Simple Summary​

This review examines the role of heat shock protein 60 (Hsp60) in COVID-19, highlighting its impact on immune modulation, inflammation, and endothelial dysfunction. Hsp60, a chaperone protein essential for protein folding and protection against cell stress, has been linked to COVID-19 pathogenesis through its interactions with the immune system and potential involvement in post-infectious autoimmune processes.
One of the key aspects discussed is the phenomenon of molecular mimicry, wherein Hsp60 exhibits epitope similarity with a number of SARS-CoV-2 proteins, a circumstance that may potentially culminate in the induction of autoimmune responses.
This mimicry has the potential to contribute to the development of autoimmune conditions, including Guillain–Barré syndrome and autoimmune thyroiditis, in patients infected with SARS-CoV-2.
The document discusses Hsp60’s role in endothelial damage and thromboembolic complications, suggesting it could serve as a biomarker for disease severity and a therapeutic target.
It raises concerns about vaccine safety due to Hsp60’s structural similarity to SARS-CoV-2 proteins, which may trigger autoimmune responses.
The potential for Hsp60 to generate anti-tumor immunity is explored, indicating that immune responses to SARS-CoV-2 might also target tumor cells with similar epitopes.
Further research is necessary to understand Hsp60’s role in disease fully and to develop effective therapeutic strategies.

Abstract​

Heat shock protein 60 (Hsp60) plays a crucial role in cellular homeostasis and stress responses. Recent evidence highlights its involvement in COVID-19 pathophysiology, particularly in immune modulation, inflammation, and endothelial dysfunction.
Extracellular Hsp60 can interact with Toll-like receptors, amplifying inflammatory responses and contributing to cytokine storm and tissue damage.
Additionally, since the presence of several common epitopes with SARS-CoV-2 proteins, its role in molecular mimicry suggests a potential link also to post-infectious autoimmune disorders.
Hsp60 has also been implicated in endothelial damage and thromboembolic complications observed in severe COVID-19 cases.
Beyond its pathogenic roles, Hsp60 could emerge as a potential biomarker for disease severity as well as a target for therapeutic strategies aimed at modulating immune responses.
Finally, the structural similarity with SARS-CoV-2 proteins raises important considerations regarding both vaccine safety and the unexpected potential for anti-tumor immunity.
This review critically examines the multifaceted roles of Hsp60 in COVID-19, specifically from a morpho-functional point of view, highlighting its implications in disease progression, post-viral complications, and therapeutic opportunities.

​

A brief interlude on HSP60 and the role of this protein in the context of SARS-CoV-2.​

​

We had already worked our way far enough into this that we had a rough understanding of the mechanism of this heat shock protein and had connected the dots regarding the consequences for the endothelium and the immune system.​

​

1/​

HSP60 and SARS-CoV-2: Les Liaisons Dangereuses​

​

​

This study now takes the next logical step and has found that SARS-CoV-2, like TB mentioned earlier, also carries this protein—which is likewise present in the human body.​

​

Unfortunately, that is also where it stops, just before things get really interesting.​

​

2/​

If you take the line of reasoning to its logical conclusion, one suspicion inevitably presents itself: perhaps those who develop a severe course of disease have previously, at some point, come into contact with another HSP60-bearing infection, meaning that their immune system is not merely going to war against coronavirus...​

​

3/​

...but is experiencing a flashback to a contained infection from the 1990s and, in a state of maximum alarm, firing on all cylinders.​

​

Another possibility would be that these “sleepers” are actually still present somewhere intracellularly or embedded within connective tissue in a remodeled form, and that the immune system’s engagement with COVID (or a vaccination) allows them to become active again.​

​

4/​

And last but not least, I consider it conceivable as a third scenario that this flashback, together with COVID—and perhaps even reactivation of the “sleepers”—becomes so completely self-perpetuating that the immune system can no longer distinguish friend from foe and reaches the next level:​

​

5/​

Mistaking itself for the enemy.​

​

Particularly fatal in this context:​

​

HSP60 is also found in the skin and in hair follicles—in the form of human mitochondrial HSP60 (HSPD1).​

​

In all of us. Regardless of whether we are healthy or ill.​

​

6/​

As an aside, this was actually my entry point into this rabbit hole, because I have been observing for ages that my infection-like symptoms, shortness of breath, light-headedness, dizziness, etc. always improve slightly for a brief period whenever the bed has been freshly changed or I have just put on a fresh pair of pajamas.​

​

The longer that does not happen, the more I deteriorate. Heart palpitations and all the rest of the fun included.​

​

7/​

So there had to be something “coming out of me” that was fueling this inflammatory and immune cascade.​

​

There weren't many possibilities:​

​

Active pathogens? Toxins released through sweat and aerosols? Antigens somehow making their way out?​

​

None of that made much sense.​

​

8/​

Especially because the effect is so incredibly rapid and so consistently reproducible that there simply cannot be all that much going on during that short window.​

​

The solution to the mystery was:​

​

Socks.​

​

Socks and a hat.​

​

9/​

A few weeks ago, despite it being the height of summer, I was extremely cold, so I put on long cotton knee-high socks and a thin cotton hat.​

​

I changed nothing else.​

​

And presto— I felt just a tiny bit better.​

​

Sounds crazy?​

​

That's what I thought, too, so I tried it back and forth dozens of times.​

​

Always the same effect.​

​

10/​

But since I have neither head lice nor athlete’s foot, it had to be something more subtle.​

​

And something that could be inhaled, or at least reach the mucous membranes in the nose and mouth.​

​

Because if the substance in question were absorbed through the skin, socks and a hat would not have had any shielding effect. ☝​

​

11/​

The rest is history.​

​

I interrogated the AI and asked which molecules, fragments, or substances can be found on the surface of human skin and on hair—whether excreted through sweat or shed through abrasion—that also occur in similar forms in the “sleeper pathogens” I was looking for, and that the immune system might all too readily mistake for one another.​

​

12/​

And here we are.​

​

End of story (for now).​

​

Everything else can be found in yesterday’s thread.​

I find it hard to credit that any human being can drag together as many long-dead memes as this. Maybe this is the impact of AI? HSP60 was trendy as a molecular mimic in the 1980s. A decade of research projects yielded nothing whatever.
