mortality/aging
• from 6 weeks of age

immune system
N
• mice exhibit normal response to experimental autoimmune encephalomyelitis
• from 6 weeks of age, mice exhibit a lymphoproliferative disorder unlike wild-type mice
• increased when induced by regulatory T cells
• however, anti-IL4 antibody abolishes Th2 instruction
• slightly decreased proportion in the spleen
• in splenic red pulp
• in the bronchoalveolar lavage fluid of ovalbumin-treated mice
• modestly
• ovalbumin-specific IgE in ovalbumin-treated mice
• CD4+ T cells and anti-CD3-stimulated splenocytes produce more Th2 cytokines (IL4, IL5 and IL10) compared with wild-type mice
• when injected into ovalbumin-immunized wild-type mice, regulatory T cells exacerbate Th2 immune responses in allergic reaction compared with wild-type cells
• however, regulatory T cells exhibit normal suppressive functions and stability
• regulatory T cells exhibit increased resistance to activation-induced cell death compared with wild-type cells
• from 6 weeks of age, mice exhibit larger size and cellularity of peripheral lymphoid organs compared with wild-type mice
• from CD4+ T cells
• from anti-CD3-stimulated splenocytes
• from anti-CD3-stimulated splenocytes
• from CD4+ T cells in the lungs
• from CD4+ T cells
• from anti-CD3-stimulated splenocytes
• from CD4+ T cells
• from anti-CD3-stimulated splenocytes
• massive infiltration in the lungs, stomach, skin and liver
• however, no lesions are observed in the kidney and colon
• from 6 weeks of age
• more severe when induced by ovalbumin with increased total cells and eosinophils in the bronchoalveolar lavage fluid
• severe at 16 weeks
