Emergence of a novel GII.17 variant is associated with immune evasion rather than an altered HBGA-binding profile In 2024, a new Norovirus variant appeared due to antigenic drift, causing more infections. journals.plos.org/pl... 1/5

Emergence of a novel GII.17 variant is associated with immune evasion rather than an altered HBGA-binding profile

Author summary Noroviruses are the leading cause of acute gastroenteritis worldwide and are responsible for large numbers of outbreaks each year. New norovirus variants can spread rapidly when they are no longer well recognized by existing immunity in the population. In 2024, a new GII.17 variant became increasingly common in several regions, raising questions about why this virus was able to spread so successfully. In this study, we compared this new variant with other GII.17 viruses that circulated in 2005, 2014, and 2015. We examined how well these viruses could attach to molecules and tissues in the human gut and how well they were recognized by antibodies in human serum samples collected over time. We found that the 2024 variant was less well recognized by existing antibodies than some earlier strains, suggesting that it had changed in ways that may help it evade prior immunity. In contrast, its ability to bind to human gut-related targets was broadly similar to that of recent other variants. Together, our findings suggest that changes in immune recognition, rather than major changes in binding specificity, contributed to the recent emergence of this GII.17 variant.

Success in the @ukri.org BBSRC ALERT biosciences equipment funding call means our JEOL F2-Cryo will be getting an upgrade. After 12 years of service, it's time for a new camera to restore the microscope to best-in-class performance and giving our users the best possible data.

Fantastic to have this out! As ever, I'm immensely grateful to all co-authors for their support, advice, and resource provision. This was a real collaborative effort, and highlights the potential of VP2 as a viable target for calicivirus antivirals- exciting stuff!

Amazing work from Charlotte Lewis - our latest preprint describes structure guided development of an antiviral peptide, targeting VP2 portal assembly - a strategy that may have broad application to treat or prevent calicivirus disease. www.biorxiv.org/content/10.6...

The OG of outbreak viruses on cruise ships needed to remind everyone who is boss. 115 infected on the carribean princess cruise ship in an ongoing outbreak. Sounds like my idea of hell on earth. Trapped at sea on a ship full of people with vomiting and diarrhea. abcnews.com/Internationa...

115 people sickened in norovirus outbreak on cruise ship: CDC

The outbreak was reported to the CDC on Thursday, during the cruise ship's April 28 to May 11 voyage.
