Antigen Isotypes

Antigen isotypes are a type of molecule, often proteins, that are expressed on the cell surface of an organism. They carry immunological information about the cell and a host of other functions. Antigen isotypes are a key part in the immune system and are recognized by the body as being foreign or self. Through this recognition, the immune system can react and initiate an immune response, often labeled as either an autoimmune attack or an antigen-specific defense. Antigen isotypes have many applications in medicine, including diagnosis and treatment of diseases, as well as in vaccine development, and are also heavily studied in experimental and research settings.
