The substance that the body regards as foreign, which includes viruses, bacteria, toxins, and transplanted organs, is called an "antigen." Antigens trigger an immune response, as the immune system identifies them as potentially harmful invaders. This response can lead to the production of antibodies and activation of immune cells to eliminate the threat.

Antigen is the medical term meaning foreign substance.
When antibodies bind to the epitopes of an antigen(bacteria) via antigen receptors, the antibodies present the bacteria to a macrophages in a form that they recognize the foreign substance and engulf them. This antibody-antigen "team work" is also known as opsonization
A pathogen is a foreign body, bacteria, or virus.
A heterologous protein; however, any abnormal substance (bacteria, viruses, cancer cells) in the body is called an antigen
It is called organ rejection, which occurs when the recipient's immune system recognizes the transplanted organ as foreign and tries to attack and destroy it. Organ rejection can lead to the failure of the transplanted organ if not managed properly with immunosuppressive medications.
