Abstract: NF-κB activation by SARS-CoV-2 spike protein and epigenetic age acceleration

This abstract proposes that the SARS-CoV-2 spike protein activates NF-κB, which the authors link to epigenetic age acceleration, inflammaging and senescence; it is a proposed mechanism, not a demonstrated human lifespan effect. [1]

Automatic summary · not editorially reviewed

The key findings

  1. The abstract defines epigenetic age acceleration as an epigenetic clock showing a higher age than the birth certificate, and says it is associated with neurological and other diseases. [1]

  2. Citing Medline-indexed studies, the abstract associates SARS-CoV-2 infection, COVID-19 and long COVID with epigenetic age acceleration. [1]

  3. The authors propose that the spike protein activates NF-κB via Toll-like receptor 2 and MyD88, and that NF-κB mediates epigenetic age acceleration. [1]

Epigenetic age acceleration linked to SARS-CoV-2 in cited studies

The abstract defines epigenetic age acceleration (EAA) as the difference when an epigenetic clock shows a higher age than the birth certificate. It states that EAA is associated with neurological disease and many other diseases. It reports that a series of studies indexed in Medline associate SARS-CoV-2 infection, COVID-19 and long COVID with EAA. These are described as associations, not proven causes.

Proposed NF-κB pathway via spike protein S2 subunit

The authors describe the spike protein S2 subunit as the main mechanism by which SARS-CoV-2 causes pathogenesis. Through Toll-like receptor 2 and a MyD88-mediated response, the spike protein activates NF-κB via the canonical pathway, which starts the pro-inflammatory response. NF-κB in turn is said to mediate EAA. The paper says it investigates the role of NF-κB activation in causing and promoting EAA, and points to long non-coding RNAs that regulate NF-κB.

Methylome, nucleosome and vaccine claims remain proposed

The abstract states that SARS-CoV-2 infection causes methylation and demethylation changes in DNA and telomere attrition, which it associates with COVID-19 severity. It says nucleosome alterations can occur not only with COVID-19 but also after mRNA vaccines coding for the spike protein, which it calls post COVID vaccine syndrome. It further claims that vaccine mRNAs and transcribed spike protein persist over time, promoting chronic NF-κB activation. These are the authors' proposals in an abstract; the full text was not reviewed.

How to interpret this

This is an abstract; the full text was not reviewed. The described links between the spike protein, NF-κB, epigenetic age acceleration and senescence are proposed mechanisms and associations, not demonstrated causes or human lifespan effects.

Based on the study abstract; the full paper, tables and supplementary data were not reviewed.
