Toll-like Receptors

Toll-like receptors (TLRs) are critical components of the immune system. They are a type of protein found on the surface of cells that detect and respond to foreign substances, such as bacteria and viruses. Activation of a TLR sets off a cascade of events that lead to an immune response, such as inflammation and increased production of antimicrobial agents that help fight infection. TLRs also play an important role in promoting tissue healing and repair. Studies have shown that alterations in TLR signaling can be associated with various diseases, including chronic inflammation and autoimmunity. Therefore, TLR research has significant implications for the development of novel treatments for many different diseases.
