On episode #326 of the science show This Week in Virology, the sternutating TWiVers discuss preventing infection of cells and animals by a soluble CD4-CCR5 molecule that binds to HIV-1 virus particles. You can find TWiV #326 at www.microbe.tv/twiv.

Because viruses must bind to cell surface molecules to initiate replication, the use of soluble receptors to block virus infection has long been an attractive therapeutic option. Soluble receptors have been developed that block infection with rhinoviruses and HIV-1, but these have not been licensed due to their suboptimal potency. ...

On episode #325 of the science show This Week in Virology, Vincent visits the 'Little Apple' and speaks with Rollie and Lorena about their work on mosquito-born viruses and baculoviruses. You can find TWiV #325 at www.microbe.tv/twiv.

An otherwise balanced review of selected aspects of Ebolavirus transmission falls apart when the authors hypothesize that 'Ebola viruses have the potential to be respiratory pathogens with primary respiratory spread.' The idea that Ebolavirus might become transmitted by the respiratory route was suggested last year by Michael Osterholm in a Times OpEd. ...

The entry of enveloped viruses into cells begins when the membrane that surrounds these virus particles fuse with a cell membrane. The process of virus-cell fusion must be tightly regulated, to make sure it happens in the right cells. The fusion activity of measles viruses isolated from the brains of AIDS ...
