Could Autoantibodies Help Explain Long COVID? At #ISLCPAIS, Dr. Jeroen den Dunnen shares early research suggesting autoantibodies from some people with Long COVID can affect muscle, nerve, heart and blood-vessel cells in laboratory models. #LongCOVID #PAIS #Autoimmunity

Our paper is (finally) out in @cp-cellrepmed.bsky.social: antibodies from #LongCOVID patients transfer symptoms to mice, pointing to a potential causal role for autoimmunity: www.cell.com/cell-reports... @amsterdamumc.bsky.social @umcutrecht.bsky.social 1/12

Transfer of IgG from long COVID patients induces symptomology in mice
Chen et al. show that long COVID IgG induces pain-associated behaviours in mice. Pathogenic IgG effects vary across biomarker-defined subgroups, which exhibit specific, long-lasting autoantibody signa...

For the first time, a prestigious Dutch #VICI grant (€ 1.5M) has been awarded to research on post-acute infection syndromes (PAIS). I’m deeply grateful for this opportunity to further indentify the underlying mechanisms: www.zonmw.nl/en/news/39-r...

We already knew that severe acute #COVID19 is induced by pathogenic IgG. But now Lynn Mes & @oliverch77.bsky.social show in @eurjimmunol.bsky.social that IgA2 adds even more fuel to the fire 🔥: onlinelibrary.wiley.com/doi/10.1002/...

Long COVID patients show immunological imprinting and impaired antibody class switching: fewer IgG/IgA antibodies against SARS-CoV-2 spike, but more against seasonal coronaviruses. Interesting finding by my PhD student Ashwin Mak in J Med Virol: onlinelibrary.wiley.com/doi/10.1002/... 1/6

It was such a pleasure to have @resiapretorius.bsky.social over @amsterdamumc.bsky.social! Happy to see the #microclots assays worked right away 😀. We can now screen and select #LongCovid patients, to see whether we can also detect microclots using total body PET scan (powered by #ZonMw).
