IMMUNOLOGY

Detailed explanation-1: -When an antigen binds to a receptor molecule, it may or may not evoke an immune response. Antigens that induce such a response are called immunogens. Thus, it can be said that all immunogens are antigens, but not all antigens are immunogens.

Detailed explanation-2: -Antigens are markers that tell your body that something is foreign. Your immune cells make antibodies to recognize and destroy harmful antigens. In fact, you can think of antigens as antibody generators.

Detailed explanation-3: -Similarities Between Antigen and Immunogen Antigen and immunogen are two types of molecules that bind to the components of the immune system, including antibodies, B cells, and T cells. Moreover, they can be either proteins, polysaccharides, lipids or nucleic acids.
