Project description:

Title:
Neuro-vascular communication in the central nervous system
Summary:
The central nervous system (CNS) (brain and spinal cord) is composed of different neural cell types organized in a very stereotyped pattern and localized in defined compartments. Apart of the neuronal cell types, the CNS is also composed of blood vessels, responsible for providing oxygen and nutrients to the neuronal tissue. Similar to neurons, during development, blood vessels also follow defined pathways to enter and invade the CNS in order to assure proper oxygen and nutrient delivery to all parts of the tissue.

We recently found that the typical angiogenic factor Vascular Endothelial Growth Factor (VEGF) is important for vessel growth into the developing central nervous system. However, neurons regulate VEGF availability by expression a VEGF trapping receptor and like that making sure that blood vessels follow a stereotypic patterning of vascularization (Himmels et al.Nat Commun 2017). We could also show that that VEGF regulates angiogenesis by the activation of the Hippo pathway effectors YAP/TAZ (Wang et al. Dev Cell 2017).

Based on those results, in this project we will further aim to understand how different neuronal populations control CNS vascularization and identify the molecular mechanisms of this regulation.
