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 macrophage intracellular killing of bacteria dendritic cell activation to become a mature APC CTL killing of viruses infected cell processing of virus peptides macrophage intracellular killing of bacteria dendritic cell activation to become a mature APC 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 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 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 ANSWER DOWNLOAD EXAMIANS APP
