Overview
Toll-like receptors (TLRs) are a type of protein found on cell surfaces that form part of the immune system. When certain pathogens, such as bacteria, viruses, and parasites, enter the body, TLRs recognize their presence and send signals to activate immune cells, such as macrophages and dendritic cells. This is known as Toll-like receptor signaling. This signaling process helps to protect the body against these pathogens, allowing the immune system to respond quickly and effectively. TLRs play an important role in the fight against infectious diseases, and their function is being studied to inform future treatments and therapies. Additionally, researchers are exploring how TLRs can be used to develop therapies for cancer and other diseases.
