pubmed:abstractText |
Lipopolysaccharide (LPS) and ratio-detoxified LPS (Rd-LPS) from Salmonella typhimurium were analysed for their ability to stimulate murine peritoneal exudate cells (PEC) and macrophages. Rd-LPS induced much more inflammatory response as compared to LPS. PEC numbers/mouse obtained were significantly higher (3-fold) in response to Rd-LPS than LPS. The haemorrhage was induced in mice by LPS but not by Rd-LPS. Activation of macrophages in vivo by Rd-LPS was significantly higher as compared to LPS. This was evident from the increase levels of their lysosomal enzymes and cytokines. Rd-LPS induced 10-fold increase in acid phosphatase contents of macrophages as compared to controls while only 7-fold increase was obtained with LPS. Arylsulfatase and beta-glucuronidase increased by about 2-fold by Rd-LPS and LPS. Macrophages incubated with Rd-LPS in vitro showed 16-fold and 20-fold increase in the cell associated levels of arylsulfatase and beta-glucuronidase respectively as compared to unstimulated cells. On the other hand, only 6-fold increase was observed in response to LPS in the levels of both the enzymes. TNF-[symbol: see text] and IL-1 secreted by macrophages increased considerably in response to Rd-LPS as compared to those released by LPS. Rd-LPS, thus seems to be a better immunomodulator than untreated LPS.
