Flashcards
Diabetes
Diabetes
A condition characterized by high blood sugar levels caused by the body's inability to produce or effectively use insulin.
Insulin
Insulin
A hormone produced by beta cells in the pancreas that acts as a key, allowing cells to absorb glucose from the blood.
Type 1 Diabetes
Type 1 Diabetes
A type of diabetes where the body's immune system destroys the insulin-producing cells in the pancreas.

Study Notes
Insulin Discovery - Lecture Notes
- Lecture Focus: The discovery of insulin, its connection to Aberdeen, and broader significance in drug discovery.
- Global Diabetes Impact: Over 400 million people worldwide are affected by diabetes. In the UK, 10% of NHS budget is allocated to diabetes.
- Diabetes Types:
- Type 1: Characterized by a lack of insulin production.
- Type 2: Body's inefficient utilization of produced insulin.
- Diabetes Definition: High blood sugar levels, historically identified through sweet urine.
- Insulin's Role: A hormone produced by beta cells in the pancreas, acting as a key to allow cells to absorb glucose from blood.
- Without Insulin: Glucose cannot enter cells, causing high blood sugars and cellular starvation.
- Early Treatment Attempts: Initial remedies included ineffective methods like opiates and digestive enzymes.
- Key Figures in Insulin Discovery:
- John MacLeod: Aberdeen graduate and physiology professor.
- Frederick Banting: Canadian doctor who proposed the idea.
- Charles Best: Banting's assistant.
- James Collip: Biochemist who improved insulin extraction.
- Timeline of Insulin Discovery:
- 1920: Banting proposed isolating insulin-producing pancreatic tissue in dogs.
- 1921: Early successful experiments reducing blood sugar in dogs.
- 1922: First successful human trial on a 14-year-old diabetic patient.
- Challenges in Insulin Development:
- Inconsistent results in early extracts.
- Conflicts amongst researchers on methodology and credit.
- James Collip's expertise led to consistent insulin extraction.
- Production and Global Impact: Eli Lilly and Novo Nordisk initiated industrial-scale insulin production, initially using pig pancreases.
- Effect on Patients: Transformed diabetes from a fatal condition to a manageable one, allowing patients to live longer and fuller lives.
- Legacy and Recognition: The 1923 Nobel Prize was awarded to Banting and MacLeod for their work. MacLeod later returned to Aberdeen as professor and memorials exist in Duthie Park.
- Modern Diabetes Treatments: Insulin remains administered via injection; ongoing research includes stem-cell therapy and islet cell transplants.
- Diabetes Management Challenges: Currently, diabetes management is a significant financial burden on the NHS, exceeding £10 billion annually.
- Final Thoughts: The insulin discovery was a remarkable achievement, completed within two years, and demonstrated rapid innovation. It continues to save millions of lives and influence medical science.
