Disease Associated with Immune System Chronic granulomatous disease results from a failure to perform oxidative burst. This deficiency would be most likely to interfere with CTL killing of viruses infected cell processing of virus peptides dendritic cell activation to become a mature APC macrophage intracellular killing of bacteria CTL killing of viruses infected cell processing of virus peptides dendritic cell activation to become a mature APC macrophage intracellular killing of bacteria ANSWER DOWNLOAD EXAMIANS APP

Disease Associated with Immune System DiGeorge's syndrome is characterized by the lack of a thymus The mouse model closest to this human disease would be a nude mouse recombinant mouse for CD3 knock-out mouse for RAG-1 and RAG-2 knock-out mouse for a thymus nude mouse recombinant mouse for CD3 knock-out mouse for RAG-1 and RAG-2 knock-out mouse for a thymus ANSWER DOWNLOAD EXAMIANS APP
Disease Associated with Immune System X-linked hyper IgM syndrome, resulting in high levels of serum IgM and low levels of serum IgG, is caused by a defect in CD40L expression. The specific immune event that would be prevented by a defective CD40L would be failure of B cells to provide co-stimulation for Th2 activation activation of B cells by T-independent antigens failure of Th2 cells to provide co-stimulation for B cell isotype switching failure of Th2 cells to provide co-stimulation for B cell proliferation failure of B cells to provide co-stimulation for Th2 activation activation of B cells by T-independent antigens failure of Th2 cells to provide co-stimulation for B cell isotype switching failure of Th2 cells to provide co-stimulation for B cell proliferation ANSWER DOWNLOAD EXAMIANS APP
