Antigen-antibody response

The antigen-antibody response is a key part of the immune system’s defense. When the body detects a foreign substance (antigen) like a virus or bacteria, it produces special proteins called antibodies. These antibodies bind to the antigens, marking them for destruction or neutralization. This process helps identify and remove harmful invaders, preventing illness. The immune response can remember these invaders, allowing the body to respond quicker if exposed again. Overall, this interaction is crucial for protecting the body from infections and maintaining health.
