Various antigens and autoantigens

The term Various antigens and autoantigens refers to a broad and non-specific category of molecular targets rather than a single defined protein or receptor. In a pharmacological context, this designation is most frequently associated with polyclonal antibody therapies, such as Intravenous Immunoglobulin (IVIG), which contain a diverse repertoire of antibodies directed against a wide array of exogenous pathogens (antigens) and endogenous self-proteins (autoantigens). These therapies function by neutralizing toxins, inhibiting viral entry, and modulating the immune system through interactions with Fc receptors and the complement system. Because this category encompasses thousands of potential binding sites, it is typically used in clinical databases to describe the multi-target nature of blood-derived products or broad-spectrum immunotherapies. While critical for treating primary immunodeficiencies and autoimmune disorders like Kawasaki disease or Chronic Inflammatory Demyelinating Polyneuropathy (CIDP), the lack of specificity makes it an unconventional entry for targeted drug design.
