COMING UP: MRC@UCL Centenary Science Fair

The MRC@UCL Centenary Science Fair will be a family fun day for all ages and will include lab tours, talks, hands-on activities, interactive demonstrations, games and exhibitions. There will be stalls and exhibits in the UCL Cloisters off the main quad, and a treasure hunt for younger visitors. Some of the groups involved and activities planned include: The Centre for Medical Molecular Virology will run science workshops offering a fun, hands-on experience of what the centre does. Including DNA extraction, testing pipetting skills and allowing visitors to demonstrate creative flair by designing and drawing their own interpretations of viruses. The Unit for Lifelong Health and Ageing will exhibit research findings about the National Survey of Health and Development (NHSD), alongside a timeline of public interest milestones. They will also host a variety of activities, including testing grip strength and measuring reaction times.  Students from the Laboratory for Molecular Cell Biology will show what it's like to work in a lab, with various interactive presentations and demonstrations, and the opportunity to discuss careers in medical research. The MRC fellows at UCL will give a series of talks aimed at the general public highlighting the biomedical research funded by the MRC. These talks will focus on the big challenges in biomedical research including cancer, heart disease, infections and diseases of the nervous system. The Seminar series will be officially started by Nobel laureate and one of the BBC's 'Beautiful Minds', Sir Tim Hunt In addition, visitors can sign up for visits to the research labs at the Laboratory for Molecular Cell Biology.

Programme 3: Cellular Molecules Critical for Viral Replication


High-throughput screening for host targets influencing viral replication and drug susceptibility


Programme Co-ordinator: Prof Ari Fassati

Recent advances in genomics, proteomics, chemistry and automation allow the investigation of host-pathogens interactions on a global scale by high-throughput approaches. By creating an infrastructure to perform high-throughput screens we can:

  • Discover genes and molecules important for specific steps of the viral life cycle and their broader physiological functions
  • Identify cellular factors influencing viral fitness and ability to replicate in different hosts and cell types
  • Map druggable cellular targets required for viruses replication by chemical genetics
  • Select broadly cross-neutralizable epitopes for vaccine development
chemical structure

The identification of novel host factors necessary for virus replication or the host anti-viral response will expand our knowledge of both basic cellular mechanisms and how these are exploited by viruses. Furthermore, identification of such factors may provide potential targets for therapy that will be less sensitive to virus mutation than current antiviral drugs. Indeed, the only successful case of HIV-1 eradication has been achieved by eliminating the CCR5 co-receptor, a host factor, by bone marrow transplantation. Finally, discovering virus host-dependency factors and understanding their biological function and mapping broadly cross-neutralizable viral epitopes will provide the base knowledge for screenings to determine or predict susceptibility to specific virus infections, response to treatment and likelihood to develop drug resistance.

SCREENING FACILITIES

The MRC has recently awarded to the Laboratory for Molecular and Cell Biology (LMCB) and the Wohl Virion Centre, UCL, a ~£2 million Translational Research Centre grant to set up a high-throughput screening and imaging facility. The Centre will be primarily based at the LMCB with one core facility within the category 3 labs of the Wohl Virion Centre, to perform screening work with human pathogenic viruses. This is currently the only facility of its kind in an academic environment in the UK. This facility will allow the screening of libraries of short hairpin RNA (shRNA), siRNAs, small compounds and antibodies against a diverse collection of viruses and primary cells.

The MRC Centre for Medical & Molecular Virology (CMMV) will interact closely with the MRC Translational Research Resource Centre (TRRC), which will provide essential infrastructure for imaging, data analysis, management and storage; the Centre of Biological and Medicinal Chemistry, UCL (Prof. David Selwood), which will provide access to one chemical library of ~30,000 diverse compounds, reformatting and curation services, chemi-informatics, virtual screening and support with focused libraries selection; The Department of Chemistry, UCL (Prof. Steve Caddick), which will provide novel synthetic compounds, not available to external organizations and help with compound optimization for target identification; the MRC Technology section (Dr. Justin Bryans), which will provide access to another chemical library and also links with industrial partners to help streamline commercially exploitable discoveries.

Use of infrastructure The infrastructure will be open to all members of the CM&MV and the TRC for work with viruses and the host response against them. It will also be accessible, on a cost-recovery basis, to the broader UCL community and to other academic institutions and biotech companies. A committee has been set up with members from the CMMV and TRRC Centre and the Departments of Chemistry and Medicinal Chemistry to streamline projects:

Dr Ariberto Fassati (CMMV)

Dr Robin Ketteler (Chair)(TRRC)

Dr Catherine Kettleborough (MRCT)

Prof Mark Marsh (TRRC)

Dr David Selwood (UCL LMCB)
