immune system
N
• CD4 T cell differentiation is normal
• stimulated CD4+ T cells are larger than similarly treated wild-type cells
• in ovalbumin challenged mice
• under Th1 conditions, splenocytes produce less IFN-gamma than similarly treated wild-type cells
• under Th2 conditions, splenocytes produce less IL4, IL5, and IL13 compared with similarly treated wild-type cells
• in splenocytes under Th1 conditions
• in splenocytes under Th2 conditions
• in splenocytes under Th2 conditions
• in splenocytes under Th2 conditions
• ovalbumin-treated mice exhibit no increase in eosinophils and lymphocytes in the bronchoalveolar lavage fluid, reduced infiltration of cells in the peribronchiolar and perivascular regions of the lung and decreased mucus production unlike wild-type mice

respiratory system
• following methacholine treatment, ovalbumin sensitized and challenged mice fail to exhibit an increase in airway resistance unlike similarly treated wild-type mice
• following methacholine treatment, ovalbumin sensitized and challenged mice fail to exhibit airway hyperresponsiveness unlike similarly treated wild-type mice

cellular
• Th2 cells exhibit a dramatic increase in DNA methylation in the il4 promoter and CNS-1 region unlike similarly treated wild-type cells that exhibit a decrease in DNA methylation in this region

hematopoietic system
• stimulated CD4+ T cells are larger than similarly treated wild-type cells
• in ovalbumin challenged mice
• under Th1 conditions, splenocytes produce less IFN-gamma than similarly treated wild-type cells
• under Th2 conditions, splenocytes produce less IL4, IL5, and IL13 compared with similarly treated wild-type cells
