Kоlb - Inbоrn Errоrs of Immunity You hаve а mutаnt mouse that is defective in generating IgG antibody responses to immunization with an attenuated virus vaccine. To begin to determine what is causing the immunodeficiency, you perform an adoptive transfer experiment wherein you transplant T and B cells from wild-type (WT) or mutant mice into RAG-deficient mice. The resultant mice are then immunized and virus specific antibody titers are measured 2 weeks later. The results are shown below. Adoptive Transfer Antibody response WT B cells + WT T cells ++++ Mutant B cells + WT T cells ++++ WT B cells + Mutant T cells - Mutant B cells + Mutant T cells - (A) Based on the results of this experiment, which ONE of the following genes is the most likely defective gene and briefly define why. (2 points) TACI or BTK or NEMO or CD40 or CD40-ligand (B) Briefly define the clinical symptoms that a patient with this mutation is likely to present with. (2 points) (C) State the approximate age at which you would expect these symptoms to start and briefly define why. (2 points)
