TNF and Guillain-Barre syndrome: Our results showed that the serum levels of IL-36α and IL-36γ in GBS were positively correlated with the serum levels of IL-17 or TNF-α (r = 0.425, P < .01, Fig. 4a; r = 0.474, P < .01, Fig. 4c; r = 0.493, P < .01, Fig. 4e; r = 0.564, P < .01, Fig. 4g, respectively).
