Fan fiction, also called fanfiction, is derivative fiction written using another author's characters and universe. Fanfiction authors write stories about their favorite characters from books, movies, or comics.
Antibodies, also called immunoglobulins, are proteins manufactured by the body that help fight against foreign substances called antigens. When an antigen enters the body, it stimulates the immune system to produce antibodies. (The immune system is the body's natural defense system.) The antibodies attach, or bind, themselves to the antigen and inactivate it. Every healthy adult's body has small amounts of thousands of different antibodies.
Allergies happen when the bodyâs immune system responds to a substance that is foreign for instance pet dander, pollen or dust mites. The immune system triggers proteins referred to as antibodies. These antibodies protect the body from foreign invaders that would make the individual sick or create an infection.
