The MSc by Research programme at the University of Aberdeen is for students interested in a research-intensive master's degree. It is designed specifically to enhance your skills for a PhD or research career. If you have your own ideas for a research project in this area, we would love to hear from you! Please reach out to one of the project supervisors above to discuss your ideas.
You can find further information about our academic requirements and programme structure here.
Immune function in mammalian species, including humans, declines during ageing and is multi-faceted. From a human health perspective, this poses a considerable challenge as people are living for much longer than in previous decades and centuries because of advances in medicine, nutrition, and public health. An unwell ageing population places huge pressures on health care systems. Therefore, an understanding of how the immune system ages, and how this decline can be slowed or prevented is a pressing global challenge. The Morgan lab at the Institute of Medical Sciences, University of Aberdeen, combines experimentation and computation to study how ageing and our genetic make-up combine to shape our immune systems.
Data in my lab indicates that an inhibitory immune checkpoint protein called CTLA-4 (Krummel & Allison, 1995) is up-regulated in older people, which may explain why their immune systems are less able to fight off pathogens. CTLA-4 is expressed on different types of T cells, including memory and regulatory cells. CTLA-4 works by grabbing a protein required for T cell stimulation on the surface of antigen presenting cells, called CD80, and brings it inside the T cell where it is degraded – a process called transendocytosis (Qureshi et al. 2011). Regulatory T cells express the highest levels of CTLA-4 however, it is also up-regulated on activated T cells. It is not known how ageing increased CTLA-4 affects transendocytosis and T cell activation.
In this project, the student will use a novel T cell stimulation system to investigate the impact of ageing on T cell function, activation, and responses between young and old people. They will use a combination of flow cytometry, fluorescent, confocal, and live cell time-lapse microscopy to investigate how ageing shapes T cells activation between young and old people. The objectives are to investigate (a) whether T cell activation is different between young and old people, (b) test if transendocytosis on regulatory and activated T cells is affected by ageing, and (c) resolve how genetic variants affect T cell activation, transendocytosis and function. This project will provide opportunities to develop cutting edge experimental and bioinformatic skills, including in image analysis and genetics. Depending on project progress, opportunities to generate and analyse single-cell RNA-sequencing data may arise.
This project would suit a student interested in microscopy, cell biology, immunology or interdisciplinary research that bridges experimentation and computation (no computational experience required).
