Figure 3

Representative images of TLR4 expression in NH, PTC, and ATC. No expression was detected, except for mononuclear cells present in the stroma. 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 TLR4 in NH. (c) HE of PTC. (d) No expression of IHC for TLR4 in PTC. (e) HE of ATC. (f) No expression of IHC for TLR4 in ATC.
