immune system
• there are almost 10-fold lower thymocytes compared to controls
• the percentage of single-positive thymocytes is increased
• the percentage of double-positive thymocytes is decreased compared to controls
• some CD8-single positive NKT cells are found in the liver
• iNKT T cells have a bias towards expressing a receptor encoded in part by the TCRVbeta8 gene segment
• splenocyte numbers are almost cut in half
• IgG1 levels are increased about 5-fold
• IgG2a levels are decreased about 10-fold
• GM-CSF levels are more than 10-fold higher than controls 4 hours after alphaGalCer injection
• IFN-gamma levels are more than 10-fold higher than controls 4 hours after alphaGalCer injection
• increased IFN-gamma levels result from increased numbers of iNKT cells
• IL-10 levels are more than 10-fold higher than controls 4 hours after alphaGalCer injection
• IL-2 levels are more than 10-fold higher than controls 4 hours after alphaGalCer injection
• IL-4 levels are more than 10-fold higher than controls 4 hours after alphaGalCer injection
• increased IL-4 levels result from increased numbers of iNKT cells

liver/biliary system
