Advances in insulin therapy from discovery to β-cell replacement

Area of Science:

• Endocrinology
• Metabolic Diseases
• Biotechnology

Background:

• The advent of insulin therapy in the 1920s, utilizing animal-sourced insulin, marked a significant breakthrough in managing diabetes mellitus.
• Subsequent scientific progress, including the cloning of human insulin complementary DNA (cDNA), facilitated the creation of recombinant human insulin.

Purpose of the Study:

• To provide a historical overview of insulin therapy evolution for diabetes.
• To highlight key advancements in insulin production and treatment modalities.
• To explore the potential future of diabetes management through beta-cell replacement therapy.

Main Methods:

• Review of historical scientific literature on insulin therapy.
• Analysis of biotechnological advancements in insulin production.
• Prospective evaluation of emerging therapeutic strategies for diabetes.

Main Results:

• Early insulin therapy, derived from porcine and bovine sources, dramatically improved diabetes outcomes.
• Recombinant DNA technology enabled the production of human insulin with enhanced characteristics.
• Beta-cell replacement therapy is emerging as a promising future direction for diabetes treatment.

Conclusions:

• Insulin therapy has undergone substantial evolution, from animal extracts to bioengineered human insulin.
• Continued innovation in biotechnology and regenerative medicine is poised to transform diabetes care.
• Beta-cell replacement therapy represents a potential paradigm shift in managing diabetes in the future.
