Usually, the body's own immune system — which normally fights harmful bacteria and viruses — mistakenly destroys the insulin - producing (
islet, or islets of Langerhans) cells in the pancreas.
Pancreas and
islet transplantation in diabetes mellitus.
Once a significant number of
islet cells are destroyed, you'll produce little or no insulin.
Islet cell transplantation research in the UK The success of a novel
islet transplantation procedure, called the «Edmonton protocol» was reported in an article in the New England Journal of Medicine, 27 July 2000.
The article described how a team of researchers, surgeons and radiologists had successfully carried out a number of
islet cell transplantations in people with Type 1 diabetes, in Edmonton, Canada..
In October 1952, the United States tests its first thermonuclear device, obliterating a Pacific Ocean
islet in the process; nine months later, the Soviets test an H - bomb of their own.
Most cases of type 1 diabetes occur when the body mistakenly sees
the islet cells as a foreign invader and wrecks the thing.
You have between one million and three million
islets of Langerhans in your pancreas, the spongy, six - inch - long organ positioned behind your stomach.
To keep Lady Liberty's hemline dry, the architects propose creating a network of piers,
islets, and underwater kelp forests that would surround Liberty Island as well as Ellis Island, and that would act as buffers to keep back storm surges.
Other mice, with robust beta cells that were good at repairing DNA damage, were able to stay non-diabetic for life, even when
those islets were placed under severe cellular stress.
Maps from the French national marine service revealed that many palm - covered
islets in the bay at Pointe - à - Pitre, the biggest city on the island of Guadeloupe, disappeared between 1820 and 1869, Feuillet told OurAmazingPlanet.
Too little VEGF doesn't grow vessels rapidly enough to maintain the transplanted
islets, which are clusters containing hundreds of cells.
Using cells from cadavers, doctors have been experimentally transplanting pancreatic
islets into humans for decades, but as many as 60 percent of the transplanted
islets die immediately because they are cut off from their blood supply and are killed by an immune response due to direct injection into the bloodstream, and those that survive the transplant usually die within several months.
«In addition to protecting
the islets, our engineered material promotes the formation of new blood vessels to nourish the cells.»
Weaver studied the animal models for as long as 100 days, and found that
the islet clusters transplanted with the hydrogel and VEGF developed many blood vessels and engrafted into their new locations.
«We have engineered a material that can be used to transplant
islets and promote vascularization and survival of the
islets to enhance their function,» said Andrés García, a Regents» Professor in the Woodruff School of Mechanical Engineering at the Georgia Institute of Technology.
While
these islet cell transplants dramatically improved blood sugar control in the short term, all but five of the 36 recipients needed additional insulin shots within two years.
The protein, known as focal adhesion kinase, or FAK, activates an enzyme called AKT, which helps
islet cells in the pancreas to survive.
Introducing a dye into the bloodstream then allowed her to image the growing vasculature around
the islets.
As expected, the hydrogel material disappeared and was replaced by new tissue which grew around
the islets.
«The transplanted
islets need a lot of oxygenation and a connection to the body's circulatory system to sense the glucose levels and transport the insulin,» noted García, who is also the Rae and Frank H. Neely Endowed Chair in Mechanical Engineering.
In addition to looking at mouse models of diabetes, the researchers also showed that exposure of human pancreatic
islet cells — both from healthy donors and from patients with Type 1 diabetes — to fasting - mimicking diet in a dish stimulated insulin production.
In testing done so far,
the islets have been placed into the vasculature of the liver, which has significant blood supply — but might not be the ideal location because of the hostile immune environment.
The imaging provided a clear view of the growing vascular system surrounding
the islet clumps.
«
Islet cells are very precious because we get so few from each donor.
Combining a new hydrogel material with a protein that boosts blood vessel growth could improve the success rate for transplanting insulin - producing
islet cells into persons with type 1 diabetes.
But when
islet cells begin turning into tumors, the FAK protein gets overproduced, researchers found.
Pancreatic
islet clusters are shown on the microscope screen.
Nonetheless, most retained at least
some islet function, protecting them against so - called «hypoglycaemic unawareness», in which people can not recognise the early signs of low blood sugar.
Alpha cells and beta cells are both endocrine cells meaning they synthesize and secret hormones — and they exist right next to one another in the pancreas in structures called
islets.
Diabetes researchers are considering various replacements for insulin injections: Transplanting new pancreatic
islet cells that make insulin, coaxing the patient's own islets to regenerate, or treating diabetics early in the disease with immune - suppressing therapies to prevent their body from destroying the rest of their pancreatic islets.
Using the material and protein combination, the researchers evaluated multiple locations for implanting
the islet cell clusters, the first time such a direct comparison of transplant sites has been made.
I wasn't expecting to see such perfect blood vessel growth into
the islets.»
Pancreatic neuroendocrine tumors, often referred to as «
islet cell tumors» are a type of cancer that arises from hormone - releasing cells in the pancreas.
The JDF Center for
Islet Cell Transplantation will fund 32 researchers to focus on four main goals: Reversing the overactive immune response that kills
islet cells; finding new sources for
islet cell transplants, such as pigs or genetically engineered cells; persuading the body to accept the transplanted cells without immunosuppressive drugs that often trigger worse side effects than the disease; and overcoming the technical difficulties of transplantation.
Researchers have had some success in transplanting
islet cells, but recipients require heavy doses of immune suppression.
There's been a growing realization among diabetes researchers that human
islet development differs significantly from
islet development in typical laboratory animals like mice.»
Kim and his colleagues are planning to continue their studies of pancreatic and
islet - cell development as part of a Stanford focus on diabetes and metabolism research.
Cells in the pancreatic
islets called beta cells are responsible for modulating the body's response to the rise and fall of blood glucose levels after a meal.
«Studying human
islet cells has been a major challenge in the field of diabetes research for decades because the pancreas essentially digests itself shortly after a person's death,» said professor of developmental biology Seung Kim, MD, PhD.
They also developed a unique cell - sorting technique to isolate
islet cells from other cells in the pancreas.
