immune system
decreased thymocyte number ( J:152041 )
• there are almost 10-fold lower thymocytes compared to controls
abnormal T cell subpopulation ratio ( J:152041 )
• the percentage of single-positive thymocytes is increased
• the percentage of double-positive thymocytes is decreased compared to controls
abnormal NK T cell morphology ( J:152041 )
• 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
decreased splenocyte number ( J:152041 )
• splenocyte numbers are almost cut in half
increased IgG1 level ( J:152041 )
