MOODSTRATIFICATION - Combining immunology and psychiatry
Based on former research in the field of immuno- psychiatry we assume that at least part of the major mood disorders are the result of a systemic abnormal condition of imbalances in the T cell system and a proneness to inflammation. T cells play an important role in our immune responses to specific antigens. A vulnerable immune condition may also lead to various autoimmune diseases (such as Hashimoto’s thyroiditis – which is more frequent in patients with major mood disorders).
The consortium MOODSTRATIFICATION is coordinated by ErasmusMC and brings together 12 partners from 7 countries: psychiatrists, immunologists, epidemiologists and pharmaceutical industry. This multidisciplinary European research team is working on new ways of diagnosing and treating patients with a major depressive episode on the basis of monocyte, lymphocyte and cytokine immune profiles.
The hypothesis of our project is that a large proportion of severe mood disorders are the result of deviant immune reactions, caused by one or a combination of the following issues:
- (Inborn and acquired) T cell imbalances which result in
- mal development and malfunctioning of the brain, and
- flares of chronic inflammation, further impacting brain functioning;
- Childhood trauma leading to an even higher inflammatory state of the immune system.
We reflect on our hypothesis in more detail on the following page on our project website: immune neurological model
The aim of MOODSTRATIFICATION is not only to refine the hypotheses above, but also to develop simple blood tests to measure the above mentioned immune imbalances in clinical practice. As a follow up on the immune signatures found, various therapy trials will take place with T cell enforcing and anti-inflammatory treatments on patients with mood disorders and T cell imbalances.
MOODSTRATIFICATION has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 754740
