2009 SEP 16 ... These inhibitors also hinder cysteine release and consequently prevent reduction of the extracellular medium: addition of exogenous reducing agents restores IL-1 beta secretion. Not only ... IL-1 beta secretion. Not only silencing of thioredoxin, but also of the ROS scavenger superoxidedismutase 1 results in inhibition of IL-1 beta secretion. Thus, PAMP-induced ROS trigger ...
