Research summary

Professor Gray is a clinician-scientist and consultant rheumatologist whose research focuses on the immunological mechanisms that drive autoimmune rheumatic diseases, including rheumatoid arthritis, Sjögren’s disease and systemic lupus erythematosus. Her group studies how B cells contribute to disease initiation, persistence and tissue inflammation, with the aim of identifying mechanisms that can be translated into more selective and effective treatments.

Her work bridges clinical medicine, human immunology and experimental biology. Current research explores pathogenic B-cell states in autoimmune disease, the relationship between circulating and tissue B-cell populations, and how inflammatory tissue environments may shape memory B-cell function. She is also working with academic and industry collaborators to explore the translational potential of these discoveries.

Research highlights

B-cell tolerance: identified a role for self-reactive B1a B cells in immune tolerance to dying cells, challenging established models of autoreactivity.

Inflammation and tissue damage: demonstrated that alpha defensins released from necrotic neutrophils can have anti-inflammatory effects, adding nuance to the view of necrotic cells as danger signals.

Rheumatoid arthritis: discovered an expansion of circulating class-switched double-negative 2 B cells in newly diagnosed, untreated RA, and linked these cells to antibody-secreting cell pathways in inflamed synovium.

Inflammatory memory B cells: identified a memory B-cell state enriched across several autoimmune rheumatic diseases, with potential relevance to disease pathogenesis and therapeutic targeting.

Clinical experience

Professor Gray has more than two decades of experience as a consultant rheumatologist in Edinburgh. She has contributed to the development of Scotland’s largest single rheumatology department and has helped shape services that improve patient care and patient information.

Developed the transitional rheumatology service for teenagers and young adults

Led the early rheumatoid arthritis service

Oversaw the connective tissue disease clinic

Created EdRheum.org as an accessible information and support resource for patients

Equality, diversity and inclusion

Professor Gray has a sustained commitment to equality, diversity and inclusion in higher education and clinical academia. Her work has focused particularly on widening participation, student support and addressing structural barriers to progression.
