This work will be performed in the Cellular Communication and Neurodegeneration group led by Prof. Lies De Groef in the Animal Physiology and Neurobiology Division of the Biology Department. Our research focuses on the fundamental understanding of mechanisms of neurodegeneration in the central nervous system. “The eye as a window to the brain” is the central theme of our research. We focus on the inter-relatedness of neurobiology and ophthalmology and exploit this cross-over of disciplines to enrich fundamental research into central nervous system function. A greater understanding of the cellular and molecular mechanisms governing brain function are key to unlock novel therapeutic strategies for central nervous system diseases – which represent a rising burden –, and the visual system offers unique possibilities to tackle these research questions. Prof. De Groef and her team have more than 10 years of experience/expertise in neurodegeneration and -inflammation research in the visual system, in vivo retinal imaging, electrophysiology and visual behavior testing, and disease mechanisms of glaucoma, Parkinson’s and Alzheimer’s disease. You will work in close collaboration with our partners from the Leuven Brain Institute, KU Leuven and UZ Leuven.

Emerging evidence suggests that extracellular vesicles (EVs) and their miRNA content may function as master regulators of the cellular state of neurons and glia in the central nervous system. Given that miRNAs serve as regulatory nodes with an integrated effect on multiple gene networks, their impact on cellular function is important and the consequences of their dysregulation may be severe. In this project we focus on the role of EV-miRNAs in the signaling between ganglion cells and glia in the retina. The goal is to better understand how EVs and their miRNA cargo mediate intercellular signaling between ganglion cells and glia, and how the dysregulation of this neuron-glia communication leads to loss of homeostasis, glial reactivity and neurodegeneration. With this research, we aim to gain a better understanding of the fundamental biological processes that play a role in intercellular communication in the central nervous system. Via a systems biology approach –comprising miRNA transcriptomics, mRNA transcriptomics and proteomics studies– and functional studies of selected EV-miRNA targets, we aim to identify direct target genes, pathways and biological functions regulated by EV-miRNAs in the retina. Furthermore, this research may also deliver a first proof-of-concept for the manipulation of EV-miRNAs as a strategy to modulate neuron-glia communication and thereby prevent glial reactivity and neurodegeneration.
