IFNG and cranioectodermal dysplasia: Therefore, dataset GSE123649 was investigated again and found that the expression of IFN-γ in γδT cells was higher in the PGC group compared with the GFD counterpart (Fig. 8B), while no significant difference was observed between gluten-free-diet patients and healthy controls (Fig. 8B), intimating that the upregulation of the response to IFN-γ in CeD patients partly resulted from γδT cells.
