The term "immunoproteome" refers to all the proteins in an organism that can elicit an immune response. Synonyms for immunoproteome include "immunogenic proteome", "antigenic proteome", and "immune-reactive proteome". These terms all describe the same concept of the collection of proteins that can stimulate an immune response within an organism. The study of the immunoproteome is essential in understanding the interactions between host and pathogen, and developing vaccines and other immunotherapies. By identifying the specific immunogenic proteins, researchers can develop targeted interventions to treat and prevent diseases. The synonymic terms for immunoproteome all help describe the same critical aspect of immunology research.
