Somatic Evolution of a Germline Antibody Expands its Breadth to Neutralize Early SARS‐CoV‐2 Omicron Variants

Advanced Science, EarlyView.
Engineering of the 148‐germline (148‐GL) antibody reveals a roadmap for overcoming SARS‐CoV‐2 viral escape. By introducing four specific somatic hypermutations, the resulting 148‐M4 variant restores potent neutralization against Omicron BA.1 and BA.4/5.

Pilgrims and MERS-CoV: what’s the risk? [PDF]

Emerging Themes in Epidemiology, 2015
The risk of Middle East Respiratory Syndrome Coronavirus spreading globally is worrying, given the annual mass gathering of the Hajj and the year-long influx of pilgrims undertaking the Umrah. Based on the incidence in Saudi Arabia since June 2012, the most likely scenario given recent pilgrim numbers is estimated to be one case per Hajj, and three ...

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 ...

Intelligent Programmable Membrane Nanosponge for Early Virus Blocking

Advanced Science, EarlyView.
A smart programmable nanosponge (ACNPs) displays high‐density viral receptors on its membrane and encapsulates fusion inhibitors to capture virions at the infection source through competitive binding and blocks their entry through protease inhibition for ultra‐early cascade interception. This modular, mucus‐penetrating platform shifts antiviral defence

Drivers of MERS-CoV Emergence in Qatar [PDF]

Viruses, 2018
MERS-CoV (Middle East respiratory syndrome corona virus) antibodies were detected in camels since 1983, but the first human case was only detected in 2012. This study sought to identify and quantify possible drivers for the MERS-CoV emergence and spillover to humans. A list of potential human, animal and environmental drivers for disease emergence were

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.

Sarbecoviruses Suppress Innate Immunity by Recruiting PPM1A to Modulate STAT2 and ORF9b Phosphorylation

Advanced Science, EarlyView.
Sarbecovirus ORF9b recruits host phosphatase PPM1A to suppress innate immunity through dual mechanisms. PPM1A directly dephosphorylates ORF9b to sustain its activity and indirectly downregulates STAT2 phosphorylation to impair interferon signaling. Pharmacological inhibition of PPM1A restores antiviral responses and limits sarbecovirus replication ...

Characterization of Immune Responses to RBD‐SD1 Nanoparticle Vaccines Derived From ACE2‐Capable HKU5‐CoV‐2, NeoCoV, and HKU5 Merbecoviruses

Biotechnology and Bioengineering, EarlyView.
SpyCatcher‐mi3 nanoparticles presenting HKU5, NeoCoV, and HKU5‐CoV‐2 RBD‐SD1 induced strong, cross‐reactive IgG responses in immunized mice. The surrogate virus neutralization test demonstrated strong activity in sera from homologous vaccination. ABSTRACT Recent discoveries of merbecoviruses such as HKU5, NeoCoV, and HKU5‐CoV‐2 that use angiotensin ...
