An injection of a small dose (1 to 50,g) of synthetic polyriboinosinic acid complexed with polyribocytidylic acid (poly I:poly C) inhibited the induction of tryptophan oxygenase by cortisone acetate; it induced tyrosine amino transferase, and it accelerated the loss of liver glycogen reserves. It also resulted in first a suppression followed by an activation of the reticuloendothelial system as...
Endotoxin tolerance (ET) is a state of reduced responsiveness to endotoxin stimulation after a primary bacterial insult. This phenomenon has been described in several pathologies, including sepsis, in which an endotoxin challenge results in reduced cytokine production. In this study, we show that the NFκ L chain enhancer of activated B cells 2 (NFκB2)/p100 was overexpressed and accumulated in a...
An injection of a small dose (1 to 50 mug) of synthetic polyriboinosinic acid complexed with polyribocytidylic acid (poly I:poly C) inhibited the induction of tryptophan oxygenase by cortisone acetate; it induced tyrosine amino transferase, and it accelerated the loss of liver glycogen reserves. It also resulted in first a suppression followed by an activation of the reticuloendothelial system ...
Our group and others have shown in vitro that repeated exposure of human mononuclear cells (MNC) to lipopolysaccharide can induce endotoxin tolerance, evidenced by downregulation of TLR2 and TLR4 mRNA and surface protein; moreover, the ability of the MNC to secrete inflammatory cytokines is reduced. In situ studies performed on diseased and healthy gingiva suggest that a similar pattern of endo...
Background and purpose: Access to safe drinking water is of the utmost importance in public health around the world. Presence of contaminants, such as secondary bacterial growth and endotoxins could reduce the quality of water resources. This study aimed at investigating the occurrence, seasonal variation, and removal of endotoxins in a conventional water treatment plant (WTP) in Tehran, Iran. ...
