Target Antigen

Molecular classification: Other (Catchall term for "antigen," not a specific protein/receptor)

Overview

The term target antigen refers to any molecule or molecular structure that is recognized and bound by an antibody, T cell receptor, or other immune system component, thereby triggering an immune response. Antigens are not limited to proteins—they may also be peptides, polysaccharides, lipids, or nucleic acids. In the context of therapeutic development, "target antigen" signifies the molecule selected as the focus for antibody generation or immune targeting. Because the term is generic, it is not specific to any one molecule, receptor, or gene product, but rather functions as a category label for a wide variety of possible immune targets, such as those found on pathogens, tumor cells, or in autoimmune disease states.

Other names: antigenimmunogentarget moleculetarget epitope

Mechanism of action

Antibody binding to antigen (basis of many therapeutics/diagnostics); Vaccination/immunization against antigen; Antibody-drug conjugate (ADC) delivery

Biological functions

Elicitation of immune responseImmune recognitionSignaling for adaptive immunity

Disease associations

Cancer (e.g., tumor-associated antigens)Infection (viral, bacterial, parasitic)Autoimmune disease (autoantigens)Other (any pathology involving immune response to specific molecules)

Safety considerations

Off-target effects if the antigen is not sufficiently specific to disease tissueAutoimmunity if self-antigens are targetedCross-reactivity with normal tissues
