An immunohistochemical analysis of the TLR-4 protein expression in pancreatic carcinoma, cholangiocarcinoma, and their adjacent normal tissues: Expression of the TLR-4 protein in pancreatic carcinoma tissues (×100) (a); expression of the TLR-4 protein in paracarcinoma normal tissues (×100) (B); expression of the TLR-4 protein in cholangiocarcinoma tissues (×100) (c); expression of the TLR-4 protein in para-carcinoma normal tissues (×100) (d)
TLR-4: toll-like receptor
