Looks like an early flu season in the US.
Flu season is here and we're currently seeing a rise in flu emergency department visits, earlier than in previous seasons. Now is the time to get your flu shot! All New Yorkers 6 months and older should get an annual flu vaccine.

Large upload from Ontario yesterday, providing striking revelations about the evolution of PJ.2.1.
First, there is yet another hugely divergent branch of PJ.2.
This isn't one variant: it's four.
More & more, this resembles the emergence of BA.1/2/3. What is happening? 1/11

L'épidémie de #grippe débute particulièrement tôt aux Etats-Unis (mais aussi au Royaume-Uni notamment) : ce pourrait être "une saison incroyablement précoce" et "il se trame quelque chose".
Le virus H1N1 est largement majoritaire, mais avec une nouvelle mutation, la G155E, qui inquiète les chercheurs.
En effet, "certaines souches porteuses de cette mutation sont, dans certains cas, moins bien reconnues par les anticorps humains préexistants", d'après un preprint.
A suivre !

"When the next pandemic happens, there may be something that comes out of the blue, and we’ll be lacking the knowledge we had for COVID. What we’re trying to do is stockpile some of that knowledge ahead of time.” - Joe Grove, @UofGlasgow
A new open dataset adds predicted protein-complex structures from more than 2,800 viruses to the AlphaFold Database.

Claude has discovered a previously unknown enzyme system hidden in the DNA of bacteriophages. Beside the enzyme’s gene sits a long array of repeating DNA—a structure that looks somewhat similar to CRISPR.
We don’t yet understand what this system does, but only a handful of known systems share its features, and all of them are able to cut, copy, and paste DNA. Historically, the discovery of such programmable systems has helped revolutionize medicine. CRISPR, for instance, is now the foundation of genetic medicines. But it will take much more work to learn what this system does, and whether it can be put to similar use.

One of nine PJ.2.1 sequences uploaded from NYC today has A475V, which escapes some major class 1 antibodies. One of 2 two mAbs tested by @yunlong_cao that most potently neutralized PJ.2.1 (IC50=0.001) & to which it was much more vulnerable then XFG, is ~entirely escaped by A475V.
SARS-CoV-2 saltation variant PJ.2.1 has raised concerns over another JN.1-like event.
Here we found:
1. PJ.2.1 shows markedly higher ACE2 binding.
2. PJ.2.1's antigenicity remains comparable to the JN.1 family.
3. No increased immune evasion against human plasma.
While PJ.2.1 currently lacks the immune evasion capabilities of other contemporary strains (XFG, PQ.16.1.1, BA.3.2.2...), its robust baseline receptor-binding strength mirrors the early evolutionary trajectory of BA.2.86 to JN.1, necessitating continued genomic, epidemiological, and virological surveillance of the PJ.2.1 lineage.
Details can be found in the recent BioRxiv manuscript:

A new protein design optimization framework from the Baker Lab: RFOptimization.
Instead of generating more candidates, it rescues near-miss designs through RF3-guided mutation, Boltz/MPNN cycling, and AF3 filtering—boosting PPI success from 6.7% to 22.3%.
