Pilot Grants

Recognizing that the engine of R&D is powered primarily through fundamental, mechanistic science, the Colton Center for Autoimmunity funds discovery pilots and other similar research programs. By funding high-risk, high-reward projects, we aim to catalyze new discoveries on fundamental mechanisms of immune function relevant to human autoimmune disease. Although excellent science is always the driving factor, our focus is to prioritize research that identifies or develops new therapeutic targets, exploits new treatments or interventions for mechanistic discovery, introduces new strategic collaborations, and garners additional funding support to promote the long-term sustainability of the Colton Center in its war on autoimmunity.
