All Antigens Are Proteins. Antibodies specifically recognize and bind to their corresponding antigens, neutralizing them or marking them for destruction by immune cells. antigens are usually proteins or sugars (polysaccharides) found on the outside of things like cells or viruses. the most potent and commonly encountered antigens are proteins followed by polysaccharides. any foreign material—usually of a complex nature and often a protein—that binds specifically to a receptor molecule. while antigens are foreign substances that induce an immune response, antibodies are proteins produced by the immune system in response to these antigens. However, other molecules like lipids and nucleic acids can also act as antigens when complex with proteins and polysaccharides. In general, two main divisions of antigens are recognized: human leukocyte antigen (hla) is present on the surface of all human cells that have a nucleus. It identifies the cells as self. hla also functions to signal the immune system that the cell is diseased by displaying peptides (parts of proteins) from inside the cell.
