Insulin (medication) to develop an orally available insulin. Many of these approaches employ nanoparticle delivery systems and several are being tested in clinical trials. Another improvement would be a transplantation of the pancreas or beta cell to avoid periodic insulin administration. This would result in a self-regulating insulin source. Transplantation of an entire pancreas (as an individual organ) is difficult and relatively uncommon. It is often performed in conjunction with liver or kidney transplant, although it can be done by itself. It is also possible to do a transplantation of only the pancreatic beta cells. However, islet transplants had been highly experimental
Insulin resistance is a prominent change of metabolic conditions, under which the mother has to reduce her muscles' insulin sensitivity to spare more glucose for the brains (the mother's brain and the fetal brain). This can be achieved through raising the response threshold (i.e., postponing the onset of sensitivity) by secreting placental growth factor to interfere with the interaction between insulin receptor substrate (IRS) and PI3K, which is the essence of the so-called "adjustable threshold hypothesis" of insulin resistance. It is well known that insulin regulates the conversion of carbohydrates into fats (triglycerides) by promoting the absorption of, especially, glucose from the
