Mast Cells/Tregs: The Hidden Causes of Every Chronic Illness

Mast cells and Tregs are cause of every chronic illness If you’re living with a chronic illness like arthritis, asthma, MCAS, or anxiety, the reality is, your immune system is the root cause. Specifically, two little troublemakers are probably to blame: mast cells and Tregs (a.k.a. regulatory T cells). They might be small, but don’t let their size fool you. When these two immune cells are out of whack, they set the stage for almost every symptom you can imagine.

Grab your favorite anti-inflammatory snack because we’re about to go deep into how mast cells and Tregs run the show, why they seem determined to make you miserable, and how they might be at the root of nearly every chronic illness.

Mast Cells and Tregs Explained

Let’s start with our overachievers: the mast cells. These cells are always on the edge of their seat, looking for any sign of danger. This sounds great, but when they’re dysfunctional, they cause autoimmune-like symptoms. It’s like calling the SWAT team because someone might have stepped on your lawn. Normally, this alarm system is helpful, but when mast cells get trigger-happy, they react even when there are NO real threats. This can lead to all-out inflammatory chaos.

And then we have Tregs, the immune system’s “chill out” squad. Think of them as the calm voice telling you to breathe and not overreact. Their job is to keep your immune responses in check, so your body doesn’t become a perpetual battleground. Without enough Tregs, your immune system can go crazy, attacking things like food and even your own tissues.

If you have problems with the mast cells/Tregs, it’s a recipe for chronic inflammation, autoimmune havoc, and a lot of mystery symptoms. Interested in learning more? Let’s dive into how this duo takes center stage in a whole cast of chronic conditions.

Mental Health Disorders Caused by Immune Dysfunction

The immune system doesn’t just stick to skin and joints; it affects your brain. Mast cells and Tregs have both been implicated in anxiety, depression, and even schizophrenia. When they misbehave, they don’t just throw your immune system into turmoil—they mess with your mind.

• Depression and Anxiety: Have you ever felt stressed out of nowhere? That’s the mast cells releasing histamine and inflammatory cytokines as if your brain were a nightclub and it was Ladies’ Night. Research shows that high levels of systemic inflammation (courtesy of our friends, the mast cells) are linked to depressive symptoms and increased anxiety. One study found that people with higher inflammation markers were more likely to feel the blues (1). And Tregs? When they’re low, the brain’s inflammatory responses are like a toddler on a sugar rush—wild, uncontrollable, and erratic.

• Schizophrenia: It’s not just “all in the brain.” Low Treg levels and elevated mast cell activity have been associated with neuroinflammation in schizophrenia. A study found that patients with schizophrenia had reduced Tregs, which led to neuroinflammation (2). So, if you thought your mental health was unrelated to immune health, think again. This connection may explain why many chronic inflammation sufferers experience mental health issues as well.

Autoimmune Diseases: Immune System Gets a Little Overzealous

Autoimmune diseases are like the immune system’s version of getting angry. It’s ready to disagree with anything it sees, even if it’s something reasonable like food or your own tissue. At the heart of this mess? You guessed it: mast cells and Tregs.

• Rheumatoid Arthritis (RA): In RA, mast cells flock to your joints like pigeons to a breadcrumb, releasing inflammatory chemicals that make moving painful. According to a recent study, RA patients have a lot of active mast cells in their joints, causing persistent inflammation (3). And Tregs? Well, they’re on vacation, meaning there’s no one to call off the inflammatory assault.

• Multiple Sclerosis (MS): MS is an autoimmune disorder in which the immune system decides that the nerves’ protective coverings are the enemy. Mast cells hang out in the central nervous system, releasing enzymes that damage nerve cells. A recent study reported that MS patients have fewer functional Tregs, allowing inflammation to run rampant (4). Translation? This lack of immune control worsens MS flare-ups and progression.

• Lupus: This autoimmune condition is the epitome of immune system confusion. Studies show that lupus patients have dysfunctional Tregs, letting inflammation and immune attacks run wild. In a nutshell, lupus flares are caused by mast cell activation and dysfunctional Tregs (5). This causes inflammation, which leads to lupus symptoms.

Allergies and Asthma: Mast Cells On a Mission

If you suffer from allergies or asthma, mast cells are already your sworn enemy. They release histamine at the faintest whiff of pollen, pet dander, or perfume. Tregs are supposed to tell them to calm down, but in people with asthma and allergies, that message doesn’t get through.

• Asthma: In asthma, mast cells gather in your lungs like they’re holding a protest, releasing chemicals that make breathing challenging. In a study on PubMed, it showed that people with asthma have way too many mast cells in their airways, along with less effective Tregs to keep inflammation in check (6). So, each breath becomes a tug-of-war between overzealous mast cells and underachieving Tregs.

• Allergies: If you’re sneezing, itching, or swollen after exposure to something benign, like a cat or a peanut, that’s mast cells in action. A study on PubMed found that people with low Treg levels are more prone to allergies (7). Basically, with no Tregs to say “relax,” mast cells are encouraged to turn any mild exposure into a full-blown allergic reaction.

Cardiovascular Disease: Inflammation Hits the Heart

Heart disease might not seem like an inflammatory condition, but chronic inflammation is a major factor in its development. And who loves inflammation more than the mast cells? No one.

• Atherosclerosis: In atherosclerosis, mast cells infiltrate the artery walls, releasing enzymes that break down arterial walls and destabilize plaque. According to one study, people with high mast cell activity in their arteries are more prone to plaque ruptures, leading to heart attacks (8). And with Tregs out of commission, there’s no stopping this inflammatory parade.

• Heart Failure: Low Treg function has been linked to poor outcomes in heart failure patients. In other words, without Tregs, the heart can’t handle inflammation. A study in Frontiers showed that people with poor Treg function have more severe heart disease, thanks to the immune system’s refusal to quit (9).

Gut Troubles: IBS, Crohn’s, and Ulcerative Colitis

The gut is prime real estate for immune activity, and mast cells and Tregs love to set up shop there. In conditions like irritable bowel syndrome (IBS), Crohn’s disease, and ulcerative colitis, once again, the mast cells/Tregs are the main cause.

• Irritable Bowel Syndrome (IBS): People with IBS have gut linings packed with mast cells releasing inflammatory mediators, which correlates with pain and bloating. A study on Pub Med found that mast cell levels are significantly higher in people with IBS, linking them to those oh-so-fun symptoms (10). As for Tregs, they’re MIA, so there’s nothing to stop the cycle of pain.

• Crohn’s Disease and Ulcerative Colitis: Both Crohn’s and UC are inflammatory bowel diseases where mast cells are hyperactive, triggering constant gut inflammation. A study on Science Direct revealed that low Treg function in these patients allows inflammation to rage on, which explains those dreaded flare-ups (11).

Skin Conditions: Eczema and Psoriasis

You can thank your immune system if your skin is staging a rebellion. Conditions like eczema and psoriasis are linked to both mast cells and Tregs doing what they do best, causing trouble.

• Eczema: In eczema, mast cells release histamine in response to irritants, leading to itchy, red skin. A study on PubMed showed that people with eczema often have tons of mast cells in affected skin areas (12). Also, they have been found to have low Treg function, which means the immune system’s “calm down” button is broken.

• Psoriasis: This one’s like eczema on steroids, with immune cells attacking skin cells at full force. A study found that psoriasis patients have faulty Tregs, which fail to keep inflammation in check and lead to classic scaly patches (13).

Cancer: Product of Chronic Inflammation

Chronic inflammation is a strong risk factor for the development of cancer, and mast cells and Tregs play a twisted role here, sometimes even helping tumors grow and survive.

• Tumor Growth: When mast cells hang out around tumors, they don’t just sit quietly—they release growth factors that help tumors develop their own blood supply. It’s like giving a bully extra lunch money. Research found that mast cells release angiogenic factors, which allow tumors to create their own life support (14). Meanwhile, Tregs can become traitors in the tumor environment, suppressing immune responses that would otherwise attack the cancer cells. Another study showed that Tregs in the tumor microenvironment prevent the immune system from mounting proper anti-tumor responses (15).

Conclusion: A Tug-of-War Between Mast Cells, Tregs, and Your Health

From mental health struggles to heart disease, allergies, digestive disorders, and even cancer, it’s becoming crystal clear that mast cells and Tregs have a MAJOR impact on chronic health conditions. When balanced, they’re our body’s protectors. When out of whack, they’re a mischievous duo capable of creating endless inflammation, confusion, and pain.

If your immune system were an orchestra, mast cells would be the drummer going wild at every minor cue, while Tregs are supposed to be the conductor keeping it all in sync. But when Tregs are not paying attention, the mast cells have free rein to cause inflammatory chaos.

The good news is, that by targeting the mast cells and Tregs, you can make significant progress with chronic illnesses. In my experience, this is the most important correlation to make. Before understanding this, I was a victim of my symptoms. After, I now understand what is causing them, and what to do about it. This is how I help ALL of my clients who have chronic illnesses, and it is what makes my approach different from everyone else.
