Toll-like receptors

Toll-like receptors (TLRs) are proteins found on the surface of certain cells in our immune system. They act like sensors, detecting signs of infection or danger, such as bacteria or viruses. When TLRs recognize these harmful substances, they trigger an immune response, helping the body to fight off infections. Essentially, TLRs play a crucial role in identifying threats and activating the body's defense mechanisms, making them vital for maintaining health and preventing diseases. Their discovery has greatly advanced our understanding of how the immune system functions.
