Project Description

Disability and dementia define the devastating diseases Multiple Sclerosis (MS) and Alzheimer’s Disease (AD), but what drives the neuroinflammation and neurodegeneration? New research is focusing on the choroid plexus (ChP), a highly vascular structure hidden deep in the brain’s fluid-filled cavities. ChP is emerging as a major interface between the peripheral immune and central nervous system, an area of increasing importance in MS and AD. However, ChP also transports thyroid hormone (TH) into cerebrospinal fluid (CSF) which is then distributed throughout the brain.

TH is vital for neurophysiology and immunometabolism such as neurogenesis, growth factors, myelination, synapse formation, microglial activation and phagocytosis. Moreover, work shows ChP is inflamed in MS and AD where it may be vulnerable to pathogens including SARS-CoV-2.

This PhD will help determine if MS and AD ChP pathology leads to altered TH transport that then causes chronic inflammation and neurodegeneration in MS and AD. The student will use cutting-edge facilities to study TH metabolism and develop expertise in a range of laboratory techniques. These involve isolation of blood macrophages and in vitro cell culture for a human ChP model with immune assays and western blot; MS and AD human tissue bank brain and ChP samples for immunohistochemistry and fluorescence microscopy.

Overall, the project explores exciting concepts in macrophage biology, neurobiology, neurology and neuropathology. It is hoped the data will contribute to new clinical imaging and drug trials for MS and AD.

Eligibility

Applicants should have a first or upper second class honours degree in an appropriate biology related subject. A masters qualification or previous laboratory experience within the area of neuroscience would be an advantage.

If your first language is not English, you will need to meet the minimum English requirements for the programme, IELTS Academic score of 6.5 (with no less than 5.5 in each component test area) or equivalent.

The studentship is supported for 3 years and includes full home tuition fees plus a stipend of £18,655 per annum 2024/25 rate.  The studentship will only fully fund those applicants who are eligible for home fees with relevant qualifications.  Applicants normally required to cover international fees will have to cover the difference between the Home and the international tuition fee rates.
