autoantibodies

Abstract Background Activation of the immune system is implicated in the Post-Acute Sequelae after SARS-CoV-2 infection (PASC) but the mechanisms remain unknown. Angiotensin-converting enzyme 2 (ACE2) cleaves angiotensin II (Ang II) resulting in decreased activation of the AT1 receptor and...

https://pubmed.ncbi.nlm.nih.gov/34484936/ Abstract Objective: Postural tachycardia syndrome (POTS), the most common form of dysautonomia, may be associated with autoimmunity in some cases. Autoantibodies against the ganglionic acetylcholine receptor (gAChR) have been reported in a minority of...

Abstract Functional autoantibodies directed to the M2 muscarinic acetylcholine receptor (M2R) could affect the heart rate directly by altering cardiac M2R activity and/or indirectly by changing vagal-mediated cardiac M2R activity. We measured M2R autoantibody activity in sera from 10 subjects...

Autoantibodies to Vasoregulative G-Protein-Coupled Receptors Correlate with Symptom Severity, Autonomic Dysfunction and Disability in Myalgic Encephalomyelitis/Chronic Fatigue Syndrome Scheibenbogen et al Abstract Background: Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) is an...

Abstract Context Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) is a severe chronic illness which reduces the quality of life. A potential role of neuroendocrine autoimmune dysfunction has been hypothesized. Objective To investigate the occurrence of anti-pituitary (APA) and...

Autoantibody helps with Long Covid The German article https://www.fau.de/2021/07/news/medikament-gegen-autoantikoerper-hilft-bei-long-covid/ The paper is most interesting because of microcirculation, plus the use of BC 007, originally a heart related drug, as a treatment...

Nature - molecular psychiatry Chronic post-COVID-19 syndrome and chronic fatigue syndrome: Is there a role for extracorporeal apheresis? - Bornstein et al Abstract As millions of patients have been infected by SARS-CoV-2 virus a vast number of individuals complain about continuing...

I personally believe that ME/CFS is antibody driven and I therefore think this breakthrough technology could tell us alot about at least a subset of patients. Here you can identify antibodies to extracelluar proteins (non tissue degenerating) which relates to us as patients since there is no...

Touches on ME/CFS

Abstract Impairment of health after overcoming the acute phase of COVID-19 is being observed more and more frequently. Here different symptoms of neurological and/or cardiological origin have been reported. With symptoms, which are very similar to the ones reported but are not caused by...
