In Japanese pop culture, an idol (ã¢ã¤ãã«, aidoru, a Japanese rendering of the English word idol) is an entertainment personality marketed as someone to be admired, usually for their cuteness or coolness. Idols are intended to be role models.hether a person is categorized as an idol depends on how he or she got into the entertainment business and whether he or she is promoted as being an idol. Some entertainment (mostly music production) companies and music projects specialize in idols, and they automatically market everyone they sign as an idol.
Medical Definition of immunology. plural. immunologies. : a science that deals with the immune system and the cell-mediated and humoral aspects of immunity and immune responses.
In immunology, an antigen is a molecule capable of inducing an immune response (to produce an antibody) in the host organism. Sometimes antigens are part of the host itself in an autoimmune disease. Antigens are targeted by antibodies. Each antibody (immune response) is specifically produced by the immune system to match an antigen after cells in the immune system come into contact with it; this allows a precise identification/matching of the antigen and the initiation of a tailored response.
