IL22 and Guillain-Barre syndrome: Our data revealed that Th22 cells were correlated with GDSs (r = 0.399, P = 0.032) (Figure 3(h)), though there was no quantitative uniqueness for the frequency of CD4+IL-22+ cells with GBS severity; the elevated CD4+IL-22+ cells had a tendency for disease severity status in GBS (r = 0.160, P = 0.405) (Figure 3(c)); no other cells were correlated with GDSs (Figures 3(a), 3(b), and 3(d)–3(g)).
