TWiV 70: Hacking aphid behavior

February 21, 2010

Hosts: Vincent Racaniello, Dickson Despommier, and Alan Dove

Vincent, Dickson, and Alan consider a broad spectrum antiviral against enveloped viruses, how a plant virus induces chemical signals in the host to maximize its spread, a new way to preserve viral vaccines at tropical temperatures, and the continuing story of XMRV and chronic fatigue syndrome.

    Regarding changing behavior of host by viruses, at least at cell level, analogy can be found in 'superinfection interference', which is a phenomena found in many viruses including retroviruses. Superinfection interference refers to a process, where cells that are infected by virus become resistant to subsequent infection by the same virus.

    Regarding altering aphid behavior by infection of a plant:

    Isn't rabies virus a virus that alters the behavior of its host to facilitate transmission?
    An increase in aggression coupled with copious salivation aids the transmission of the virus by bites.
