immune system
abnormal dendritic cell differentiation ( J:169170 )
• bone marrow derived dendritic cell maturation induced by IL4 is impaired compared with wild-type cells
• however, LPS treatment partially rescues maturation
abnormal dendritic cell physiology ( J:169170 )
• bone marrow-derived dendritic cells treated with LPS and incubated with CD3-enriched cells elicit less T cell proliferation compared with similarly treated wild-type cells
• bone marrow-derived dendritic cells treated with LPS and pulsed with ovalbumin fail to induce increased production of IFN-gamma from Tg(DO11.10)10Dlo T cells compared with similarly treated wild-type cells
decreased interleukin-12 secretion ( J:169170 )
• in bone marrow-derived dendritic cells grown in LPS, GM-CSF alone, or GM-CSF with IL4
decreased tumor necrosis factor secretion ( J:169170 )
• in LPS-treated bone marrow-derived dendritic cells

immune system
abnormal T cell differentiation ( J:71804 )
• partial rescue of block at double-positive stage observed in Zap70tm1Weis homozygotes

decreased CD4-positive, alpha-beta T cell number ( J:71804 )
• thymocytes mature to the single-positive stage and proceed to become mature T cells, but overall number of mature CD4+ T cells is less than that of wild-type
