Analysis of biased signalling responses through CXCR4 and CXCR7

Early stage researcher 9 (ESR9) project – Davide Capoferri
Supervision: Prof G Milligan, Prof G Graham.
Host: UGL (UK) – University of Glasgow, Institutes of i) Molecular Cell and Systems Biology and ii) Infection, Immunity and Inflammation.

I- Project proposal:

1. To determine the impact of β-arrestin/G protein deficiency on CXCR4/ CXCR7, or heteromer function and signalling.

2. To analyze the efficacy of CXCR4 and CXCR7 modulators in G protein and β-arrestin-dependent pathways using label free technologies.

This project will capitalise on the availability, to our group, of a unique cellular resource allowing for conditional, and selective, expression of β-arrestin proteins in HEK cells. These cells will be transfected with CXCR4 and/or CXCR7 and signalling output and hetero/homodimeristion assessed in the presence, or absence, of arrestin expression. Receptor dimerisation will be examined (in the presence or absence of arrestin expression) using FRET-based approaches. These cells will also be used to test the effects of co-expression of CXCR4 and CXCR7 on directional cellular migration using time-lapse migration assays and, again, the dependence of these effects on arrestin signalling will be investigated. If time permits, we will also use these approaches to analyse the β-arrestin dependency of signalling and function in other members of the Atypical Chemokine receptor family. Planned secondments: UAM (ES), Cisbio (FR).


II- Requirement candidate:

Required diploma: MSc degree in a relevant biological science. Candidates with degrees in biochemistry or pharmacology are particularly encouraged to apply.

Required expertise: Biochemistry, molecular biology, cell culture.

Recommended expertise: Chemokine biology, GPCR biochemistry, protein chemistry.

Great way to finish the week off with some #FCS measurements of CXCR4-expressing HEK cells at @UoNLifeSci 🔬 #FluorescenceFriday

Hello everyone!
I am Noemi Karsai and I’m the next in our #ESR introduction series. I’m #ESR11 and I’m originally from Hungary, currently doing my PhD at @UoNLifeSci @COMPARE_UoBUoN, UK.

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

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

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:

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!
