Immunohistochemical Analysis of Toll-Like Receptors, MyD88, and TRIF in Human Papillary Thyroid Carcinoma and Anaplastic Thyroid Carcinoma

Figure 5

Representative images of TLR7 expression in NH, PTC, and ATC. TLR7 expression was virtually undetectable in NH and weak in PTC and ATC. HE: hematoxylin and eosin staining; IHC: immunohistochemistry; NH: nodular hyperplasia; PTC: papillary thyroid carcinoma; ATC: anaplastic thyroid carcinoma. Scale bar: 50 μm. (a) HE of NH. (b) No expression of IHC for TLR7 in NH. (c) HE of PTC. (d) Quit weak intensity of IHC for TLR7 in PTC. (e) HE of ATC. (f) Quit weak intensity of IHC for TLR7 in ATC. (g) TLR7 IHC scores in NH, PTC, and ATC. The IHC score was significantly upregulated in ATC compared to NH (). .
