Key takeaways

Type 1 diabetes occurs when the immune system attacks and destroys insulin-producing beta cells in the pancreas
Islets of Langerhans are cell clusters in the pancreas that contain beta cells responsible for insulin production
Insulin regulates blood sugar levels, and without it, blood sugar can become dangerously high or low
Unmanaged blood sugar can lead to long-term complications affecting the eyes, kidneys, nerves, blood vessels, and heart
Islet transplantation is an area of active research in the evolving landscape of type 1 diabetes treatment

How Type 1 Diabetes Develops

Type 1 diabetes occurs when the body's immune system attacks and destroys the insulin-producing beta cells in the pancreas. This process results in little to no insulin production, leaving the body unable to regulate blood sugar effectively. Unlike type 2 diabetes, which develops gradually, type 1 is an autoimmune condition where the immune system mistakenly targets its own cells.

The Role of Insulin and Blood Sugar

Insulin is a hormone released by the pancreas that plays a critical role in regulating blood sugar levels, also called blood glucose. This regulation is essential for maintaining health. Without adequate insulin, blood sugar can swing to dangerous extremes—either too high or too low—creating serious health risks.

Understanding Islets of Langerhans

The pancreas is an organ along the digestive tract that functions as both a gland and part of the digestive system. About 2% of the pancreas is made up of cell clusters called islets of Langerhans, which contain the beta cells responsible for producing and releasing insulin. These specialized cells are the target of research aimed at restoring insulin production.

Long-Term Complications of Unmanaged Blood Sugar

When blood sugar remains unmanaged over time, it can damage multiple organ systems throughout the body. Potential complications include damage to the eyes, kidneys, nerves, and blood vessels, as well as heart disease. In severe cases, uncontrolled blood sugar can be life-threatening, which is why managing type 1 diabetes effectively is essential.

Islet Transplantation: A Developing Field

Islet transplantation represents an evolving area of type 1 diabetes research. As scientists and clinicians continue to study this approach, the landscape of potential treatments for type 1 diabetes continues to develop. This research builds on a growing understanding of how islets function and how they might be restored or replaced in people with type 1 diabetes.
