“Chelation of extracellular calcium by 2 mM EGTA also blocked the TSST-…-induced sensitization of RTCs to LPS or lipid A. Inhibition of RTC arachidonic acid metabolism by methylprednisolone , indomethacin, ibuprofen, and piriprost significantly inhibited RTC necrosis induced by TSST-1 and LPS or lipid A by 33-62%.”
