immune system
decreased T cell proliferation ( J:109545 )
• purified T lymphocytes fail to expand or produce Il2 when stimulated with antiCD3 +/- antiCD28 costimulation; they do not respond to stimulation with PMA
decreased IgG level ( J:109545 )
• immunization with keyhole limpet hemocyanin doe not induce any production of KLH-specific IgG in mutants compared to wild-type
• IgG3 responses against TNP-Ficoll are absent for at least 21 days
decreased IgM level ( J:109545 )
• immunization with keyhole limpet hemocyanin doe not induce any production of KLH-specific IgM in mutants compared to wild-type
• IgM responses against TNP-Ficoll are absent for at least 21 days
abnormal dendritic cell physiology ( J:111706 )
• impaired zymosan-induced production of Tnfa in bone marrow dendritic cells
• impaired fungal cell-induced production of Tnfa, Il2, and Il10 in bone marrow dendritic cells
