Regulation of odorant receptor choice

Objectif

Within most olfactory systems, each neuron chooses to express only one specific odorant receptor out of a vast number of receptor genes. Understanding this complex process will lead to an increased knowledge not only on how the olfactory system is generated, but also provide a deeper insight into how cellular diversity is established in the human brain.

The main objectives of this proposal are to genetically and molecularly address:
- How is odorant receptor choice regulated at a transcriptional level?
- What are the factors, DNA-sites and regulatory processes involved?

The strategies for answering these questions are:
- To identify molecules that specify odorant receptor choice, a work which we have initiated using a novel transgenic RNAi screen in Drosophila. The initial screen has identified 212 candidate genes that effect odorant receptor expression.
- To perform an extensive phenotypic characterization followed by a more detailed analysis of a few selected genes, with the aim of further addressing specifically the molecular genetic interactions between the identified regulators.
- To explore how conserved these novel findings might be.

To this end, I plan to conduct parallel studies in vertebrate systems, using my previous acquired expertise in the mouse olfactory system. The proposed project will be beneficial at multiple levels:
- It will link multiple aspects of development that have been unconnected in the drosophila olfactory community.
- It will reveal novel genes and generate novel tools for addressing questions in other fields: epigenetics, cell signalling, stem cell research etc.
- It will strengthen both the olfactory and cell fate research fields in Europe.
- It will increase the scientific collaboration within Europe.
