NCT06259500

Brief Summary

Experimental and genetic data, as well as brain imaging, support a role of the hypothalamic Arcuate nucleus neurons and their communication with surrounding microglia in anorectic conditions, but it has until recently not been possible to explore these cells at a molecular level in anorexia nervosa (AN) patients. This attributed to the obvious lack of valid tissue and non-invasive imaging techniques of high enough resolution. Stem cell models have evolved as a useful tool for the exploration of other neuropsychiatric disorders with a comparably high genetic contribution as AN. The investigators will here use patient-derived induced pluripotent stem cells (iPSCs) to profile Arc neurons and peripheral blood mononuclear cell (PBMC) derived microglia in AN, thus defining molecules to explore as drug targets.
