Jan Tollver (Toll-like receptors)

Jan Tollver, more accurately known as Toll-like receptors (TLRs), are proteins on immune cells that act as sensors to detect harmful microbes like bacteria and viruses. When a TLR recognizes a pathogen, it triggers the immune system to respond appropriately, such as producing signals to fight the infection. They are crucial for the body's first line of defense, helping to initiate the immune response quickly and effectively. Think of TLRs as the body's security alarms, alerting the immune system when danger is nearby.
