What is the Origin of Immunogenicity?

The term Immunogenicity is derived from the field of immunology, with 'immuno' referring to the immune system and 'genicity' denoting the capacity to generate or produce something. Its origin is tied to the development of vaccines and protein-based therapeutics, where the potential for an immune reaction is a primary consideration in drug design. In the context of hormonal health, it helps explain why bioidentical hormones, being structurally identical, generally exhibit lower immunogenicity than synthetic analogs.

What is the Mechanism of Immunogenicity?

The mechanism of immunogenicity begins with the presentation of the foreign substance's molecular fragments to T-lymphocytes by antigen-presenting cells. If the substance is sufficiently different from endogenous molecules, the T-cells initiate a cascade that results in the activation of B-lymphocytes. These B-cells then differentiate into plasma cells that secrete specific antibodies designed to bind and neutralize the foreign compound. The resulting antibody-antigen complexes are then cleared from the circulation, potentially reducing the therapeutic agent's effective concentration and biological action.

Immunogenicity

Meaning

Immunogenicity is the capacity of a substance, such as a drug, hormone, or foreign molecule, to provoke an immune response in the body. In clinical endocrinology and hormone therapy, this term is specifically used to describe the potential for an administered compound to be recognized as foreign, leading to the production of antibodies against it. High immunogenicity in a therapeutic agent, like a peptide or protein hormone, can reduce its efficacy by neutralizing its action or, in rare cases, trigger adverse immunological reactions.
