The Structure of Elongated Viral Capsids [PDF]
There are many viruses whose genetic material is protected by a closed elongated protein shell. Unlike spherical viruses, the structure and construction principles of these elongated capsids are not fully known. In this article, we have developed a general geometrical model to describe the structure of prolate or bacilliform capsids.

Minimum energy paths for conformational changes of viral capsids [PDF]
In this work we study how a viral capsid can change conformation using techniques of Large Deviations Theory for stochastic differential equations. The viral capsid is a model of a complex system in which many units - the proteins forming the capsomers -

Self-Assembly of Fluorescent HIV Capsid Spheres for Detection of Capsid Binders [PDF]
The human immunodeficiency virus (HIV) capsid is a cone-shaped capsule formed from the viral capsid protein (CA), which is arranged into a lattice of hexamers and pentamers. The capsid comprises multiple binding interfaces for the recruitment of host proteins and macromolecules used by the virus to establish infection.

Tolerance to mutations in the foot-and-mouth disease virus integrin-binding RGD region is different in cultured cells and in vivo and depends on the capsid sequence context. [PDF]
Engineered RNAs carrying substitutions in the integrin receptor-binding Arg-Gly-Asp (RGD) region of foot-and-mouth disease virus (FMDV) were constructed (aa 141-147 of VP1 capsid protein) and their infectivity was assayed in cultured cells and suckling

Capsid-Incorporation of Antigens into Adenovirus Capsid Proteins for a Vaccine Approach [PDF]
Some viral vectors are potent inducers of cellular and humoral responses; therefore, viral vectors can be used to vaccinate against cancer or infectious diseases. This report will focus on adenovirus (Ad)-based vectors. Traditional viral-vector vaccination embodies the concept that the vector uses the host-cell machinery to express antigens that are ...

Hepatitis A Virus Capsid Structure [PDF]
Hepatitis A virus (HAV) has been enigmatic, evading detailed structural analysis for many years. Its recently determined high-resolution structure revealed an angular surface without the indentations often characteristic of receptor-binding sites. The viral protein 1 (VP1) β-barrel shows no sign of a pocket factor and the amino terminus of VP2 displays

Rhesus TRIM5α disrupts the HIV-1 capsid at the inter-hexamer interfaces [PDF]
TRIM proteins play important roles in the innate immune defense against retroviral infection, including human immunodeficiency virus type-1 (HIV-1). Rhesus macaque TRIM5α (TRIM5αrh) targets the HIV-1 capsid and blocks infection at an early post-entry ...

The rotavirus capsid is made up of three concentric protein layers. The outer layer, consisting of VP7 and VP4, is lost during virus entry into the host cell. Rotavirus field isolates can be adapted to high-titre growth in tissue culture by treatment with trypsin and by supplementing the culture medium with trypsin, which cleaves VP4 into two fragments,

Use of Capsid Integrity-qPCR for Detecting Viral Capsid Integrity in Wastewater
Quantifying viruses in wastewater via RT-qPCR provides total genomic data but does not indicate the virus capsid integrity or the potential risk for human infection. Assessing virus capsid integrity in sewage is important for wastewater-based surveillance, since discharged effluent may pose a public health hazard.

Atomic structures and deletion mutant reveal different capsid-binding patterns and functional significance of tegument protein pp150 in murine and human cytomegaloviruses with implications for therapeutic development. [PDF]
Cytomegalovirus (CMV) infection causes birth defects and life-threatening complications in immunosuppressed patients. Lack of vaccine and need for more effective drugs have driven widespread ongoing therapeutic development efforts against human CMV (HCMV)
