Pulsatile insulin of Medicine at the University of California, Davis, led the field as a pioneer of using pulsatile insulin in the treatment of diabetes. Dr. Aoki’s work focused on the role of liver dysfunction in diabetic metabolism. He theorized that end organ damage in diabetes is caused by abnormal hepatic glucose metabolism, inadequate insulin delivery, and insulin resistance. He called his approach Metabolic Activation Therapy (MAT), which consisted of an ever-increasing baseline of insulin using Respiratory Quotient to determine the efficiency of treatment (US Patent 4,826,810). Normally, insulin is secreted from the pancreas in pulses into the portal vein which brings
Insulin signal transduction pathway region called Islets of Langerhans. In the islets of Langerhans, there are beta-cells, which are responsible for production and storage of insulin. Insulin is secreted as a response mechanism for counteracting the increasing excess amounts of glucose in the blood. Glucose in the body increases after food consumption. This is primarily due to carbohydrate intake, but to a much lesser degree protein intake ()(). Depending on the tissue type, the glucose enters the cell through facilitated or passive diffusion. In muscle and adipose tissue, glucose enters through GLUT 4 receptors via facilitated diffusion (). In brain, kidney and retina, glucose
