PhD Studentship in Rescue of Dysfunctional Lysosomes in the Retinal Pigment Epithelium (RPE) as a New Dry AMD Treatment

Clinical and Experimental Sciences

Location: Southampton General Hospital

Closing Date: Friday 18 September 2020

Reference: 1282620FC
Main Supervisor: Dr J. Arjuna Ratnayaka

Other members of the supervisory team: Professor Andrew J. Lotery (FoM) and Dr David Tumbarello (Biological Sciences).

Amount of stipend and fees: Year 1: £15,385 to include incremental rise until year 3.

Duration of the award: 36 months (3 years), full-time

Project description:

Applications are invited for an exciting new PhD studentship funded by the UK Macular Society investigating how retinal pigment epithelial (RPE) cells become damaged in the eye. RPE cells play a critical role in vision as they look after the light-detecting photoreceptors. With increasing age, complex macromolecules accumulate within RPE which the cell struggles to remove efficiently. This is a major disease-causing pathway leading to irreversible blindness. The project will study how these toxic molecules build-up inside RPE and whether the cells’ degradation system can be boosted to prevent eventual RPE damage and atrophy. Findings from this work can pave the way for developing new treatments for common retinopathies such as age-related macular degeneration (AMD) as well as rare retinal dystrophies. The successful applicant will exploit cellular and mouse models, employing molecular biology, biochemical and imaging techniques. The successful applicant will join a dynamic research group consisting of undergraduate/PGR students and postdocs. The candidate is expected to be highly motivated with an excellent work ethic and the successful candidate will be required to work with mice as part of the project which will include required training.

Informal inquires can be directed to the supervisor Dr J. Arjuna Ratnayaka ().
