Antigen
An antibody is a glycoprotein that is produced by plasma cells. It consists of heavy chains and light chains. An antigen is a molecule that interacts with an antibody (or T-Cell). When the antigen interaction induces an immune response it is known as an immunogen.
a toxin or other foreign substance that induces an immune response in the body, especially the production of antibodies.

In economics, a price system determines the allocation of scarce resources and induces supply to respond to change in demand. It also rations out scarce product, indicates change in want, is in use in the production of goods and services, and determines the reward factors of production.

Antigens are substances that provoke an immune response (they're the ultimate target for the immune system). Antibodies are simply proteins that are secreted as a result of the antigen provoked immune response. In short, antigens cause the disease and antibodies cure it.
Erythropoietin, a hormone secreted by the kidney, stimulates the production of red blood cells. Almost all of the erythropoietin within the circulation is derived from the kidneys. Hypoxia is one of the main stimuli that induces erythropoietin secretion from the kidneys. In severe kidney disease, a decrease in erythropoietin production results in severe anemia.
Estrogen induces a biphasic feedback on the gonadotropin releasing. In the first phase (it is discussed whether the phases are separated by time or by estrogen levels) it induces an negative feedback on both FSH and LH. The inhibition of FSH is more evident in this case. In the second phase the feedback is positive. In contrary the positive feedback is much more evident in the LH level.
UVB exposure induces the production of vitamin D in the skin. The majority of positive health effects relate to this vitamin which has regulatory roles in calcium metabolism (which is vital for normal functioning of the nervous system, as well as for bone growth and maintenance of bone density) immunity, cell proliferation, and blood pressure.
