Janeway theory

Janeway's Theory of Immunity explains how the body's immune system recognizes and responds to pathogens like bacteria and viruses. It emphasizes the role of specialized immune cells (like dendritic cells and T-cells) that detect foreign invaders and coordinate a defense. The theory highlights that the immune system doesn't just respond randomly; it has a sophisticated way of "learning" and "remembering" pathogens, enabling quicker and stronger responses upon re-exposure. Essentially, Janeway's theory helps us understand the complex interactions and signaling involved in immune surveillance and activation, contributing to how our body defends against disease.
