Insulin oscillation blood from the pancreas to the liver, which is a major insulin target. Disturbances of the insulin oscillations occur early in type 2 diabetes and may contribute to insulin resistance. Pulsatile insulin delivery to the portal vein or islet cell transplantation to the liver of diabetic patients are therefore attractive therapeutic alternatives. Insulin oscillation The insulin concentration in blood increases after meals and gradually returns to basal levels during the next 1–2 hours. However, the basal insulin level is not stable. It oscillates with a regular period of 3-6 min. After a meal the amplitude of these oscillations increases but
Insulin resistance the likelihood of Type 2 diabetes mellitus. Also, insulin resistance often is associated with a hypercoagulable state (impaired fibrinolysis) and increased inflammatory cytokine levels. Another factor that may promote insulin resistance is Leptin, a hormone produced from the ob gene and adipocytes. Its physiological role is to regulate hunger by alerting the body when it is full. From an adaptation perspective, it is possible that leptin resistance was favorable for survival during periods when food was scarce. Today however studies show that lack of leptin causes severe obesity and is strongly linked with insulin resistance. Leptin replacement in mice with
