Answer:
Superantigens produce intense immune responses by stimulating lymphocytes to produce cytokines.
Explanation:
Superantigens are a group of bifunctional proteins that interact with at least two receptors expressed on different cells. The superantigen´s receptors in lymphocyte T is located in the same place where the lymphocyte interacts with a conventional antigen, RCT. The capability of these superantigens to join their receptors in many T cells, shoots a series of processes that conduce to cellular activation, differentiation, proliferation, and great production and release of cytokine.
Superantigens constitute the most potent natural immunostimulators known.
The correct answer is option 1, that is, there is an evolutionary link between the classes.
