🧠🦠 Non-polio enteroviruses (NPEV) cause neurological complications like meningitis, encephalitis & acute flaccid paralysis—but we still don't fully understand HOW these viruses disrupt neural function!
Here we have evidence that NPEV compromise neurotransmission 👇

Beautiful work from @efodor.bsky.social and Jonathan Grimes' labs - the first full structure of the influenza A virus NEP protein, and a clear indication that its role in viral replication is more nuanced that first thought

First evidence in Europe of highly pathogenic avian influenza virus H5N1 infection in a dairy cow. Antibodies against H5N1 detected in a cow with mastitis and respiratory signs on a Dutch dairy farm at the end of December. A cat on that farm had died from H5N1. www.tweedekamer.nl/downloads/do...

However, highly pathogenic avian influenza H5N1 no longer occurs just in birds. Worldwide, nearly 100 species of mammals have been found positive, including farmed maammals like cows, pigs and minks, and wild mammals like seals, sea lions, foxes and skunks. www.nature.com/articles/s41...

Second, it raises the question whether national governments should start systematic avian influenza in mammals. Currently, this is only performed in birds.

This first probable case of highly pathogenic avian influenza in a dairy cow in Europe raises two points. First, it suggests that virus incursion is possible in the Dutch housing system, which differs from that in the southern U.S., where cows were first infectted. www.science.org/content/arti...

I am super happy to share this paper in its final form. We used FIB milling to "dig in to" cell lines and mouse brains infected with tick-borne flaviviruses, followed by cryo-ET to study the virus replication. It's open access, so have a look!

#H5N1 : An infected herd was recently detected in Wisconsin, and genome sequencing indicates that this is yet another spillover event, making it the fourth detected one.

How do these spillovers happen and why are they restricted, so far, to the US?

www.aphis.usda.gov/news/agency-...
WASHINGTON, D.C., December 19, 2025—On December 14, 2025, USDA’s Animal and Plant Health Inspection Service (APHIS) announced the first detection of highly pathogenic avian influenza (HPAI) in a dairy herd in Wisconsin. On December 17, the National Veterinary Services Laboratories (NVSL) completed whole genome sequencing and confirmed that the virus is H5N1 clade 2.3.4.4b genotype D1.1. Analysis indicates that this detection is a new spillover event from wildlife into dairy cattle, separate from previous events. Key Points Most detections in U.S. dairy herds have resulted from movements linked to the original spillover event that occurred in the Texas Panhandle in late 2023, involving the B3.13 strain. In early 2025, through the National Milk Testing Strategy, USDA detected two spillover events in Nevada and Arizona dairy herds. Both were identified early, and no further herd infections occurred through animal movements. These events involved the D1.1 strain. The Wisconsin herd, also detected through the National Milk Testing Strategy, represents a new, separate spillover event and involves the D1.1 strain. At this time, no additional dairy herds have been identified as infected in association with this event.

How does fever work?

Our new Science paper shows how elevated body temperature can protect against severe influenza and that avian-origin viruses escape this defence.

This is likely one reason why bird flus and some pandemic influenzas can be so severe.🧵
