Detrimental Effects of Anti-Nucleocapsid Antibodies in SARS-CoV-2 Infection, Reinfection, and the Post-Acute Sequelae of COVID-19

Pathogens
Antibody-dependent enhancement (ADE) is a phenomenon in which antibodies enhance subsequent viral infections rather than preventing them. Sub-optimal levels of neutralizing antibodies in individuals infected with dengue virus are known to be associated ...

Multiplexed Detection of Respiratory Viruses Using Surface Plasmon Resonance Spectroscopy With Ultrathin Carbon Nanomembranes

Advanced Healthcare Materials, EarlyView.
An ultrathin azide‐functionalized carbon nanomembrane (N3‐CNM) provides a versatile biointerface for antibody immobilization on gold SPR sensors. Integrated with a multichannel SPR platform, the functionalized surface enables label‐free, simultaneous detection of SARS‐CoV‐2, Influenza A, and RSV antigens, demonstrating the potential of CNM‐based ...

An Engineered HR1‐Stem Helix‐HR2 Trimeric Platform for Developing Broad‐Spectrum Coronavirus Vaccines

Advanced Science, EarlyView.
Sun et al. report a self‐assembling trimeric subunit vaccine platform termed RHS, which integrates the JN.1 receptor‐binding domain (RBD) with the heptad repeat 1 (HR1), stem helix (SH), and heptad repeat 2 (HR2) regions. The SARS‐CoV‐2 RHS vaccine elicits variant‐reactive RBD‐specific antibodies and cross‐reactive SH‐specific antibodies against ...

Multiplexed Flow Cytometric Approach for Detection of Anti-SARS-CoV-2 IgG, IgM and IgA Using Beads Covalently Coupled to the Nucleocapsid Protein [PDF]

, 2021
Flow cytometry has emerged as a promising technique for detection of SARS-CoV-2 antibodies. In this study, we described a new methodology to detect simultaneously IgG, IgM and IgA of SARS-CoV-2 nucleocapsid protein in human serum by flow cytometry.

An ATP‐Driven N Protein–DDX21 Molecular Switch Dynamically Controls SARS‐CoV‐2 RNA G‐Quadruplex Heterogeneity

Advanced Science, EarlyView.
An ATP‐driven molecular switch, comprising viral nucleocapsid (N) protein and host helicase DDX21, dynamically modulates SARS‐CoV‐2 RNA G‐quadruplex (G4) heterogeneity. These viral G4s feature non‐canonical ion‐dependence and act as energy‐sensitive structural checkpoints.

The nucleocapsid of vesicular stomatitis virus [PDF]

Science China Life Sciences, 2012
The nucleocapsid of vesicular stomatitis virus serves as the genomic template for transcription and replication. The viral genomic RNA is sequestered in the nucleocapsid in every step of the virus replication cycle. The structure of the nucleocapsid and the entire virion revealed how the viral genomic RNA is encapsidated and packaged in the virus.

Some Properties of Influenza Virus Nucleocapsids [PDF]

Journal of Virology, 1969
Nucleocapsids released from influenza virions by sodium deoxycholate sedimented heterogeneously in sucrose gradients. Highly infectious virus (complete) preparations yielded nucleocapsids with peak distributions at 64 and 56 S ; von Magnus type virus (incomplete) lacked 64 S nucleocapsids ...
