immune system
decreased T cell proliferation ( J:152472 )
• CD25+ T cells fail to proliferate when transferred into T cell-deficient recipients unlike similarly treated wild-type cells
• CD25- T cells exhibit reduced proliferation when transferred into T cell deficient recipients compared with similarly treated wild-type cells
decreased regulatory T cell number ( J:152472 )
• in the thymus and spleen
abnormal regulatory T cell physiology ( J:152472 )
• regulatory T cell turnover is impaired and suppressive function is lost
