Insulin and Type 1 Diabetes

• Insulin saves lives, BUT with…

– Life-threatening bouts of hypoglycemia

– Poor glucose control and long-term complications

– Frequent finger sticks and counting carbs

– Constant vigilance

• Insulin lowers blood glucose levels no matter what

– Too much: Hypoglycemia

– Too little: Hyperglycemia and ketoacidosis

• Effective control requires glucose-responsive delivery

-cell glucose-stimulated insulin release

• Provide the missing -cells: regeneration or transplantation

• Mimic the -cell function

Negligible below 100 mg/dl

Rapid increase between

100 and 400 mg/dl

Saturated maximum

above 400 mg/dl

The artificial pancreas approach

• SmartCells makes the insulin molecule glucose-responsive

• Eliminates the need for cells, pumps, sensors and algorithms

Assume the insulin

molecule cannot be

changed

Renard, E., Curr. Opin. Pharmacol. 2 (2002) 708-716.

Better algorithms and

device integration

Better accuracy,

redundancy,

biocompatibility

1. IPC and GBM combine to form insoluble network

2. Free glucose molecules displace the IPC from the GBM

3. The matrix erodes from the surface inward

4. The released IPC lowers glucose levels in the body

5. The matrix stops eroding until the next glucose challenge
