The rules that instruct these divergent outcomes are still unknown. The aim of this CRC is therefore to understand the biology of the multicellular ...

Erythropoietin (EPO) is a cytokine that serves, independent of hematopoiesis, signalling functions within the brain, where EPO and its receptor are upregulated upon injury. The underlying mechanisms, however, have remained obscure. We aim to understand the roles of EPO/EPOR signalling as checkpoints of brain homeostasis and thereby specifically predict effects of recombinant EPO as a neuroprotective drug. To this end, we will explore the induction/expression of EPO and EPOR at the single cell ...

The incidence of Alzheimer’s disease (AD), the leading cause of dementia, increases rapidly with age, but why age constitutes the main risk factor is still poorly understood. Brain ageing affects oligodendrocytes and the structural integrity of myelin sheaths1, the latter of which is associated with secondary neuroinflammation2,3. As oligodendrocytes support axonal energy metabolism and neuronal health4,5,6,7, we hypothesized that loss of myelin integrity could be an upstream risk factor for ...
