The results demonstrated that the levels of PAD4 (Figure 2F), RELA (Figure 2G), PKC (Figure 2H), SYK (Figure 2I) and ERK (Figure 2J) gene expression were signifFicantly increased after healthy neutrophils were incubated with the plasma of COVID-19 patients (p < 0.05). Here, RELA is linked to COVID-19.
