immune system
• decreased antigen specific Ig and IgG1 production are seen following stimulation with bacterial muramyl dipeptide and HSA; however, production is normal when stimulated by HAS plus an artificial TLR7 ligand
• the synergistic effect of bacterial muramyl dipeptide and TLR ligands on the production of IL6 and IL12 is absent in mutant macrophages (J:96035)
• bone marrow derived macrophages produce less IL-6 and TNF when cultured in the presence of L. monocytogenes (J:132126)
• in macrophages pre-treated with TLR ligands (i.e. "tolerized"), macrophages produce significantly less inflammatory cytokines upon incubation with L. monocytogenes than controls that were LPS pre-treated (J:132126)
• bone marrow derived macrophages secrete 73% the amount of IL-6 as wild-type controls due in response to culturing with L. monocytogenes
• a similar relative reduction is observed when macrophages are pre-treated with LPS prior to L. monocytogenes incubation
• bone marrow derived macrophages secrete 77% the amount of TNF as wild-type controls in response to culturing with L. monocytogenes
• TNF secretion is 57% that of controls when macrophages are pre-treated with LPS prior to L. monocytogenes incubation
• homozygotes are resistant to endotoxin shock produced by LPS following bacterial muramyl dipeptide priming but not to endotoxin shock produced by LPS alone
• homozygotes are more susceptible to Listeria monocytogenes infection via intragastric exposure but not via intraperitoneal or intravenous exposure
• however, no signs of intestinal inflammation and no difference in susceptibility to dextran sulfate induced colitis are seen

• in macrophages pre-treated with TLR ligands (i.e. "tolerized"), macrophages produce significantly less inflammatory cytokines upon incubation with L. monocytogenes than controls that were LPS pre-treated
• bone marrow derived macrophages secrete 40% the amount of IL-6 as wild-type controls due in response to culturing with L. monocytogenes
• IL-6 secretion is 7% that of controls when macrophages are pre-treated with LPS prior to L. monocytogenes incubation
• IL-6 secretion is 18% that of controls when macrophages are pre-treated with E. Coli prior to L. monocytogenes incubation
• bone marrow derived macrophages secrete 56% the amount of TNF as wild-type controls in response to culturing with L. monocytogenes
• TNF secretion is 13% that of controls when macrophages are pre-treated with LPS prior to L. monocytogenes incubation
• TNF secretion is 26% that of controls when macrophages are pre-treated with E. Coli prior to L. monocytogenes incubation
• there is an approximately 5-fold higher number of bacterial colony-forming units in the liver and spleen than in wild-type mice 2 days after infection with L. monocytogenes
• when mice are pre-treated with LPS before infection, bacterial load in the liver and spleen is about 50- to 70- fold higher than in wild-type mice
• mutant mice that are pretreated with LPS before L. monocytogenes infection have a survival rate of about 35% compared to controls that have a 100% survival rate
• these LPS pre-treated mice have a higher number of liver microabcesses than controls after L. monocytogenes infection that were LPS pre-treated
