What is a immunity protein?

Immunity proteins, often referred to as immune proteins, are molecules produced by the immune system to help defend the body against pathogens such as bacteria, viruses, and other foreign invaders. These proteins include antibodies, which specifically recognize and neutralize antigens, as well as cytokines and complement proteins that play roles in signaling and enhancing immune responses. They are crucial for maintaining the body's defense mechanisms and ensuring a swift response to infections.
