@VirusesImmunity @alex_winnett @S_Tabachnikova @ismagilovlab Why don't you ask why many with #LongCovid can't get vaccinated without clinically deteriorating.
That would be useful.

Implication: if we want vaccines that limit transmission, not just disease, we may need to seed TRM in the nose. Current intramuscular vaccines do this to some extent, but poorly. Prime & Spike strategies do this very well. As always, very grateful to all who contributed 🙏🏼 https

But it's the Type II IFN (IFN-γ) that actually appears to matter for controlling viral replication. Earlier mucosal IFN-γ correlated with 10–100x lower viral load. COVID vaccination was associated with earlier Type II IFN responses. (4/) https://t.co/oRavIREfFD

How does vaccination help beyond antibodies? Vaccinated individuals had higher tissue-resident memory T cell (TRM) signatures in the nasal mucosa and mounted Type II IFN responses earlier. This points to mucosal TRM as a key mechanism — and a target for next-gen vaccines. (5/) ht

We found that Type I IFNs fired fast and synchronously across all three sites — even before the virus was detectable locally. Remarkable coordination. Typically, SARS-CoV-2 was detected first in the oral cavity/ oropharynx, then in the nasal cavity. (3/) https://t.co/Hf6odPgUdE

New preprint by @alex_winnett @S_Tabachnikova et al.! We asked: which cellular immune signals control viral replication in the nose during the first days of SARS-CoV-2 infection — and how do they change with vaccination? With @ismagilovlab (1/)

We collected 1,237 daily swabs from the nasal, oral, and oropharyngeal sites of people starting before naturally acquired COVID-19 infection. This temporally dense, multi-site mucosal sampling gave us a unique platform to probe the immune protective signature via RNAseq. (2/) htt

@VirusesImmunity @keylas3 @PutrinoLab So you mean inducing spike protein production by genetic therapy caused auto immunity.
Who'd have thought hey.
Why are you still calling it "Long COVID"?

Whether this autoantibody subgroup of Long COVID could benefit from FcRn inhibitors, B cell depletion therapies, etc., needs to be examined in future studies. So grateful to all co-authors & participants dedicated to better understanding the pathophysiology of Long COVID🙏🏼 https:

This work builds on prior work by other groups, such as @DrDenDunnen Chen et al. DOI: 10.1016/j.xcrm.2026.102693, Mignolet et al. DOI: 10.1007/s00401-026-03019-0, and of course, the original demonstration in fibromyalgia Goebel et al. DOI: 10.1172/JCI144201

When purified IgG from patients with LC was transferred into naive healthy mice, it was sufficient to induce heightened heat sensitivity. With help from Tamas Horvath group. IgG that caused heat pain in mice came from patients reporting chronic pain! https://t.co/SivE4mb8Qk

The nociceptor neurons responsible for sensing heat in the skin were damaged shortly after the patients' IgG injection. We also see human IgG around the remaining nociceptor in the skin. Analysis by @bakermind https://t.co/SlIaFCHFZN

Using tissue-based staining, a human proteome array, ELISA, IgG-pull down and mass spec, we identified a wide array of autoantibodies in those with LC. IgG targeting neurological antigens, such as NMDAR, were elevated in LC. Collab with CellTrend and @C_Scheibenbogen 🙏🏼 https://t

With SeromYx, we found that autoantibodies to MED20 in LC have undergone class switching to IgG from IgM, bind to many FcgRs, and induce robust phagocytosis when in immune complexes compared to IgG from control participants https://t.co/2L7ni6OTLA

Excited to share our study by @keylas3 et al. on pathological autoantibodies in people with Long COVID. We asked whether IgG in patients with Long COVID bind to human tissues/antigens and cause pathologies when transferred into mice. With @PutrinoLab

'STORM' is a short documentary about Scott Hugo. A story of Long COVID's impact on his life and family - a reminder of what is at stake in research on Long COVID.
His resilience humbles me.
Please watch and share 🙏🏼

To all aspiring young #WomenInSTEM:
Mentee: Should I avoid being pregnant while trying to secure a faculty position?
Me: Be pregnant & go on interviews. If they don’t welcome you with open arms and offer childcare options, they don’t deserve you. #KnowYourWorth
