Autoimmune disease.
When the body loses tolerance.

Immune tolerance is the body’s active ability to protect its own tissues. Regulatory T cells keep self-reactive immune cells in check. Their function is closely linked to mitochondrial function, methylation and other forms of gene regulation. At MediBalans, we investigate which biological and lifestyle factors are relevant to your individual situation.

What does the immune system’s own brake need to function? The 2025 Nobel Prize in Medicine recognised discoveries about immune tolerance. Continuing research reveals concrete mechanisms to investigate, from cellular metabolism to signals produced by gut microbes.

Our role alongside your existing care

An autoimmune diagnosis can leave questions about fatigue, gut symptoms and everyday function even when treatment is underway. We review your situation alongside your existing care, identifying questions that merit further assessment.

We do not replace your rheumatologist, endocrinologist or other treating specialist. Changes to prescribed treatment are coordinated with the treating clinician. Research on immune tolerance helps explain biological mechanisms; it does not show that every mechanism can be measured or corrected in an individual patient.

From mechanism to clinical question

Which factors are relevant to you?

Your diagnosis, disease activity, previous results and medicines are the starting point. We also review gut symptoms, diet, nutritional status, sleep, physical activity and recovery. Lifestyle is central to the individual assessment.

Methylation-related questions are assessed through diet, medicines and relevant laboratory results, such as folate, B12 and homocysteine. Homocysteine is interpreted alongside factors including nutritional status and kidney function. Genetic findings can add information about predisposition when relevant to the clinical question. [8]

Global Constraint Rule · our working model

GCR helps structure questions about possible biological constraints. Your medical history and clinical findings determine which analyses are appropriate and how results should be interpreted.

Nobel Prize in Physiology or Medicine 2025

The body has an active system
for protecting itself from itself.

Mary E. Brunkow, Fred Ramsdell and Shimon Sakaguchi were recognised for discoveries concerning peripheral immune tolerance. Their work showed how regulatory T cells, or Tregs, and the FOXP3 gene help prevent the immune system from attacking the body’s own tissues. [1]

Tolerance must be actively maintained. Treg cells act as a biological brake on other immune cells. FOXP3 controls central aspects of their development and function. When this regulation fails, self-reactive immune responses can gain ground.

This makes the conditions for immune regulation a central research question: how are these cells affected by their metabolism, their environment and the signals they receive?

Research connecting the mechanisms

Mitochondria. Microbiome. Methylation.

Three routes into the same question: what enables Treg cells to maintain tolerance?

01 · Mitochondria · mouse model

Cellular metabolism sustains the brake

When researchers disabled complex III in the mitochondrial respiratory chain of Treg cells, the cells lost their suppressive function and the mice developed severe inflammation. Treg numbers and Foxp3 expression remained intact. This directly connects mitochondrial function to immune regulation. [2]

02 · Microbiome · cell and mouse studies

Gut bacteria signal to the tolerance system

Butyrate, a short-chain fatty acid produced by bacterial fermentation in the gut, increased Treg differentiation in experiments. Changes in histone acetylation at the Foxp3 gene provided a possible molecular explanation. Gut microbes can influence immune regulation through the substances they produce. [3]

03 · Methylation · metabolism and gene regulation

Methylation shapes immune-cell behaviour

Methionine metabolism supplies cells with SAM, a central methyl donor. Methylation of DNA and histones influences gene regulation and immune-cell development. Stable Treg cells also have a characteristically demethylated region of FOXP3. The connection involves both nutrient metabolism and the regulation of specific genes. Explore the connection →

These studies explain biological mechanisms. Demonstrating that a particular treatment restores immune tolerance in people requires clinical studies of that treatment.

Methylation · connecting nutrition, metabolism and immune regulation

Methylation is part of
the immune system’s control machinery.

Immune-cell behaviour is influenced by which genes are active. Methylation metabolism connects nutrient availability to the regulation of those genes, affecting both inflammatory and tolerance-preserving functions.

  1. Folate + B12Participate in recycling homocysteine to methionine.
  2. Methionine → SAMSAM supplies methyl groups for DNA, histones and other molecules.
  3. SAM → SAH → homocysteineAfter methyl transfer, homocysteine can return to the methionine cycle.
A simplified view of the methionine cycle and its connection to folate and B12 metabolism. [5] [8]

Nutrient metabolism can change gene regulation

SAM, S-adenosylmethionine, donates methyl groups to DNA, histones — the proteins around which DNA is wrapped — and other molecules. The transfer produces SAH, S-adenosylhomocysteine. The availability of SAM and SAH influences methylation reactions, connecting cellular metabolism to gene regulation. [5]

In studies of activated T helper cells, methionine availability influenced SAM, histone methylation and inflammatory cell programmes. Methionine restriction reduced disease-driving Th17 responses in a mouse model of autoimmune neuroinflammation. Methylation metabolism can therefore influence how an immune response develops. [6]

The right regulation in the right cells

Demethylation at a specific FOXP3 region is important for stable Treg identity. This makes which genes and which cells are affected central to understanding methylation changes. Methylation does not operate as a single dial where higher is always better. [4]

This is where methylation meets mitochondria. In the Treg complex III study, the metabolites succinate and 2-hydroxyglutarate increased; these inhibit the TET enzymes that demethylate DNA. Altered metabolism coincided with increased DNA methylation and lost suppressive function. The study connects mitochondrial metabolism, epigenetics and immune regulation. [2]

FAQ

Questions about autoimmune investigation

The first 45-minute consultation is free. What the investigation costs after that depends on which tests are medically justified in your case — you get a clear cost picture before anything is ordered. Prices for individual tests and packages are listed under Book.
No. MediBalans is a private clinic in Stockholm and you book yourself, without a referral.
Yes. The consultation can take place at Banérgatan 10 in Stockholm or online. Test kits for home sampling are posted to you wherever you live.
We review your diagnosis, previous findings and treatment alongside gut symptoms, diet, nutritional status and lifestyle. The aim is to identify relevant clinical questions, select appropriate analyses and plan follow-up in coordination with your usual care.
Mary E. Brunkow, Fred Ramsdell and Shimon Sakaguchi were recognised for discoveries concerning peripheral immune tolerance. Their research showed how regulatory T cells and FOXP3 help prevent the immune system from attacking the body’s own tissues.
Yes. In a mouse study, Treg cells lost their suppressive function when mitochondrial complex III was disabled, despite preserved Treg numbers and Foxp3 expression. This is strong evidence for a mechanism in that model. It does not establish mitochondrial dysfunction as the cause in every patient or show that a supplement treats autoimmune disease.
Methylation connects nutrient metabolism to gene regulation. SAM and SAH influence methylation reactions, and studies show that methionine metabolism can change inflammatory T-cell programmes. Stable Treg identity is also linked to demethylation at a specific FOXP3 region. The significance depends on which genes and cells are affected.
No. A stool test, ALCAT, MethylDetox or CMA does not directly measure Treg suppressive function or methylation of the FOXP3 region. These analyses answer other questions and need to be interpreted alongside medical history, clinical findings and established tests.
We follow symptoms, function and the test results relevant to your diagnosis and plan. Changes in autoantibodies alone do not demonstrate restored immune tolerance. Medication changes are coordinated with the treating physician.
