The Staphylococcal Toxins γ-Hemolysin AB and CB Differentially Target Phagocytes by Employing Specific Chemokine Receptors

The role of chemokines and chemokine receptors in mycosis fungoides

Background: Chemokines are a family of cytokines initially characterized by their capacity to induce chemotaxis, or directed leukocyte migrations. These receptors are activated by chemotactic cytokines called chemokines. Interactions between chemokines and chemokine receptors also are involved in tumorigenesis, migration and invasion of lymphoma cells.Methods: An English literature search...

Molecular basis of transmembrane beta-barrel formation of staphylococcal pore-forming toxins.

Pathogenic bacteria secrete pore-forming toxins (PFTs) to attack target cells. PFTs are expressed as water-soluble monomeric proteins, which oligomerize into nonlytic prepore intermediates on the target cell membrane before forming membrane-spanning pores. Despite a wealth of biochemical data, the lack of high-resolution prepore structural information has hampered understanding of the β-barrel ...

PI3K/Akt/mTOR, a Pathway Less Recognized for Staphylococcal Superantigen-Induced Toxicity

Immunostimulating staphylococcal enterotoxin B (SEB) and related superantigenic toxins cause diseases in humans and laboratory animals by activating cells of the immune system. These toxins bind directly to the major histocompatibility complex (MHC) class II molecules on antigen-presenting cells and specific Vβ regions of T-cell receptors (TCR), resulting in hyperactivation of both T lymph...

Therapeutic Down-Modulators of Staphylococcal Superantigen-Induced Inflammation and Toxic Shock

Staphylococcal enterotoxin B (SEB) and related superantigenic toxins are potent stimulators of the immune system and cause a variety of diseases in humans, ranging from food poisoning to toxic shock. These toxins bind directly to major histocompatibility complex (MHC) class II molecules on antigen-presenting cells and specific Vβ regions of T-cell receptors (TCR), resulting in hyperactivation o...
