pathogen recognition

Pathogen recognition is the process by which the immune system identifies harmful microorganisms, like bacteria and viruses, that invade the body. Specialized cells, called immune cells, have receptors that can detect unique markers on these pathogens, such as proteins and sugars. When a pathogen is recognized, these immune cells activate and respond, launching a defense to eliminate the threat. This is a crucial part of our body's ability to protect itself from infections and diseases. Successful pathogen recognition allows for a swift immune response, which is vital for maintaining overall health.
