Staphylococcal enterotoxin A induces small clusters of HLA-DR1 on B cells. [PDF]
PLoS ONE, 2009 The superantigen SEA causes non-specific hyperactivation of T and B cells at low concentrations. Studies of mutants or soluble proteins suggest SEA is bivalent for its ligand, MHC class II. However, the interaction between these molecules on intact cells

Optimizing Two-Color Semiconductor Nanocrystal Immunoassays in Single Well Microtiter Plate Formats
Sensors, 2011 The simultaneous detection of two analytes, chicken IgY (IgG) and Staphylococcal enterotoxin B (SEB), in the single well of a 96-well plate is demonstrated using luminescent semiconductor quantum dot nanocrystal (NC) tracers.

Chemotactic Activity Generated by Staphylococcal Enterotoxin B [PDF]
Infection and Immunity, 1971 Staphylococcal enterotoxin B (SEB) has significant toxicity for several mammalian species by both oral and parenteral routes. When highly purified SEB was incubated for 1 hr at 37 C with fresh serum from normal young adult men with little or no antibody activity for SEB, a factor(s) chemotactic for human polymorphonuclear leukocytes (PMN) was formed ...

A DNA Spiegelmer to staphylococcal enterotoxin B [PDF]
Nucleic Acids Research, 2003 Bacterial staphylococcal enterotoxin B is involved in several severe disease patterns and it was therefore used as a target for the generation of biologically stable mirror-image oligonucleotide ligands, so called Spiegelmers. The toxin is a 28 kDa protein consisting of 239 amino acids.

Superantigens Modulate Bacterial Density during Staphylococcus aureus Nasal Colonization
Toxins, 2015 Superantigens (SAgs) are potent microbial toxins that function to activate large numbers of T cells in a T cell receptor (TCR) Vβ-specific manner, resulting in excessive immune system activation.

Identifying Cytokine Motif‐Containing, Immunomodulatory Bacterial Proteins in Human Gut Microbiome
Advanced Science, EarlyView.By building and constructing HMM (Upper left, blue), the authors identify CMCPs in bacteria genomes and CRC related metagenomes and enriched CRC‐related CMCPs (Upper right, blue). They analyze sequence and structural similarity of hits (Lower left, green), test function with engineered EcN delivered to tumors in a mouse tumor model (Lower right, pink ...
