Influenza Virus Capsule Model

Enhance your virus lesson with our Influenza Virus Capsule.

Influenza is an RNA virus with a roughly spherical lipid envelope, which is colored yellow on our schematic model. The outside of the virus capsule is covered with 3 specific proteins: hemagglutinin (purple), neuraminidase (pink) and the M2 channel (blue). These 3 proteins are involved in virus docking, endocytosis and fusion of the viral membrane to the host cell, the release of newly budded virus from infected cells, and acidification of the virus core and release of the segmented viral RNA. The specific sub-types and combinations of the hemagglutinin (H) and neuraminidase (N) on the surface of the virus capsule categorize the strain of the virus. The viral RNA is represented by 8 segments of RNA -- some are colored red and some colored yellow -- to represent a reassorted virus emerging from a host cell simultaneously infected with a swine flu virus and an avian flu virus (H1N1 swine flu).

The 4'' and 6'' models are made of plaster by rapid prototyping and should be handled with care. They will break if dropped, held tightly or handled roughly.

Teacher Tip

Always have your students use plaster models over a table to minimize breakage. Simple breaks can usually be repaired with super-glue.
