immune system
insulitis ( J:113109 )
• mice show less insulitis compared to non-transgenic double nulls
decreased regulatory T cell number ( J:113109 )
• mice have 0.3% CD4+CD25hiCD62L+ regulatory T cells compared to 4% in NOD controls
decreased susceptibility to autoimmune diabetes ( J:113109 )
• mice show 40% suppression of diabetes development compared to non-transgenic double null animals

hematopoietic system
decreased regulatory T cell number ( J:113109 )
• mice have 0.3% CD4+CD25hiCD62L+ regulatory T cells compared to 4% in NOD controls

immune system phenotype ( J:113109 )
N
• B and T cells develop normally in transgenic mice; peripheral B and T cells show similar development and function to polyclonasl stimuli like LPS, anti-IgM, anti-CD3 and anti-CD28 as wild-type cells
abnormal B cell physiology ( J:113109 )
• B cells from mutants inhibit proliferation and cytokine production by wild-type T cells in culture
