About

The Thomas Group’s research is focused on the study of autoimmune disease and restoration of tolerance. We aim to understand dendritic cell function, analyse T cell responses, study tolerance in vivo and the microbial influences on autoimmune disease and tolerance. We translate our insights to develop technological solutions to restore tolerance by targeting dendtitic cells. We undertake clinical trials of tolerance in autoimmune diseases, and clinical studies of risk evaluation and modification in rheumatoid arthritis, spondyloarthritis and type 1 diabetes. 

Through this work, Ranjeny Thomas and her team developed dendritic cell and liposome products for clinical trials of antigen-specific immunotherapy targeting dendritic cells in rheumatoid arthritis. The team has also contributed major insights into the pathogenesis of spondyloarthropathy and autoimmune diabetes, leading to the development of disease biomarkers and therapeutic strategies. Ranjeny was founder and a director of the spin-off company, Dendright, developing antigen-specific technologies to suppress rheumatoid arthritis.
