About TLRs

Toll-like Receptors (TLRs) function in human immune cells as the sensors of pathogens. They recognize different microbial products present in pathogens such as bacteria, viruses and parasites, and mount an appropriate immune response against the foreign invaders. TLRs have also been shown to recognize endogenous ligands in autoimmune diseases. TLRs have become attractive targets for developing immune modulators to treat a variety of diseases.

Idera Pharmaceuticals is a drug discovery and development company that is developing drug candidates to treat infectious diseases, autoimmune diseases, cancer, and respiratory diseases, and for use as vaccine adjuvants. The Company’s proprietary drug candidates are designed to modulate specific TLRs, which are a family of immune system receptors present in immune system cells that direct the immune system to respond to potential disease threats. The Company’s pioneering DNA chemistry expertise enables us to identify drug candidates for internal development and creates opportunities for multiple collaborative alliances. The Company’s lead TLR9 agonist, IMO-2125, is currently in a Phase 1 trial for the treatment of hepatitis C virus infection. The Company has also created novel DNA-based compounds that have been shown to act as antagonists to TLRs 7 and 9 in preclinical studies.
