History of FoxP3 and Implications for Therapeutic Intervention in Disease

Fred Ramsdell traces the discovery of FOXP3 from the striking immune phenotype of the scurfy mouse to the mapping and cloning of the responsible gene. He explains how linking a disease phenotype to its genetic cause opened a route to understanding the regulation of immune responses and the biology of regulatory T cells.

The lecture considers FOXP3 as a regulator of immune function and the implications of this history for therapeutic intervention. It argues for the continuing value of phenotype-first research and naturally occurring disease mutations in discovering biological mechanisms and identifying potential treatment targets, even as genome sequencing becomes increasingly routine.
