Emerging concepts and success stories in type 1 diabetes research: a roadmap for a bright future.

Type 1 diabetes treatment stands at a crucial and exciting crossroad since the 2022 U.S. Food and Drug Administration (FDA) approval of teplizumab to delay disease development. In this Perspective article, we discuss four major conceptual and practical issues that emerged as key to further advance type 1 diabetes research and therapies. First, collaborative networks leveraging the synergy between the type 1 diabetes research and care community members are key to fostering innovation, know-how and translation into the clinical arena worldwide. Second, recent clinical trials in presymptomatic stage 2 and recent-onset stage 3 disease have shown the promise, and potential pitfalls, of using immunomodulatory and/or beta-cell protective agents to achieve sustained remission or prevention. Third, the increasingly appreciated heterogeneity of clinical, immunological, and metabolic phenotypes and disease trajectories is of critical importance to advance the decision-making process for tailored type 1 diabetes care and therapy. Fourth, the clinical benefits of early diagnosis of beta-cell autoimmunity warrant consideration of general population screening for islet autoantibodies, which requires further efforts to address the technical, organizational and ethical challenges inherent to a sustainable program. Efforts are underway to integrate these four concepts into the future directions of type 1 diabetes research and therapy.
