MTC group had a profile of individuals with high production of the molecules CXCL-9, IL-6, and IL-10, whereas the STC group presented a profile of high producers of the molecules CXCL-8, CXCL-9, CCL-2, CXCL-10, IL-6, IL-1β, IL-10, and IL-2, an inverse profile to that observed in the HD group (Figure 4A). This evidence concerns the gene IL6 and medullary thyroid gland carcinoma.
