The analysis demonstrated that there is a significant correlation (p = 0.001387 and Pearson R = 0.7877) between the expression value of ELANE and the number of neutrophils, suggesting that any amount of ELANE upregulation could increase the number of neutrophils in the PBMC of SARS patients in an ELANE expression-dependent manner (Figure 8). Here, ELANE is linked to severe acute respiratory syndrome.
