How's that lymph system doing.
Blastic NK-cell lymphoma, England. Image
Blastic NK-cell lymphoma means something has gone *really wrong* in immune regulation.
It’s a malignancy of the cells that are *supposed to destroy infected cells*.
NK cells - "natural killer” cells - are the immune system's first-strike unit.
They're the ones that find and kill virus-infected cells before antibodies even show up.
If you start seeing more NK-cell cancers, something’s driving chronic activation and mutation inside that system.

Something up here. Image
Now, think about Covid infection:
Every infection triggers a massive NK-cell surge.
Those cells get overstimulated, exhausted, and sometimes permanently altered.
Post-COVID studies show lingering activation markers, basically, NK cells stuck in attack mode for months.
That means they keep dividing...
Keep generating oxidative stress...
Keep collecting DNA damage in a high-inflammation environment...
And all that while the repair pathways (like p53) are being suppressed (by cytokines like IL-6 and TNF-alpha).
At the same time, the immune brakes are off.
T cells are depleted and exhausted.
Interferon signalling is blunted.
So when an abnormal clone of NK cells appears, the immune system doesn't clear it. *It lets it grow*.
Add to that the reactivation of latent viruses (EBV, CMV, HHV-6) all known to cause NK/T-cell malignancies...
COVID reawakens them, repeatedly.
Each reactivation wave means another round of inflammation and oxidative stress and immune dysregulation.
The problems aren't just in adults... there's stuff going on in kids too. Image
So you end up with this:
A system of immune cells pushed to divide too often,
mutating in an inflamed environment,
with the tumour-suppressor side of immunity switched off.
And from that, you get what we’re seeing here. A surge in blastic NK-cell lymphoma.
I wonder what else is going on in that lymph system...

Oh boy.
😮 Image
Oh boy. Image
Oh boy oh boy Image
Erm.
👀 Image
👀 Image
👀 Image
👀 Image
And then strange things going on with other aspects of the immune system... Image
And this running away... Image
And then damage to all that lets this kind of damage loose... Image
And that this... Image
Hmm.
Those gut infections are really exploiting something these last four years, aren't they... Image
Oh my word. Image
👀 Image
This is all just nuts. Image
This damage is in adults, kids, infants, everywhere. Image
It's in these kind of diseases where the end result is scarring of internal organs after immune hyperactivation:

This is in KIDS AGED 0 to 9. Image
You might expect this to pop up as a result of immune dysregulation in the gut... Image
Oh boy. Image
What the what. Image
What does inflammation in the brain cause... Image
More tomorrow... this list is long.
Maybe a few more... Image
👀 Image
👀 Image
This is in *kids*
👀 Image
This is in *young adults* 👀 Image
flip. Image
Nothing to see here, just a doubling of TUBERCULOSIS OF BONE. Image
Oh dear. Image
Hmm.
I didn't expect so many people to read this thread, or I would have included a bit like this, explaining that not every condition is rising like that...

I think one of the most important conclusions people are missing from the data in the recent big studies is that covid infections cause radically diverse long term effects in different age groups.
So much so that it could appear as if they've been infected with different viruses.
But it's not the virus that's different, it's the immune system, the metabolism, and the way the body repairs the damage done by the infection.

Okay folks, I'm calling it, and it's bad news:

The word mucinous is going to become much more common.

Yes, bookmark this tweet, it looks bland, but it's important.
oh, okay. I won't leave you hanging.

I've written a lot recently about how we're missing the big picture of how covid infection is doing cumulative damage to interfaces in the body - linings, membranes, barriers, walls, filters.
I don't want to rewrite that all here, but I don't want to bust the flow of this thread, so at the end of it, I'll post the thread I wrote on linings.

I know, I know, you're going to laugh at me for saying that you're more likely to have problems with cramp after you've had a covid infection, but it's all very simple science.
Loads of people have been mentioning cramp recently, and like so many other conditions, yes, covid infection makes it more likely, and makes it worse.
It's just an extra factor on top of all the normal factors for cramp.
Muscles are fussy about blood flow.
They need a steady supply of oxygen to contract and, crucially, to relax.
Covid messes with the small blood vessels that supply it, so muscles end up slightly under-fuelled, and under-fuelled muscles cramp.

Do you know which whacky loons say that covid infections increase the risk of heart disease?
The British Heart Foundation.
Do you know which antivaxers say that covid vaccines do not fully protect against infection, illness, or long term effects?
Pfizer.
Do you know which hysterical doom merchants say covid can cause long term lung damage even after a mild case?
British Lung Foundation.

The three subtle warning signs that everyone's missing:
1
All of the people asking "why is everyone sick all the time now?"
2
All of the people who have been constantly sick for the last year.

A couple of very important studies out just in the last 24 hours confirming what we've been saying for years and years now: Covid infections affect your immune system *badly*.
Here's a few things you may have missed in them. Image
This is almost entirely post vaccination data
This is not an unprotected population.
Baseline immune measurements come from a period when vaccination coverage was already high, and the immune damage appears *after mass infection*.
So two things there:
The effect didn't appear until after infection.

Vaccination didn't stop it.
