Inflammatory responses of bovine polymorphonuclear neutrophils induced by staphylococcal enterotoxin C via stimulation of mononuclear cells.

Stimulation of Mononuclear Cells Staphylococcal Enterotoxin C via by Polymorphonuclear Neutrophils Induced Inflammatory Responses of Bovine

Induction of CC chemokines in human peripheral blood mononuclear cells by staphylococcal exotoxins and its prevention by pentoxifylline.

We investigated the inflammatory processes that might be associated with the arthrogenic activity of Staphylococcus aureus, the principal causative agent of bacterial arthritis. Human peripheral blood mononuclear cells (PBMC) were stimulated with the staphylococcal toxic shock syndrome toxin-1 (TSST-1) or enterotoxin B (SEB) and the production of chemokines was examined. Both TSST-1 and SEB ind...

Comparative Potency of Green Tea and Red Wine Polyphenols in Attenuating Staphylococcal Superantigen-Induced Immune Responses

Proinflammatory cytokines mediate the toxic effects of staphylococcal exotoxins (SE). This study compared the potency of two polyphenols, green tea epigallocatechin gallate (EGCG) and red wine resveratrol (RES), in blocking the pro-inflammatory effects of staphylococcal enterotoxin B (SEB) and toxic shock syndrome 1 (TSST-1). Both EGCG and RES dose-dependently inhibited superantigen-stimulated ...

Changes in some pro-and anti-inflammatory cytokines produced by bovine peripheral blood mononuclear cells following foot and mouth disease vaccination

Interleukin (IL)-17 is exclusively produced by CD4 helper T-cells upon activation. It most often acts as a pro-inflammatory cytokine, which stimulates the release of pro-inflammatory cytokines IL-6, IL-8, TNF-α, and granulocyte-macrophage colony-stimulating factor (GM-CSF). In this study, we studied the in-vitro IL-17 response to specific antigens and a variety of mitogens and compared the IL-1...

Sulfasalazine Attenuates Staphylococcal Enterotoxin B-Induced Immune Responses

Staphylococcal enterotoxin B (SEB) and related exotoxins are important virulence factors produced by Staphylococcus aureus as they cause human diseases such as food poisoning and toxic shock. These toxins bind directly to cells of the immune system resulting in hyperactivation of both T lymphocytes and monocytes/macrophages. The excessive release of proinflammatory cytokines from these cells me...
