episode 743: Shape-shifting viruses


The TWiVsters explain how the shape of pleomorphic virus particles – spherical or filamentous – determines the probability of virus attachment and fusion, and resistance to selective pressure such as antibodies that block cell entry.

episode 742: De-fusing COVID-19


TWiV reviews a drug screen for inhibitors of syncytium formation, the fusing of cells caused by SARS-CoV-2, which reveals that the process is regulated by a calcium-activated ion channel and scrambles that is inhibited by the anti-parasite drug...
