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

Figure 6

Representative images of TLR9 expression in NH, PTC, and ATC. TLR9 staining was absent in NH. Moderate cytoplasmic expression was observed 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 TLR9 in NH. (c) HE of PTC. (d) Moderate intensity of IHC for TLR9 in PTC. (e) HE of ATC. (f) Moderate intensity of IHC for TLR9 in ATC. (g) TLR9 IHC scores in NH, PTC, and ATC. The IHC scores were significantly upregulated in PTC and ATC compared to NH (). .
