IL17A and autoimmune polyendocrinopathy: An analysis of the correlations between cytokines and laboratory data in APS patients (Supplementary Tables 4, 5) showed that IL-2 (r = −0.420, p=0.010), IL-4 (r = −0.392, p=0.016), IL-10 (r = −0.331, p=-0.046), IL-17 (r = −0.479, p=0.006), and IFN-γ (r = −0.339, p=0.040) correlated negatively with the titres of the aPL aCL (Figure 3).
