Description | The methodologies we have developed in this project represent a significant advance in the application of synchrotron x-ray approaches to analyze human tissues. In particular, we have used the exceptional chemical and magnetic sensitivity of x-ray techniques to map the biochemistry of brain tissue on sub-cellular length scales, enabling the detection of nanoscale deposits of copper and iron in differing forms. These nanoscale deposits were found within amyloid plaques, a hallmark pathological lesion of Alzheimer's disease. We relate them to links between disrupted metal homeostasis, the development of Alzheimer's disease, and the formation of pathological amyloid lesions. Concurrently, we developed new methods that use x-ray chemical spectroscopic signatures to map the spatial distribution of important biological compounds of relevance to neurodegenerative diseases. In addition to studying ex vivo tissue, we also performed experiments on in vitro samples, and established a link between amyloid aggregation and the chemical reduction of iron biominerals within the iron storage protein ferritin. Together, these experiments reveal a new level of complexity in the role of metals in neurodegenerative diseases and add new concepts to our current understanding of human neurobiology. Further to this, the project unveiled an unexplored fundamental step in the development of Alzheimer's and related diseases, and opened up new research avenues for the study of disease aetiology, treatment, and diagnosis. In addition, our findings raise questions about the (patho)physiological impact of amyloid in association with iron and other metals, especially given the properties of the iron, copper, and calcium forms detected in association with the amyloid plaques. |
Exploitation Route | Through this project, we were able to engage with the global academic and clinical research communities, and successfully demonstrated how specialist techniques such as x-ray spectromicroscopy and FTICR mass spectrometry can be applied to new research areas crossing biochemistry and medical themes. The results of the project have opened up new research avenues for the study of the aetiology, treatment, and diagnosis of neurodegenerative and other diseases where nanoscale biochemistry plays a significant role. We are already observing evidence of the impact of our work with our project publications receiving rapid and diverse recognition across the global academic and medical community. Further collaborative projects that build on our successes here are currently in development, including a collaborative project funded by the Kleberg Foundation (PI Prof George Perry, UTSA, USA) that challenges long-held assumptions about the toxicity of amyloid in the human brain. |

Description | The impact of this work is recorded against grant ref EP/N033140/1. Additionally, we received a 6 month impact reports for the Futurum article that was generated as one of the outputs from this project as a public engagement/education resource: https://futurumcareers.com/shining-a-light-on-the-role-of-trace-metals-in-neurodegenerative-diseases The October 2022 impact report showcased the reach and use of the article as follows. Full details are available on request. Our article was published in Futurum on 14th May 2022, and over the next 6 months our resource reaching over 32k people via social media (Twitter, Facebook, Pinterest, Instagram) and via the dedicated article website. This has led to hundreds of 'likes' and downloads, with some continuing to download the activity sheets as well as the article, and the materials are also being downloaded from other sites as a free international resource for teachers (e.g. www.tes.com/teaching-resource/resource-12678046, https://www.teacherspayteachers.com/Product/The-role-of-trace-metals-in-neurodegenerative-diseases-8073701?st=f17c0f85, and https://www.scientix.eu/resources/details?resourceId=29799). The resource highlights the use of advanced analytical science methods in the study of brain disorders, and also highlights the role of major science facilities - in this case, Diamond Light Source synchrotron in the UK. Subsequently, the findings in this EPSRC project contributed to an invitation to PI Prof Joanna Collingwood to be interviewed as one of Diamond Light Source's 'Leading Lights', creating a resource for Diamond Light Source to profile the careers of synchrotron facility users to a general audience. The interview was broadcast on New Years Day 2024, https://www.diamond.ac.uk/Home/News/Campaign/Leadinglight/Joanna-Collingwood.html |

Description | We successfully demonstrated the x-ray magnetic circular diochroism method for use in spectromicroscopy, for the first time at beamline I08 at Diamond Light Source. This method enables the magnetic character of nanoscale regions to be assessed within sample. Using this method we were able to determine the magnetic state of some iron biomineral inclusions in Alzheimer's plaque material extracted from human brain tissue. We have added this new data to paper currently under revision for the journal Nanoscale. |
