immune system
• Pam3Cys-treated mice exhibit reduced Ly6Chi monocyte emigration from the bone marrow compared with similarly treated wild-type mice
• macrophages are unresponsive to macrophage activating lipopeptide 2 kD (MALP-2) and tripalitoyl cysteinyl lipopeptide (Pam3CSK4) (J:70578)
• response of macrophages to synthetic analogs of B. burgdorferi and T. pallidum lipopeptides is completely abrogated (J:70578)
• normal response of macrophages to lipopeptides of other bacterial origins (J:70578)
• activation by peptidoglycan, zymosan, and propionibacterium acnes fails (J:103464)
• reduced production of TNF alpha in response to Porphyromonas gingivalis (J:130138)
• cultural supernatant from P gingivalis stimulated peritoneal macrophage fails to stimulate osteoclast formation
• reduced after both 30 and 60 minutes of reperfusion following ventricular ischemia
• reduced after 30 but not 60 minutes of reperfusion following ventricular ischemia
• cytokine production by macrophages in response to both diacylated (macrophage activating lipopeptide 2 kD [MALP-2]) and triacylated lipopeptides (tripalitoyl cysteinyl lipopeptide [Pam3CSK4]), and synthetic analogs of B. burgdorferi and T. pallidum lipopeptides) is completely abrogated
• macrophages produce no NO and IL-12 in response to MALP-2 together with IFN-gamma or to Pam3CSK4
• MEFs treated with MALP-2 or Pam3CSK4 fail to produce IL-6
• macrophages produce no TNF-alpha in response to MALP-2 or Pam3CSK4 (J:70578)
• macrophages show impaired TNF-alpha production in response to heat-killed mycoplasma (J:70578)
• macrophages show no TNF-alpha production in response to the native mycobacterial 19-kDa lipoprotein and a synthetic triacylated lipopeptide, but respond normally to diacylated lipoprotein (J:103395)
• leukocyte influx into cerebrospinal fluid occurs but is less than in controls after S. pneumoniae injection into the spinal canal
• no deaths during the experimental period from meningitis induced by Streptococcus pneumoniae

muscle
N
• MCP-1 (monocyte chemoattractant protein-1) release from isolated mouse aorta smooth muscle cells (MAoSMC) by stimulation with dsRNA is normal relative to controls

homeostasis/metabolism
• recovery of post-ischemic left ventricular contractile performance is greater than controls
• reduced after both 30 and 60 minutes of reperfusion following ventricular ischemia
• reduced after 30 but not 60 minutes of reperfusion following ventricular ischemia
• relative infarction size is significantly smaller than in controls 72 hours after middle cerebral artery occlusion

liver/biliary system
