The Cortene Way and CFS/M.E.

Research into CFS/M.E. is very complex, there are multiple possible starting points and these can branch into a multitude of subsets. There is clear definition of the immune/neurological and endocrine pathways and the question is what came first. It is known that the immune system will trip the neurological pathways and vice versa. Stress is very harmful and is known to trigger a number of pathways.

The  HPA (hypothalamus/pitituary/adrenal) pathways are known to be defective and the following study looks at the possibilites. Here is an excerpt:

Stress

“Stress” is an unfortunate term. Usually we think of stress as emotional; in biology, though, stress means any threat that disrupts the balance (or homeostasis) of the body. The stress response or HPA axis, prepares the body to respond to the threat. Any threat then, whether infectious, emotional, physical, chemical, etc, will initiate the stress response.
Once triggered, the stress response suppresses non-critical functions such as growth and metabolism (i.e., hypothyroidism, long linked to ME/CFS) and reproduction (i.e., hypogonadism, also connected with ME/CFS). It also releases cortisol to make sure the brain, heart and muscles have sufficient glucose (at the expense of less critical functions like digestion). Cortisol also primes the immune system for action (and has a delayed proinflammatory effect).
As noted in Part 1, studies indicate that chronic stress causes a progression from high to low cortisol and can result in the development of cortisol sensitivity – a situation in which the body becomes more responsive to cortisol. (When cortisol sensitivity occurs low cortisol can have the same or greater effects than high cortisol does in healthy individuals.) This increased cortisol sensitivity cannot be measured by cortisol/synacthen tests (which measure level not effect) but it does results from epigenetic changes that can be shown.
question mark
Cortene’s new hypothesis for ME/CFS will shortly be tested in a small exploratory drug trial
Studies indicate that ME/CFS patients show the same alterations in cortisol levels and cortisol sensitivity seen in chronic stress. These findings help to explain the overlap of immune and metabolic symptoms found in ME/CFS and chronic stress but they do not explain the neurological issues found in ME/CFS.
The stress response also involves brain neurotransmitters such as serotonin, norepinephrine, dopamine and GABA (gamma-aminobutyric acid), which focus on and deal with the stress in a stressor-specificway. These neurotransmitters – which may have been under-appreciated in ME/CFS research – are at the core of Pereira’s hypothesis.
Animal studies indicate that short, medium and long term responses to stress are governed by two factors, CRF (corticotropin-releasing factor) and UCN1, that affect the release of serotonin (and norepinephrine) in the brain and cortisol (and epinephrine) from the adrenal glands.

Patrick Gut Environment

\ Keywords to use in further research, GALT, tight junction proteins, Mucin layer, microbiome in MECFS or Long Covid, Goblet cells.   It was great chatting with you the other day. I’ve put together this general overview, but as I mentioned, you’ll definitely want to do your own deeper research. This is a very complex, interactive environment, and you’ll naturally come across many different opinions about what’s happening. Most opinions tend to focus on single layers, but as I’ve discovered, these layers are highly interconnected and influence one another. I don’t want to oversimplify things, nor do I want to overcomplicate them. It takes time to truly understand the gut environment in its proper context. I’m also cautious about saying “do X and you’ll get Y,” because results are rarely that straightforward. When I introduce layered therapies, I look for subtle changes across a list of markers I track. That’s why I believe this should be approached with care and patience—though I’m ...

Gut environment

 OK let's go back over the scenario Somebody gets a gut bug that could be viral or bacterial and we're going to put in the context of either long COVID or MECFS Let's discuss what exactly happens of how the body begins to adapt to this insult p — let’s build this cleanly, structurally, and without drama. This is the core terrain‑mechanics model of what happens when someone gets a gut bug (viral or bacterial) and then develops a long‑tail condition like long COVID or ME/CFS . This is the architecture that explains why the system never fully resets . I’ll walk you through it in chronological order , layer by layer, so you can see exactly how the body adapts — and why those adaptations become the trap. ⭐ 1. The Initial Insult Terrain layer: immune activation, epithelial irritation, redox stress A viral or bacterial gut infection does three things immediately: damages epithelial cells strips mucin spikes inflammatory cytokines This creates: redox collapse increased permeabil...

Paneth Cells - guardians of the intestinal tract

  Click for the AI slideshow: https://sl.bing.net/hBioK3sTdDw From Google Gemini: Paneth Cells: The Guardians of the Gut Paneth cells are specialized epithelial cells found at the base of the intestinal crypts (small invaginations in the intestinal lining). They play a crucial role in maintaining the gut's health by acting as a first line of defense against harmful microorganisms. Key Functions: Antimicrobial Defense: Paneth cells produce and secrete a variety of antimicrobial peptides and proteins, such as lysozyme, defensins, and phospholipase A2. These substances help to kill bacteria, fungi, and other pathogens that may invade the intestinal tract. Regeneration of Intestinal Epithelium: Paneth cells contribute to the maintenance and regeneration of the intestinal lining by supporting the stem cells located nearby. Immune Regulation: These cells participate in regulating the immune response within the gut, helping to balance the body's reaction to both beneficial and ha...
