Document Summary
Influenza virus: a rna virus consisting of 8 rna segments (inside the cell, on the outside of the cell, the influenza virus has haemagglutinin (ha) and. Involves an rna polymerase in order to replicate rna from rna. Ha: can bind to receptors on the surface of the cell (a key to the virus to enter into a cell) Sialic acid keeps the virus attached to the cell good for us, since the virus cannot infect any other cells, but bad for the virus. Na: detaches the virus from the infected cell so that the virus can continue infecting other cells: tamiflu is used to prevent na from detaching from the cell. Antibodies against influenza virus: anti ha antibodies and anti na antibodies used to stop the activity of na and. Used to block the virus from binding to its receptor.
