Figure 7 shows the proteomics data (Figure 7A) alongside representative images of antibody-labeled NETs (Figure 7B). The abundance of SERPIN1B on PMA-induced NETs from RA patients correlated with RA disease activity (DAS28) scores (R2 = 0.84, p = 0.029). DAS28 also correlated significantly with phosphoglycerate kinase-1 (PGK1, R2 = 0.74, p = 0.028) and histone H1 family member 0 (H1F0, R2 = 0.68, p = 0.044) in A23187-induced RA NETs. Here, PGK1 is linked to rheumatoid arthritis.
