This lesson showed all the cell types in the immune system.1 True False Interferon causes many anti-viral proteins to be made, and we know exactly what each one does.1 True False All the viral sensors are designed to stimulate production of interferon (IFN).1 True False Why do the phagocytes (roaming eaters) have MHC-2 clips on their surface?1 For showing bits of protein to T helper cells. For sensing viral dsRNA. For communication with other phagocytes. Only for identification as "self." The Y-shaped antibodies that B cells make will stick to any virus.1 True False Which of these is NOT a sensor molecule?1 TLR-3 RIG-1 MHC-1 MDA-5 Which of these cells will eat anything that is covered in Y-shaped antibodies?1 B cell NK cell T cell macrophage Which of these cells has a perforin gun?1 B cell T helper macrophage dendritic cell NK Which organelle digests things?1 mitochondria ER lysosome Golgi body What are granzymes?1 Enzymes that digest all the proteins in the host cell. Chemical toxins that tell the cell to shred its DNA. Granular proteins that self-assemble to make a hole. How does RIG-1 work?1 It goes into the nucleus when triggered. It kills viruses when triggered. It bends in half when triggered. Its shape straightens out when it is trigger. Skin is a good barrier against viruses because the outer layer is made of dead cells.1 True False Some of your cells were built with atoms and molecules that used to be part of viruses.1 True False Which cell can feel the absence of MHC-1 flags?1 B cell macrophage killer T cell NK Killer T cells must get permission from T helper cells before killing a body cell.1 True False VIRUSES lesson 8: Viruses Inside Cells VIRUSES lesson 10: Vaccines and anti-virals Back to: VIRUSES lesson 9: The Body Fights Back
