Project description
Brain organoids for studying stress responses and mental illness
When an individual encounters a stressful situation, the stress hormone system is activated to initiate a cascade of hormonal and physiological responses that involve cortisol among others. Chronic or prolonged exposure to stress can deregulate the stress hormone system and may lead to mental illness. Funded by the Marie Skłodowska-Curie Actions programme, the PrenatalStressOmics project is interested in studying the molecular mechanisms involved in stress-related mental illnesses. Researchers propose to develop 3D cerebral organoids that mimic the human brain as models of mental illness in the prenatal period. They will analyse transcriptomic and epigenetic changes in response to stress, aiming to delineate the molecular basis of human vulnerability and stress response.
Objective
Mental illnesses affect 25% of the EU population and share increased disease risk through long-term changes to the stress hormone system. These are precipitated as adversities during early life, including the prenatal period. Given the role of stress in causing mental illnesses, it is imperative to learn more about the molecular mechanisms involved. Some progress has been made in elucidating the neurobiology of stress, but many questions cannot be addressed with current tools, which include animal models and 2-dimensional human cell culture systems. This proposal aims to establish 3-dimensional culture systems called cerebral organoids – stem-cell-derived tissues that recapitulate features of the human brain – as research models for developmental psychiatric disturbances. We will focus on glucocorticoids (GCs), some of the primary mediators of stress exposure on the organism, and use organoids as a model of early developing brain. Molecular mechanisms will be compared between ‘stressed’ and ‘unstressed’ conditions, by sequencing the transcriptomes of individual cells. Furthermore, since stress-related disorders are mediated through epigenetic mechanisms, the impact of elevated GC exposure on specific cell types in the cerebral organoid model will be quantified at the epigenome level. These novel and powerful techniques will allow us to deconstruct tissue heterogeneity, elucidating the fine molecular underpinnings of human vulnerability and response to stress. Comparing findings to evidence from longitudinal human cohorts of mothers and their babies who underwent stress during pregnancy will allow placement of findings into the clinical context. This research would pave the way for translation into clinical research, and expedite transitions from basic research to identification of at-risk populations, and even intervention strategies.
