Staphylococcal enterotoxins (SEs) are powerful superantigens that stimulate non-specific T-cell proliferation produced by Staphylococcus aureus and draw considerable attention as ideal drugs for cancer therapy. The filtrate of S. aureus culture has been used as ampul named Staphylococcal enterotoxin C injection in clinic for 10 years in China and proved to be effective. The superantigen SEC cla...

It was believed that food poisoning in Osaka in 2000 was due to small amounts of staphylococcal enterotoxin A (SEA) in reconstituted milk. Results of this study clearly indicate that SEH was also present in the raw material of reconstituted milk, indicating that the food poisoning was caused by multiple staphylococcal enterotoxins.

There is currently no clear in vitro model to study the Th2 status atopic dermatitis (AD). Staphylococcus aureus, skin-homing cutaneous lymphocyte-associated antigen (CLA)+ memory T cells and IL-13 are key players AD. Circulating CLA+ reflect abnormalities We have studied CLA+/- T-cell response staphylococcal enterotoxin B (SEB) when cocultured with autologous lesional epidermal from adult non-...

BACKGROUND Accurate and rapid diagnosis of bacterial arthritis is not always possible in unvaccinated (Streptococcus pneumoniae and Haemophilus influenzae type B) children in Iran. OBJECTIVES Searching the staphylococcal superantigen (entrotoxin A, B, C and TSST1) in synovial fluid of cases with inflammatory arthritis. PATIENTS AND METHODS This cross sectional study was implemented in the p...

The superantigenic staphylococcal enterotoxins are important virulence factors and contribute to various diseases, including food poisoning and toxic shock. Dexamethasone, an anti-inflammatory agent, attenuated staphylococcal enterotoxin B (SEB)-induced hypothermia and serum proinflammatory cytokines and improved survival from 0% to 86% in a lethal mouse model of SEB-mediated shock.

Background and Objectives: Staphylococcal enterotoxin D as a supper antigen is produced by infected samples of human and animal sources. The aim of this study was to standardize the detection methods for the Staphylococcus strain producing enterotoxin D. Materials and Methods: A PCR method was set up for detection of enterotoxin D gene (ent D) in Staphylococcus aureus samplesisolated from the h...

To determine the levels of maturation and differentiation of murine CD4 single-positive (SP) T cells, we compared the secondary responses of staphylococcal enterotoxin A (SEA)-induced neonatal thymic, adult thymic and adult splenic CD4 SP T cell blasts prepared from whole or heat-stable antigen(low) CD4 SP T cells. Proliferative responses upon re-stimulation with SEA were strong in adult spleni...

BACKGROUND Camelids and sharks possess a unique subclass of antibodies comprised of only heavy chains. The antigen binding fragments of these unique antibodies can be cloned and expressed as single domain antibodies (sdAbs). The ability of these small antigen-binding molecules to refold after heating to achieve their original structure, as well as their diminutive size, makes them attractive ca...
