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.
