Endogenous vs Exogenous Antigens. Any molecule or substance that reacts to a product of a specific immune response and stimulates antibody generation is considered as an antigen.The antibody generation by an antigen is called antigenicity of that particular molecule.Antigens can be either a protein or a polysaccharide.he vast majority of antigens are exogenous antigens. They are introduced into the body from outside via various infections agents such as bacteria, viruses, fungi, protozoa, helminthes etc., or environmental substances such as dust mites, foodstuff, pollen etc. by inhalation, ingestion, or injection.
What is an 'Endogenous Variable'. An endogenous variable is a classification of a variable generated by a statistical model that is explained by the relationships between functions within the model. For example, the equilibrium price of a good in a supply and demand model is endogenous because it is set by a producer in response to consumer demand. It is the opposite of an exogenous variable.
