Super-resolution spatiotemporal analysis of CXCR4/ACKR3 signalling nanodomains

Early stage researcher 6 (ESR6) project
Supervision: Prof. Dr. Martin Lohse, Dr. Paolo Annibale, Dr. Andreas Bock 
Host: Max Delbrück Center for Molecular Medicine in der Helmholtz Association, Berlin, Germany

I- Project proposal:

Aim:
We aim for an analysis of where, when, and how fast receptors become activated. We will use most advanced microscopy and cell biology techniques to generate images and films of how these processes happen.

Methodology:
Photo-switching of receptor FRET-sensors, analysis of activation kinetics and signal propagation of CXCR4/ACKR3 with sub-millisecond resolution. Analysis of receptor activation and signal compartmentation with super-resolution microscopy and fluctuation analysis. Mapping of CXCR4/ACKR3 signalling nanodomains with receptor/sensor fusion constructs

Planned secondments:

Vrije Universiteit Amsterdam – characterization of CXCR4/ACKR3 photo-switchable ligands

University of Nottingham  – superresolution imaging of CXCR4-and ACKR3 and their signals

 

II – Requirement candidate:

Required diploma: Master in natural or life sciences

Required expertise: Cell culture, molecular cloning, basic pharmacology

Recommended expertise: Fluorescence microscopy, knowledge of receptor pharmacology, quantitative thinking

The transatlantic ECI GPCR symposium #ECIGPCR is about to start, we are ready!! Thanks to the organizers for their excellent job gathering almost 500 people across the globe! @cyclic_Andreas @NicoleAPerry1 @BenderSci @DesislavaNeshe1

My project will be focused on the role of #CXCR4/ACKR3/GRK2 -governed networks in cancer cell migration and metastasis.

Hello 🙂
I am here to continue the series in which all #ESRs are presenting themselves. I am Viviana Marolda and I am in my first year of PhD. I am #ESR13, originally from Italy, and currently, I am working as a PhD student in @CBMSO_CSIC_UAM, at Universidad Autonoma de Madrid.

Hey twitter!
I am @DehanComez. I am taking over the Oncornet account for a while to start a series of all #ESRs writing about themselves and their projects. I am #ESR5, originally from Turkey and right now I am working as a PhD student in @COMPARE_UoBUoN , @UniofNottingham , UK.

New review on #gpcr structural dynamics out in COSB. Great teamwork with the @JanaSelent group. Thanks to @Lundbeckfonden and @novonordiskfond https://lnkd.in/eyjrA5V

ONCORNET2.0 is the successor to #ONCORNET. You can see some of the work of ESRs from the first ONCORNET in this special issue of @MolPharmJournal from 2019, with reviews on #CXCR4 and #ACKR3 structure and function: https://molpharm.aspetjournals.org/content/96/6

Hi everyone – we’re on Twitter! ONCORNET2.0 is a #MarieCurie ITN of 16 ESRs across Europe studying #chemokine #GPCRs #CXCR4 and #ACKR3 in cancer. Our projects cover molecular dynamics, medchem, #pharmacology through to translational work. Follow us for updates from our ESRs!

Hi everyone!

Public service announcement: our Marie-Curie ITN @ONCORNET1 is on Twitter! The 16 wonderful #ECRs working on the project will soon be Tweeting about #GPCR #chemokine #ECR life and #pharmacology

Please #RT & consider a follow or follow back! 🙏😀
