Neutrophil--CD4+CD25+ T regulatory cell interactions: a possible new mechanism of infectious tolerance.

abstract：:Several papers have demonstrated the importance of substances from natural sources which can exert powerful anti-inflammatory effects. In this respect, hydroxytyrosol, one of the major elements of the phenolic components of olive oil, has been extensively studied for its anti-inflammatory activities and safety profile...
