Description of research:
I Have lead a team who have sought to discover how infection or injury contributes to the outcome of distinct brain pathologies. We have made a number of important discoveries in recent years that have generated collaborations and initiated research programmes in other independent laboratories among which I would highlight the following:
1. Different CNS compartments exhibit distinct responses to cytokines and the aged brain also responds differently to inflammatory challenges;
2. That the liver synthesises chemokines to mobilise immune cells to the blood for subsequent entry to diseased tissue - this pivotal feature of the innate inflammatory response was unknown prior to our studies;
3. That focal MS-like lesions can be reactivated by systemic infections;
4. That a 'window of susceptibility' to inflammatory stimuli exists in infant animals;
5. That TNF induces distinct vascular changes in the brain that lead to the recruitment og platelets and monocytes, which contributes to the outcome og cerebral malaria;
6. That endogenous extracellular vesicles (EVs) are responsible for a brain-liver communication and that changes in the circulating population of can result in alternations in animal behavior;
7. That NMR-based metabolimics can be used to identify distinct CNS pathologies;
8. And that post-translational modifications can be used to generate new targeting agents.
Indeed our imaging studies were the first to show that targeted MRI contrast agents could be used to detect disease in the brain that is not visible with any other imaging modality (MRM 2004, Nature Medicine 2007). This work led to the award of a MRC DPFS translational grant (2010-17) and the formation of a spin-out company.
