Toll-like receptors (TLRs)

Toll-like receptors (TLRs) are proteins found on the surface of certain immune cells. They act as sensors that recognize specific patterns on pathogens like bacteria and viruses. When TLRs identify these invaders, they activate the immune response, signaling the body to fight off infections. TLRs play a crucial role in the innate immune system, helping the body respond quickly to threats. Essentially, they are like security guards that detect trouble and alert the immune system to take action. This helps protect the body from illness and maintain overall health.
