Janeway model of innate immunity

The Janeway model of innate immunity describes how our body's initial defense system recognizes common features of pathogens (like bacteria and viruses) rather than specific invaders. These features, called pathogen-associated molecular patterns (PAMPs), are detected by special receptors on our immune cells. When these receptors identify PAMPs, they trigger rapid responses to fight the infection. This model highlights the importance of pattern recognition in early immune defense, providing a quick, generalized response to a wide range of pathogens before the more targeted, adaptive immune system is activated.
