Effects of staphylococcal enterotoxins on human neutrophil functions and apoptosis.
Staphylococcal enterotoxins have marked effects on the properties of T cells and monocytes and have recently been reported to affect neutrophil function. In this study, we investigated the abilities of staphylococcal enterotoxins A and B and toxic shock syndrome toxin 1 to affect respiratory burst activity and to delay apoptosis in human neutrophils. When cultures containing approximately 97% n...

In this study the programmed cell death (apoptosis) of human neutrophilic granulocytes was investigated in the presence and absence of fetal calf serum (FCS), cycloheximide and actinomycin-D. The results show that when FCS is omitted from cultures, apart from a decrease in viability, the percentage of apoptotic cells and DNA fragmentation increases. Apoptosis is accelerated in serum withdra...
