TNF and periodontitis: Correlation analysis between in vitro and ex vivo profiles of cytokines confirmed correspondence between healthy neutrophils stimulated in vitro by LPS with sepsis neutrophils (R2 = 0.83), TNF-α−pre-activated neutrophils with NMOSD neutrophils (R2 = 0.67), and IL-10-stimulated neutrophils with periodontitis neutrophils (R2 = 0.77) (Figure S6A and Table S1A vs. S1B in Supplementary Material).
