Host Immune Response

The host immune response is the body's natural defense system that detects and fights off harmful invaders like bacteria, viruses, and other pathogens. When these invaders enter the body, the immune system recognizes specific parts of them as foreign and activates various cells and substances to neutralize or destroy the threat. This process includes inflammation, production of antibodies, and activation of immune cells. The goal is to eliminate the invaders quickly and precisely, while also remembering them for faster responses in future encounters. A well-functioning immune response is essential for overall health and protection against illness.
