Description | Key Findings 1 RECEPTOR CROSSLINKING FOR DRUG DELIVERY Through this award we have discovered a universal strategy for delivering therapeutic entities into cells. It is based on binding receptors on the surface of cells using a targeting entity and then driving a therapeutic into the interior of hte cell to reach its target. The results were published in Molecular Therapy and as recognition of the potential impact of these findings the Journal wrote a two page commentary on this work in the same issue and also included one of our images on the cover. Moody et al Molecular Therapy (2015); 23 12, 1888-1898. doi:10.1038/mt.2015.178 Key KEY FINDINGS 2 MAKING SMART NANOPOLYMERS TO DELIVER THERAPEUTICS Work in collaboration with Nottingham University and the University of Paduva in Italy demonstrated that we could design and synthesis nanoparticles that were in a controlled manner (1 temperature and 2. acidicy) able to bind selectively to cancer cells showing high levels of a target protein on their surfaces. This is work was published via two papers 1) Brazzale et al (2017) Nanoscale DOI: 10.1039/C7NR02595E 2) Sayers et al (2018) Bioconjugate Chemistry DOI: 10.1021/acs.bioconjchem.7b00704 Key Findings 3 POLYMER SCIENCE CAN BE COOL AND EXCITING Through this funding a large science exhibition was organised under the title of "Working Polymers" This was held over a eight day period at the Science and Technology Pavilion of the National Eisteddfod of Wales - Meifod Mid-Wales- August 1 - August 8 2015. The aim of this exhibit was to highlight the science underlying polymers and the fact that we are now totally dependent on them but to also bring introduce EPSRC funded research in the Jones laboratory on the use of polymers for designing nanomedicines to target diseases such as cancer. Approximately 130,000 visited the Eisteddfod over this eight day period and >20,000 were counted into the Science Pavilion. The Exhibit was staffed by Cardiff University academics and undergraduate students. Feedback was extremely positive and there was much discussion surrounding the various polymer activities in display e.g. polymer surface of the world cup rugby ball, nappies and cardiac stents with controlled release of drugs. This also attracted the media and interviews were conducted with BBC Radio and TV and also S4C Wales. A major outcome of these is that the public now clearly view science as a fundamental part of Welsh culture and this is why the Science and Technology Pavilion sits proudly and comfortably at the heart of this very large cultural festival. Key Findings 4 Work initiated during the award have resulted in an important publication in the Journal Nanoscale. This related to using fluorescence to track nanoparticles moving in cells. These particles are of significant interests as vectors for therapeutics and diagnostic agents. Using our newly discovered microscopy technique we have identifies (at the nanoscale) that the fluorescence read out may not perfectly align with the location of the nanoparticle. This has significant implications for the academic and industrial sectors who are studying nanoparticle dynamics in cells. Giannakopoulou et al (202) Nanoscale doi.org/10.1039/C9NR08512B Key Findings 5 During the end of the award the Jones group teamed up with Astra Zeneca who were interested in a paper that was published in 2015 from EPSRC funding (Moody el al Molecular Therapy 2015). This led to a new collaboration and funding and a publication in 2019 where nanoparticles cell interactions have been studied in great detail suing a new technology platform called Endocytic profiling that also involved manufacturing a new reagent for analysing the pH (acidity) in cells.

Exploitation Route | A. TAKEN FORWARD The results form this paper and thus award have had immediate impact 1 New Grant Funding from Cancer Research Wales . Project Grant October 2015- April 2017 £101,000. 2 New contract and collaboration with Astra Zeneca to develop more efficient drug delivery systems. £135,000 We will continue to apply for funding to study this further with a view to translating the in vitro data into realistic therapeutic strategies. B. USE BY OTHERS 1. We have discovered an approach for receptor targetting, crosslinking and internalization that we believe will be of significant benefit to therapeutic approaches to address a number of diseases with high societal burden such as cancer. We have developed methods for manufacturing new SMART polymer nanoplatforms for delivering therapeutics to cancer cells. In March 10 202 this article has 35 citations 2. We hope that our Endocytic Profile analysis methodological platform and new research tool will be of significant interest to academia and industry. This will allow them to perform more rigorous pre cinical testing in cell models of drug delivery, using nanoparticles and other vectors as delivery platforms |

Title | Receptor Crosslinking |
Description | The method description is essentially in the title of the manuscript from this EPSRC funded project : Moody et al 2015, Receptor Crosslinking: A General Method to Trigger Internalization and Lysosomal Targeting of Therapeutic Receptor:Ligand Complexes It describes an in vitro crosslinking system that we find is applicable for internalisation of numerous plasma membrane receptors. Crosslinking could be exploited for a wide range of target receptors, for navigating therapeutics through the endolysosomal pathway, for significant therapeutic benefit. |

Results and Impact | Through EPSRC funding (EP/J021334/1) a large science exhibition was organised under the title of Working Polymers; This was held over a eight day period at the Science and Technology Pavilion of the National Eisteddfod of Wales - Meifod Mid-Wales- August 1 - August 8 and officially opened by the First Minister for Wales Carwyn Jones. The aim of this exhibit was to highlight the science of polymers and the fact that we are now totally dependant on them but to also bring introduce EPSRC funded research in the ATJ laboratory on the use of polymers for designing nanomedicines to target diseases such as cancer. Approximately 130,000 visited the Eisteddfod over this eight day period and >20,000 were counted into the Science Pavilion. The Exhibit was staffed by Cardiff University academics and undergraduate students. Public engagement training was provided for all activity staff by Professor Jones. Feedback was extremely positive and there was much discussion surrounding the various polymer activities in display e.g. surface of rugby balls, nappies, cardiac stents with controlled release of drugs. This also attracted the media and numerous interviews were conducted with BBC Radio and TV and also S4C.
