The correct answer is antigens and epitope.
An antigen is a substance which triggers an immune response in an organism. This can be either a foreign substance, such as a pathogen, or a specific part of the host organism (in this case this is an autoimmune response). The presence of an antigen activates a specific part of the immune system, called antibody. Each antigen has a specific antibody, which is tailored by the immune system accordingly. More specifically, the antibody has a specific structure, called paratope, which is complementary and binds like a key to a specific structure of the antigen, called epitope.

Microorganisms that live in severe habitats, such as very
hot, acidic, or salty environments are called extremophiles, which are
bacteria, archaea and eukaryotes. They are the most successful organisms
because they can adapt in any environment. They can live in oceans, rivers,
soil, and even inside a human’s body.
