abstract：:The role of the cytoskeleton during viral infection is poorly understood. Here we show, using a combination of mutant and drug studies, that the intracellular enveloped form of vaccinia virus is capable of inducing the formation of actin tails that are strikingly similar to those seen in Listeria, Shigella and Rickett...

This property is known as positive stiffness. Less familiar is the concept of negative stiffness, where the deforming force and the resulting displacement are in opposite di...
