Transcript
CONTINUED⦠ïThe body fights influenza infections by developing antibodies to the hemagglutinin on the virus. When antibodies attach to hemagglutinin, they keep the virus from attaching to healthy cells which keeps the virus from infecting them. However, as each body cell is taken over by an invading virus, it sends out a distress signal as MHCs (transport chemicals from inside the cell to the cell surface) carry viral proteins to the surface which are brought to the attention of killer T-cells. Immediately they see the distress signal, coat the cell with toxic chemicals killing it and the virus.
