Abstract:
Twenty-five percent of the population are permanent carriers of Staphylococcus aureus, possibly producing a variety of toxins with superantigenic properties. Staphylococcal superantigens are a group of high- molecular-weight pyrogenic proteins that have in common an extremely potent stimulatory activity for T-lymphocytes, macrophages, mast cells, eosinophils, and epithelial cells. The role of staphylococcal superantigens in atopic dermatitis has recently been recognized, and new evidence suggests that similar mechanisms may also be relevant in airway disease. This circumstantial evidence is currently limited to rhinitis, sinusitis, and possibly asthma, but may, if supported, open a new understanding of pathomechanisms and therapeutic targets.

Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...
