ブドウ球菌エンテロトキシンB Staphylococcus aureus由来

Staphylococcal Enterotoxin B (SEB) is a potent exotoxin produced by Staphylococcus aureus, classified as a superantigen due to its unique ability to activate T-cells non-specifically. This activation occurs through the cross-linking of T-cell receptors (TCRs) and major histocompatibility complex (MHC) class II molecules, leading to a massive release of cytokines and an exaggerated immune response. SEB is associated with food poisoning and toxic shock syndrome, making it a critical agent for studying the mechanisms of bacterial pathogenesis and immune dysregulation.
In addition to its role in infectious disease research, SEB serves as a valuable tool for investigating autoimmune conditions and the development of immunotherapies. Its ability to induce T-cell activation and proliferation makes it an important reagent for exploring T-cell biology, including differentiation, memory formation, and the effects of various immunomodulators.
