Degeneration of the primary motor cortex is a defining feature of amyotrophic lateral sclerosis (ALS), which is associated with the accumulation of microscopic protein aggregates in neurons and glia. However, little is known about the quantitative …
In this proof of principle experiment, we demonstrate that MALDI-MSI combined with classical LCM LC-MS/MS has the potential to spatially resolve metabolic signatures in human brain at cellular resolution. Abstract & Talk given - The Oxford Metabolic Health Symposium 2020, 30th June – 3rd July 2020.
Diffusion-weighted steady-state free precession (DW-SSFP) is an SNR-efficient diffusion imaging method. The improved SNR and resolution available at ultra-high field has motivated its use at 7T. However, these data tend to have severe B1 …
LC-MS based mass spectrometry imaging of proteins has the potential to provide novel insights into the proteome of tissues. Abstract - Presented at the Oxford Metabolic Health Symposium 2020, 30th June – 3rd July 2020.
Here we apply a sensitive, spatially resolved workflow for the proteomic analysis of a tumour to identify proteins that display spatial expression patterns within the tissue in an unsupervised manner. Abstract and Poster - ASMS Conference on Mass Spectrometry and Allied Topics, May 31st - June 4th 2020.
Linking tissue microstructure with diffusion MRI signals throughout the brain Abstract and Poster - Whistler Scientific Workshop on Brain Functional Organization, Connectivity, and Behavior, March 1st - March 4th 2020.

The detection of specific TDP-43 peptides able to quantify the pathological fragments of TDP-43 in post mortem ALS brain tissue, offers the opportunity to develop an in vivo assay to measure pathological TDP-43. This would have major diagnostic, stratification and pharmacodynamic biomarker potential. The finding of CTF in cases labelled as AD may reflect the recent identification of a sub-group labelled Limbic-predominant Agerelated TDP-43 Encephalopathy. Published Abstract (Journal of Amyotrophic Lateral Sclerosis and Frontotemporal Degeneration, volume 20, S1, November 2019) and Poster - 30th International Symposium on ALS/MND, December 4th - 6th, 2019.
Diffusion MRI (dMRI) has great potential for studying the complexity of white matter fibre architecture non-invasively. However, because dMRI is an indirect measure of this microstructure, we require validation datasets for two main purposes. (i) to relate dMRI to microscopy data that directly measures the microstructure of interest; and (ii) to relate high-quality dMRI data to more conventional data quality. We present the NAMETBC dataset which addresses both of these goals.
