Toll-like receptors (TLRs) are the most essential pattern recognition receptors in mediating the effects of innate immunity. It plays a pivotal role in inducing immune response against a number of pathogens, various diseases conditions including pathogenesis of cancer. Inflammation is often associated with the development and progression of most of cancer, where TLRs interplay very crucial roles. Moreover, TLRs activation can impact the initiation, progression and treatment of cancer by modulating the inflammatory microenvironment. Rapidly growing number of evidences related to TLRs function and expression in cancer cells, suggests its critical association with chemoresistance and tumourigenesis. The current chapter describes the development of various agonist and antagosist for TLRs and their application in cancer therapeutics. The aim of this book chapter is to highlights basic features of TLRs, and its role in cancer progression. It also addresses, how a defect in the TLRs signaling pathway can contributes towards carcinogenesis and recent development of cancer therapeutics that target TLR signaling pathways.
