Offer: PhD student and Postdoc positions
Project Title: Neuro-vascular communication in the central nervous system
Research group: Prof. Dr. Carmen Ruiz de Almodóvar
Application Deadline: 30.06.2022
Start of projects: as soon as possible
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.
In our group, we aim to identify and characterize the molecular mechanisms of the bidirectional communication between neural cells and cells forming the vasculature in development, homeostasis and disease. In disease, the interaction of the vasculature with the immune system will alsobe explored. We intend to understand how different neuronal populations control CNS vascularization and how the vasculature also actively contributes to the development and maintrenance of CNS homeostasis.
