From: Toll-like receptor 2 is present in the microenvironment of oral squamous cell carcinoma
Photomicrographs of OSCC isotype control (A) and irritative hyperplasia (B) demonstrating no TLR 2 expression in the epithelium or on inflammatory cells in the connective tissue. The invading epithelial islands of an OSCC demonstrate weakly (C) and strongly (D) positive-TLR 2 expression. Some inflammatory cells in the adjacent fibrous connective tissue show strong positivity in both (C) and (D).
