Immunolocalization of TLR3 in sinus mucosa and HNECs. Immunostaining of sinus mucosa (A–D), HNEC-ALI cultures (E–H) and HNEC submerged cultures (I–L). TLR 3 specific staining in red (A,E,I), DAPI staining in blue (B,F,J), overlay (C,G) and K in whitefield, negative control staining (D,H) and whitefield in L. TLR immunolocalizes to the epithelial layer (Epi)(A,C). TLR3 specific staining is seen in the nucleus, cytoplasm and cell periphery (arrows in G and I).
