immune system
• CD4+ T cells were first transfected with a cre recombinase vector and then treated with dipthera toxin so that surviving T cells only expressed the mutant Lattm1Mal allele
• when activated and transferred into T cell deficient hosts, these T cells cause splenomegaly, lymphadenopathy and secrete high levels of IL-4
• these abnormal T cells promote B cell activation in their hosts leading to high levels of IgG1 and IgE
• T cells are not pathogenic when transferred into MHC-II deficient hosts or in the absence of CD28 signalling
