Cornall Group - B cell development and immune regulation
Understanding B cell development and diseases associated with abnormal antibody production.
About the Research
Our aims are to understand B cell development and diseases associated with abnormal antibody production. Inadequate or excessive immune responses lead to immunodeficiency or autoimmune and inflammatory diseases, which place a major economic and social burden on world health and the quality of human life. So, we are interested in the normal processes of immune function and how individuals vary due to inherited or acquired differences.
Investigating human immunodeficiency and other forms of inherited disease is a good way to discover new immune functions and a great way to train in the field. One project involves a new form of inherited B cell specific immunodeficiency caused by deficiency in a novel cation transporter, caused by a variety of different mutations in individuals in the Europe and the USA. Other projects involve the study of other forms of inherited disease and building transgenic and CRISPR targeted models.
The threshold for activation of B cell receptor is important because it determines the selection of B cells into different subsets, the response to foreign antigens and immune tolerance to self. We are beginning to appreciate that the threshold varies through the development of B cells and probably through the lifetime of an individual; but we know little about its molecular basis or how it might be manipulated therapeutically. These are some of the most fundamental questions in immunology with broad implications.
Our third area of interest is in developing new strategies to inhibit the immune response using antibody therapeutics. These projects are a collaboration with Professor Simon Davis’ group and are described by him.
Our student projects cover all of these areas. We will use molecular biology, genetics, cellular immunology, gene targeting, and immunoglobulin and TCR transgenic models to study these basic questions in immunology.
Our programme is suitable for someone with a background in biochemistry, immunology, medicine or a similar degree who is interested in using cellular, genetic and biochemical approaches to studying human disease. It may be appropriate for a student in chemistry who wants to learn immunology and apply basic principles to the study of cells with imaging etc. A wide variety of lab techniques will be used and our students become expert in cell biology and immunology. Experience of immunology is not a requirement, since teaching is available in the University and lab.
Students will be enrolled on the MRC WIMM DPhil Course, which takes place in the autumn of their first year. Running over several days, this course helps students to develop basic research and presentation skills, as well as introducing them to a wide-range of scientific techniques and principles, ensuring that students have the opportunity to build a broad-based understanding of differing research methodologies.
Generic skills training is offered through the Medical Sciences Division's Skills Training Programme. This programme offers a comprehensive range of courses covering many important areas of researcher development: knowledge and intellectual abilities, personal effectiveness, research governance and organisation, and engagement, influence and impact. Students are actively encouraged to take advantage of the training opportunities available to them.
As well as the specific training detailed above, students will have access to a wide-range of seminars and training opportunities through the many research institutes and centres based in Oxford.
All MRC WIMM graduate students are encouraged to participate in the successful mentoring scheme of the Radcliffe Department of Medicine, which is the host department of the MRC WIMM. This mentoring scheme provides an additional possible channel for personal and professional development outside the regular supervisory framework. The RDM also holds an Athena SWAN Silver Award in recognition of our efforts to build a happy and rewarding environment where all staff and students are supported to achieve their full potential.
