The Frequency of Intrathyroidal Follicular Helper T Cells Varies with the Progression of Graves’ Disease and Hashimoto’s Thyroiditis

Figure 4

Correlations between Tfh cells and autoantibodies or thyroid function in HT patients. (a) Correlation between the frequency of circulating CD4⁺CXCR5⁺PD-1⁺ Tfh cells and the levels of autoantibodies in HT patients. (b) Correlation between the frequency of intrathyroidal CD4⁺CXCR5⁺ICOS^high Tfh cells and the levels of autoantibodies in HT patients. (c) Correlation between the frequency of intrathyroidal CD4⁺CXCR5⁺ICOS^-high Tfh cells and the levels of FT3, FT4, and TSH in HT patients.
