Figure 4G shows that 28 immune cells were differentially concentrated between the AKI and control groups. Among these, activated CD4 T cells, CD56dim natural killer cells, eosinophils, mast cells, memory B cells, natural killer T cells, neutrophils, T follicular helper cells, and type 1 T helper cells were more enriched in the AKI cluster. This evidence concerns the gene CD4 and acute kidney injury.
