Superantigens increase the survival of mice bearing T cell lymphomas by inducing apoptosis of neoplastic cells. [PDF]
PLoS ONE, 2010 Superantigens bind to major histocompatibility complex class II molecules and interact with T cells expressing a particular T cell receptor Vβ inducing a strong proliferation/deletion response of the superantigen-reactive T cells.

Proinflammatory synergy between protease and superantigen streptococcal pyogenic exotoxins [PDF]
Infection and ImmunityStreptococcal pyogenic exotoxins (Spe proteins) secreted by Streptococcus pyogenes (group A Streptococcus, GAS) are responsible for scarlet fever and streptococcal toxic shock syndrome.

Staphylococcus Aureus Toxins and Asthma: Pathophysiological Mechanisms, Clinical Relevance, and Therapeutic Implications in the Biologics Era [PDF]
ToxinsStaphylococcus aureus frequently colonizes the skin and upper airways and produces a broad repertoire of immunomodulatory molecules. In asthma, the most consistent evidence concerns staphylococcal enterotoxins (SEs), which can act both as superantigens ...

Superantigen Recognition and Interactions: Functions, Mechanisms and Applications
Frontiers in Immunology, 2021 Superantigens are unconventional antigens which recognise immune receptors outside their usual recognition sites e.g. complementary determining regions (CDRs), to elicit a response within the target cell.

Experimental Dermatology, 1996 Abstract Superantigens are potent modulators of the immune system. Some of their biological and immunological properties are reviewed here with special attention to their potential significance for cutaneous inflammation, specific skin immune responses and skin diseases.

Peptidoglycan Contribution to the B Cell Superantigen Activity of Staphylococcal Protein A
mBio, 2021 Staphylococcus aureus causes reiterative and chronic persistent infections. This can be explained by the formidable ability of this pathogen to escape immune surveillance mechanisms. Cells of S. aureus display the abundant staphylococcal protein A (SpA).

Streptococcal superantigens and the return of scarlet fever.
PLoS Pathogens, 2021 Streptococcus pyogenes (group A Streptococcus) is a globally disseminated and human-adapted bacterial pathogen that causes a wide range of infections, including scarlet fever. Scarlet fever is a toxin-mediated disease characterized by the formation of an

Novel Tissue Level Effects of the Staphylococcus aureus Enterotoxin Gene Cluster Are Essential for Infective Endocarditis. [PDF]
PLoS ONE, 2016 Superantigens are indispensable virulence factors for Staphylococcus aureus in disease causation. Superantigens stimulate massive immune cell activation, leading to toxic shock syndrome (TSS) and contributing to other illnesses.
