Research summary

Detection of protein misfolding diseases, particularly prions.

Current research interests

The application of RT-QuIC as a diagnostic tool for clinical identification in protein misfolding diseases. The production & use of A-Syn, Tau, TDP-43 and truncate PrP in RT-QuIC. Investigating how physical parameters affect the reproducibility of prion protein behaviour in diagnostic assays.

Past research interests

Protein folding, assay development, fluorescence technologies, small molecule inhibitors, protein-protein interactions.

Knowledge exchange

Dissemination of best practice - He is recognised as an international expert on the RT-QuIC technique. Since 2015, his advice has been sought out by 17 groups from Mexico to China. 15 of these laboratories have gone on to request physical support.

Project activity

Neil's work facilitates the surveillance of prion disease in the United Kingdom and Northern Ireland.

He has expertise in a clinical diagnostic technique called the "Real Time Quaking Induced Assay" (RT-QuIC) and, as part of an analytical service for the NHS, he runs the clinical laboratory side of this test. Edinburgh is recognised internationally as a centre of excellence for RT-QuIC. He produces the specialist materials required for these tests and makes them available to the national surveillance centres of many European countries.

He evaluates new applications and improvements of RT-QuIC as well as presenting his research work to external groups.
