WHAT ARE ISLETS OF LANGERHANS? |
The Islets of Langerhans are commonly referred to as "islets" . Islets actually are clusters of cells, with each "islet" containing 3,000 to 4,000 cells.Within each islet are several types of cells, which work together to regulate blood sugar. One cell type is the beta cell. Beta cells sense sugar in the blood and release the necessary amount of insulin to maintain normal blood sugar levels. The immune system mistakenly sees beta cells as "potential danger" and destroys them, causing type 1 diabetes. |
