Janeway immunology

Janeway immunology refers to the understanding of how our body's immune system detects and responds to threats. It emphasizes the role of "pattern recognition receptors" (PRRs) on immune cells, which identify common features of pathogens like bacteria and viruses. When PRRs recognize these patterns, they activate immune responses to eliminate the invaders. Janeway highlighted that the innate immune system uses these receptors as a first line of defense, setting the stage for activation of the more specific adaptive immune system. This framework helps explain how our body quickly identifies and responds to infections.
