Previous reports describe that the increased serum levels of some cytokines (such as IL-4, IL-10, IL-1α, IL-1β, IL-8 and IL-21) seen in CeD patients are correlated with IgA anti-TG2 titers and villous atrophy, making them candidates for diagnostic biomarkers [53,54]. Here, CXCL8 is linked to cranioectodermal dysplasia.
