Janeway's immune system model

Janeway’s immune system model proposes that our innate immune response is constantly scanning for signs of danger, such as pathogens or damaged cells. Key immune cells act like sensors that detect specific molecular patterns common to microbes. When these sensors recognize threats, they activate the immune system's defense mechanisms promptly. This model highlights the innate immune system’s role as the first responder, working in concert with the adaptive immune system to identify and fight off invaders efficiently. It underscores the importance of pattern recognition in initiating rapid immune responses essential for protection.
