The role of adaptive immune responses in long COVID remains poorly understood, with contrasting hypotheses suggesting either an insufficient antiviral response or an excessive immune response associated with inflammatory damage. To address this issue, we set to characterize humoral and CD4+ T...

Abstract Long COVID (LC), a type of post-acute sequelae of SARS-CoV-2 infection (PASC), occurs after at least 10% of SARS-CoV-2 infections, yet its etiology remains poorly understood. Here, we used multiple omics assays (CyTOF, RNAseq, Olink) and serology to deeply characterize both global and...

https://www.mdpi.com/1422-0067/24/3/2010 Abstract Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) is a disabling multisystem illness in which individuals are plagued with fatigue, inflammatory symptoms, cognitive dysfunction, and the hallmark symptom, post-exertional malaise. While...

Abstract: SARS-CoV-2 causes profound changes in the sense of smell, including total smell loss. Although these alterations are often transient, many patients with COVID-19 exhibit olfactory dysfunction that lasts months to years. Although animal and human autopsy studies have suggested...

Alyssa, who is 13 and from Leicester, was diagnosed with T-cell acute lymphoblastic leukaemia in May last year. (…) Base editing allows scientists to zoom to a precise part of the genetic code and then alter the molecular structure of just one base, converting it into another and changing the...

Tevogen Bio is set to study the potential therapeutic use of its investigational Covid-19 T cell therapy, TVGN-489, in long Covid. The finding that none of the patients in the TVGN 489 proof-of-concept (POC) trial, treated for their initial Covid infection, developed long Covid to date is...

Pre-existing polymerase-specific T cells expand in abortive seronegative SARS-CoV-2 Leo Swadling, et al. Individuals with potential exposure to SARS-CoV-2 do not necessarily develop PCR or antibody positivity, suggesting some may clear sub-clinical infection before seroconversion. T-cells...

Pure speculation but maybe this line of research or the methods used in the paper to understand immune cell metabolic reprogramming via single-cell multiomics could eventually help explain whatever possible cellular metabolic changes that are triggered and persist in Long COVID and ME/CFS…...

This thread was split from Open Medicine Foundation (OMF) News I thought we could not conclude autoimmunity is likely out of the picture as long as we dont know how to target long lived plasma cells? I mean b-cells dont really matter at that point if im not mistanken, as the autoimmune plasma...
