immune system
• mice have lower secretion of keratinocyte chemokine (CXCL1) in the airway after 1 ng dose of LPS
• mice have higher secretion of CXCL1 in the airway after 100 ng dose of LPS compared to LPS-treated controls
• there is less secretion of TNF in the airway after 1 ng dose of LPS compared to LPS-treated controls
• mice are resistant to airway sensitivity induced by low intranasal doses of LPS but have augmented inflammatory responses to high doses of LPS
• mice have lower neutrophil influx and secretion of TNF and keratinocyte chemokine in the airway after 1ng dose of LPS
• mice have enhanced neutrophil influx and cytokine secretion after a 100ng LPS dose compared to controls
• histological scoring confirms more severe inflammation in the lungs 6 and 22 hours after 100 ng LPS administration
• mice are resistant to airway sensitivity induced by low intranasal doses of LPS but have augmented inflammatory responses to high doses of LPS
• mice have lower neutrophil influx into the airways with 1ng dose of LPS but higher neutrophil influx with 100ng doses of LPS

immune system
• OVA-sensitized mice do not develop significant airway reactivity following beta-methylcholine challenge
• lung inflammation after methylcholine challenge is different with decreased mucin production and some inflammatory loci shifted to airway regions
• nitrous oxide is not produced in the challenged lungs as occurs in wild-type controls

homeostasis/metabolism
• OVA-sensitized mice do not produce nitrous oxide in the lungs in response to airway challenge as occurs in wild-type controls

immune system
• lipopolysaccharide-binding protein is absent from the blood
• whole blood produces little TNF in response to ex vivo exposure to LPS
• little TNF response to LPS also occurs when mutant plasma is added to wild-type blood cells
• no differences are seen when LPS is administered in vivo

homeostasis/metabolism
• whole blood produces little TNF in response to ex vivo exposure to LPS
• little TNF response to LPS also occurs when mutant plasma is added to wild-type blood cells
• no differences are seen when LPS is administered in vivo
• mice are resistant to liver injury caused by 4 weeks of ethanol administration
• increases in liver-to-body weight ratio are decreased by almost 20%
• serum transaminase levels are about two-thirds less than ethanol fed controls

liver/biliary system
• mice are resistant to hepatitis caused by long term ethanol feeding
• effects of 4-week ethanol feeding are blunted as measured by several parameters
• increases in liver-to-body weight ratio are decreased by almost 20%
• serum transaminase levels are about two-thirds less than ethanol fed controls
