Talk with AI (Claude) to try to understand Crumblecooking’s comment.
Some info to move the Schmilblick forward (to move things along).
Context:
Weak ground: researchers focused on patients diagnosed with either ADRD or mild cognitive impairment (MCI).
A widely used supplement marketed for joint pain relief may be linked to faster progression of Alzheimer's disease, according to new research from the University of Florida.
Researchers found that glucosamine significantly increased the attachment of sugar molecules to proteins within cells. Mice receiving glucosamine also showed worsening deficits in social memory, which is the ability to recognize and remember other individuals.
When scientists chemically reduced this sugar-tagging activity, memory performance improved.
"In the United States, there are about 7 million people living with Alzheimer's and millions more with related dementias such as Lewy body or frontotemporal dementia," said senior author Ramon Sun, Ph.D., director of the Center for Advanced Spatial Biomolecule Research and associate director for innovation of UF's McKnight Brain Institute. "A lot of these people actively take an over-the-counter supplement that could be making their disease progression worse."
Comment from the forumer Crumblecooking:
Add linoleic acid to this—the prostaglandin E₂ precursor—and you then have a powerful yeast➝hyphal transducer—more commonly known as potato chips, bread, and granola bars.
Comment from LucH (me) (not yet posted):
I know we have here a weak ground: already inflamed cells behind BBB by ROS perturb the cohesion, weakening the balance behind BBB: There is inflammation (via ROS) and perturbation in the brain cells as far as the homeostatic balance is concerned:
Detailed explanation:
The blood-brain barrier (BBB) is composed primarily of cerebral microvascular endothelial cells and astrocytes linked by tight junctions (TJs) and adhesion molecules (AMs). This system maintains the homeostatic balance between the brain parenchyma and the extracellular fluid.
=> Not a proof, OK. But more and more studies take this direction...
How to Help a Leaky BBB before it’s too late (usual process for ¾ people above 80ies)
a) Which useful molecules can cross the BBB:
Aspirin (mind the platelet impact)
Caffeine (coffee and tea)
EGCG (green tea)
Resveratrol
Taurine
Vitamin E
Vitamin C
Etc.
See detailed information on reference 2.

Which Supplements Repair the Blood-Brain Barrier?
Several B vitamins support blood-brain barrier health: a vitamin B1 (thiamine) deficiency disrupts the blood-brain barrier, and supplementation can restore it. Vitamins B12, B5, and B9 (folate) can restore the integrity of the blood-brain barrier. (4) Magnesium, as a cofactor in over 300 biochemical processes, affects brain neurotransmitters, enzymes, and hormones. Magnesium L-threonate is often used for its potential brain benefits and may help manage certain brain disorders, such as depression, Alzheimer's disease, and age-related memory loss.

Glutamine et cancer
Un lien intéressant :
https://www.julienvenesson.fr/glutamine-cancer/
A natural compound, EGCG from green tea, also shows promise. It counteracts the action of glutamate dehydrogenase, which converts glutamate into α-ketoglutarate, leading to the death of cancer cells.

Glutamine is the preferred amino acid of cancer cells, required for their growth. But if you try to limit this intake, the cancer will destroy muscle tissue to obtain it. You can try to ration it, but never eliminate it. Therefore, you limit it, you don't eliminate it.
NB: Whenever I suffer from a weak / a thin layer of stomach mucin, I associate ¼ tsp glutamine and ¼ tsp taurine powder (+ 1.5 g magnesium bisglycinate). Take one hour before bedtime. Always associate both to dampen the possible glutamate pathway.
Question for AI (Claude)
I don’t want a comment or an analyze of my answer but I’d like an explanation for Crumblecooking’s comment:
“Add linoleic acid to this—the prostaglandin E₂ precursor—and you then have a powerful yeast➝hyphal transducer—more commonly known as potato chips, bread, and granola bars.”
=> What is the mechanism? Asparagine becoming nitrosamine?
Short answer for IA (summarized because in French and 2 pages A4 long)
No, not linked to nitrosamine.
Vocabulary: the yeast→hyphal morphological transition.
Hyphal: Adjective derived from “hypha”, describing anything related to this filamentous form.
We have a morphological change from the yeast form (isolated round cell) to the invasive filamentous form.
So, ultra-processed foods rich in omega-6 oils potentiate the pro-Alzheimer's effect of glucosamine via a dual mechanism: local inflammation (PGE₂) + fungal dysbiosis, promoting a compromised intestinal mucosa/BBB. The hyphal transition of Candida increases epithelial permeability, exacerbating precisely the leaky BBB problem you describe (LucH talking with Claude).
LucH said:
Okay, I get it. It's a stimulant on already fragile ground.
IA says:
Exactly.
That's the most accurate wording.
A stimulator—not a primary cause—on an already weakened foundation:
• Compromised BBB
• Chronic low-grade inflammation
• Already disrupted O-GlcNAcylation
Glucosamine + PGE₂ don't initiate the disease; they accelerate what's already underway. That's why the study refers to aggravated progression, not a trigger.
This ties in with your notion of a weak ground from the introduction—the underlying condition precedes it, the stimulator amplifies it.
