As we reflect on the legacies of our nation's forefathers this month, we also turn our thoughts to those who have shaped the course of diabetes care and advocacy. Groundbreaking figures like Dr. Elliot Joslin, widely recognized for his pioneering efforts in diabetes education and care, helped lay the foundation for modern diabetes management. The world owes a tremendous debt to Frederick Banting, Charles Best, and John Macleod, whose discovery of insulin over a century ago transformed diabetes from a fatal disease into a manageable condition.

Pioneers in Diabetes Research

Frederick Banting, Charles Best, and John Macleod made a groundbreaking discovery in 1921 that revolutionized diabetes treatment. Their work led to the isolation and purification of insulin, transforming diabetes from a fatal disease into a manageable condition. Banting's personal experience with the loss of a childhood friend to diabetes influenced his determination to find a cure, ultimately resulting in him becoming the youngest Nobel Prize recipient in Medicine in 1923.

Dr. Elliot Joslin, another significant figure, established the Joslin Clinic in Boston. His work dramatically reduced diabetes mortality rates and pioneered patient education approaches still used today.

Some additional contributors to diabetes research

• Oskar Minkowski and Joseph von Mering: In 1889, they discovered the link between the pancreas and diabetes by removing a dog's pancreas, leading to severe diabetes.

• Moses Barron: His 1920 article on the relationship between islets of Langerhans and diabetes influenced Frederick Banting's focus on diabetes research.

• Matthias H. Tschöp: Recipient of the 2023 Banting Medal for Scientific Achievement, he discovered novel classes of dual and triple gut hormone drugs that have transformed the fight against obesity and diabetes.

• Paul Zimmet: A global leader in transforming the understanding and threat of diabetes, whose advocacy shaped international diabetes policy.

These individuals, among many others, have significantly advanced our understanding and treatment of diabetes through their groundbreaking research and clinical work.

Modern Advancements: 2024-2025 Breakthroughs

NEW: The past year has brought remarkable progress in diabetes care:

Smart Insulin Technology:
Researchers are developing glucose-responsive insulin that activates only when blood sugar rises—potentially eliminating the need for constant monitoring and dose calculations. Early trials show promising results for both Type 1 and Type 2 diabetes.

Artificial Pancreas Systems:
Closed-loop insulin delivery systems have become more sophisticated, with several FDA-approved hybrid systems now available. These devices automatically adjust insulin delivery based on continuous glucose monitoring data, reducing the burden of diabetes management.

GLP-1 and Dual-Action Medications:
The class of medications pioneered by researchers like Matthias Tschöp continues to evolve. New formulations approved in 2024-2025 offer improved glucose control with fewer side effects, and ongoing research explores their potential in preventing Type 2 diabetes progression.

Cell Therapy Advances:
Stem cell-based therapies to restore insulin production are showing promise in clinical trials. In 2024, several patients with Type 1 diabetes achieved insulin independence through experimental islet cell transplantation combined with immunosuppression techniques.

Government Initiatives

The Advanced Research Project Agency for Health (ARPA-H), launched in 2022, continues to drive breakthroughs in diabetes prevention, detection, and treatment. In 2024-2025, ARPA-H funded several initiatives focused on:

• Affordable insulin production technologies

• AI-driven glucose prediction algorithms

• Next-generation continuous glucose monitors

• Diabetes prevention programs targeting at-risk populations

Breakthrough T1D: Continuing the Legacy

Today, organizations like Breakthrough T1D (formerly JDRF), the leading global type 1 diabetes research and advocacy organization, continue the legacy of these pioneers by supporting research to prevent and cure Type 1 diabetes. Their 2025 initiatives include:

• Funding research into immune system modulation to prevent T1D onset

• Supporting clinical trials for beta-cell replacement therapies

• Advocating for equitable access to diabetes technology

• Expanding global diabetes education programs

Their efforts ensure that the pipeline of diabetes research remains robust and promising.

Looking Forward: What's Next in 2026 and Beyond

As we honor these trailblazers and their contributions, we must also look to the future. The fight against diabetes continues, with exciting developments on the horizon:

Precision Medicine:
Genetic testing and AI are enabling personalized diabetes treatment plans tailored to individual metabolic profiles.

Cure Research:
Breakthrough T1D's ambitious goal of finding practical cures for Type 1 diabetes by 2030 is driving unprecedented collaboration between researchers worldwide.

Global Health Equity:
Efforts to make insulin and diabetes technology accessible in low-income countries are expanding, ensuring that the benefits of diabetes research reach all communities.

Together, we can build a future where diabetes is no longer a daily burden, and ultimately, where it's cured.
