This preprint identified SARS-CoV-2 RNA in the bone marrow megakaryocytes (MK) of severe COVID-19 patients. Then - in mice - they showed these infected MKs promoted formation of non-neutralizing afucosylated anti-spike IgG antibodies + pulmonary thrombosis:

They hijack the metabolism of the cells they infect. Their proteins directly modulate human gene expression + the activity of the immune system. They can infect nearly every human body site. Do not underestimate this.

The finding below is consistent with this Harvard preprint () that used sensitive Simoa assays on #LongCovid blood. They found SARS-CoV-2 spike antigen in a majority of patients up to 12 mo. post-diagnosis (suggesting active #SARS -CoV-2 reservoir in tissue)

@meghanor Yes! But also logical that the virus might just be “hiding out” in the area of the body where a patient has ongoing symptoms. For example this team found SARS-CoV-2 RNA/protein in olfactory bulb tissue of patients with loss of smell after COVID-19:

I share this concern👇 #SARS -CoV-2 persistence in tissue (in patients with #LongCovid or otherwise) should be a central research focus in the world right now. Our @polybioRF team is working to set up collaborations on the topic, but we need even more scientists to jump in!

I am concerned about sub-threshold neutralizing antibodies tied to disease enhancing antibodies leading to greater persistence of COVID. Those with long COVID are canaries in the coalmine and we should be directing far more attention to the pathogenesis underlying these cases.

Them: Microclots and platelet hyperactivation in #LongCovid can't be quantified by conventional standards, so we shouldn't use it as a biomarker Us: Hold our beer(s). Step 1: Take blood, spin blood, stain blood, look at blood under a microscope and capture an image of it 1/

And the million dollar question is: what were the IgG antibodies in the blood of the #fibromyalgia patients created in response to? Certainly a broad range of pathogens/organisms induce IgG antibody production

Thanks for the shoutout @PutrinoLab ! I helped coin the term “infection-associated chronic disease” to describe conditions like ME/CFS & LongCovid. It’s an alternative to “post-viral disease” which assumes full pathogen clearance when that should be a hypothesis not an assumption

Ok. Another request, another 🧵. Today, we address the strained relationship between psychology, psychiatry and #LongCovid . Much of this may also apply to #pwME and other infection-associated chronic illnesses (h/t again @microbeminded2 ) and other “invisible” illnesses (1/n)
