PROJECT OVERVIEW

Rheumatic autoimmune diseases such as rheumatoid arthritis, systemic lupus erythematosus, systemic sclerosis, and Sjögren’s syndrome are associated production of specific autoantibodies. The reasons for failure of immune tolerance to a finite number of autoantigens are poorly understood. Using a bespoke microfluidics platform, the supervisors have developed a workflow to sequence paired immunoglobulin heavy and light chain genes for hundreds of thousands to millions of B cells in a single blood sample. The student will use this platform to characterise the full immunoglobulin repertoire of naïve, activated, and antibody-secreting B cell subsets in the peripheral blood in samples from patients with autoimmune disease, compared to the same B cell subsets in healthy donors. This work will lead to a valuable atlas of immunoglobulin repertoire breadth at different stages of the B cell lifespan and will help to identify the points at which self-tolerance may fail in autoimmune disease.
