A beta-herpesvirus with fluorescent capsids to study transport in living cells. [PDF]
Fluorescent tagging of viral particles by genetic means enables the study of virus dynamics in living cells. However, the study of beta-herpesvirus entry and morphogenesis by this method is currently limited.

Neck and capsid architecture of the robust Agrobacterium phage Milano
Large gaps exist in our understanding of how bacteriophages, the most abundant biological entities on Earth, assemble and function. The structure of the “neck” region, where the DNA-filled capsid is connected to the host-recognizing tail remains poorly ...

Proton-Linked Dimerization of a Retroviral Capsid Protein Initiates Capsid Assembly [PDF]
In mature retroviral particles, the capsid protein (CA) forms a shell encasing the viral replication complex. Human immunodeficiency virus (HIV) CA dimerizes in solution, through its C-terminal domain (CTD), and this interaction is important for capsid assembly.

To get access to the replication site, small non-enveloped DNA viruses have to cross the cell membrane using a limited number of capsid proteins, which also protect the viral genome in the extracellular environment.

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 ...

Entrapment of viral capsids in nuclear PML cages is an intrinsic antiviral host defense against varicella-zoster virus. [PDF]
The herpesviruses, like most other DNA viruses, replicate in the host cell nucleus. Subnuclear domains known as promyelocytic leukemia protein nuclear bodies (PML-NBs), or ND10 bodies, have been implicated in restricting early herpesviral gene expression.

Assessment of the cross-protective capability of recombinant capsid proteins derived from pig, rat, and avian hepatitis E viruses (HEV) against challenge with a genotype 3 HEV in pigs [PDF]
Hepatitis E virus (HEV), the causative agent of hepatitis E, is primarily transmitted via the fecal-oral route through contaminated water supplies, although many sporadic cases of hepatitis E are transmitted zoonotically via direct contact with infected ...

Marseilleviridae is a family of giant viruses, showing a characteristic internal membrane with extrusions underneath the icosahedral vertices. However, such large objects, with a maximum diameter of 250 nm are technically difficult to examine at sub ...

A tail-like assembly at the portal vertex in intact herpes simplex type-1 virions [PDF]
Herpes viruses are prevalent and well characterized human pathogens. Despite extensive study, much remains to be learned about the structure of the genome packaging and release machinery in the capsids of these large and complex double-stranded DNA ...

Nuclear restriction of HIV-1 infection by SUN1
Overexpression of the human Sad-1-Unc-84 homology protein 2 (SUN2) blocks HIV-1 infection in a capsid-dependent manner. In agreement, we showed that overexpression of SUN1 (Sad1 and UNC-84a) also blocks HIV-1 infection in a capsid-dependent manner.
