated on Q2. The last quadrant plot represents CD177-APC-Cy7 versus CD16-APC. CD177 positive cells are gated. (B) CD66b+CD16+ positive neutrophil percentage across groups. The mean percentage of enrichment is significantly different across groups as determined by Kruskal Wallis test (C) CD177 positive cell percentage across study groups. The mean CD177 population was found to be significantly different across the three groups, as calculated by one-way ANOVA. Pairwise analysis for CD177 + cell percentages were performed for ACLF versus CLD. *p value ≤ 0.05; ** p value ≤ 0.005, ***p value ≤ 0.001.
