In vitro-assembled alphavirus core-like particles maintain a structure similar to that of nucleocapsid cores in mature virus.

In vitro-assembled core-like particles produced from alphavirus capsid protein and nucleic acid were studied by cryoelectron microscopy. These particles were found to have a diameter of 420 A with 240 copies of the capsid protein arranged in a T=4 icosahedral surface lattice, similar to the nucleocapsid core in mature virions. However, when the particles were subjected to gentle purification pr...

Generating enveloped virus-like particles with in vitro assembled cores.

Alphaviruses are comprised of a nucleocapsid core surrounded by a lipid membrane containing glycoprotein spikes. Previous work demonstrated that in vitro assembled core-like particles are similar in structure to the nucleocapsid core in the native virus. Here we demonstrate that in vitro assembled core-like particles can be inserted into viral glycoprotein-expressing cells to generate enveloped...

Rescue of infectious particles from preassembled alphavirus nucleocapsid cores.

Alphaviruses are small, spherical, enveloped, positive-sense, single-stranded, RNA viruses responsible for considerable human and animal disease. Using microinjection of preassembled cores as a tool, a system has been established to study the assembly and budding process of Sindbis virus, the type member of the alphaviruses. We demonstrate the release of infectious virus-like particles from cel...

Self-assembled virus-like particles with magnetic cores.

Efficient encapsulation of functionalized spherical nanoparticles by viral protein cages was found to occur even if the nanoparticle is larger than the inner cavity of the native capsid. This result raises the intriguing possibility of reprogramming the self-assembly of viral structural proteins. The iron oxide nanotemplates used in this work are superparamagnetic, with a blocking temperature o...

In vitro assembly of alphavirus cores by using nucleocapsid protein expressed in Escherichia coli.

The production of the alphavirus virion is a multistep event requiring the assembly of the nucleocapsid core in the cytoplasm and the maturation of the glycoproteins in the endoplasmic reticulum and the Golgi apparatus. These components associate during the budding process to produce the mature virion. The nucleocapsid proteins of Sindbis virus and Ross River virus have been produced in a T7-ba...
