Synchronization of mouse islets of Langerhans by glucose waveforms.
Pancreatic islets secrete insulin in a pulsatile manner, and the individual islets are synchronized, producing in vivo oscillations. In this report, the ability of imposed glucose waveforms to synchronize a population of islets was investigated. A microfluidic system was used to deliver glucose waveforms to ∼20 islets while fura 2 fluorescence was imaged. All islets were entrained to a sinusoid...
متن کاملGrowth of the islets of Langerhans.
factor; here according to current concepts the pituitary growth hormone may play an important part. In the case of the "pre-diabetic fathers," the factor of inheritance must be the determining factor. Jackson contends that when a woman gives a history of having had several large babies, the diagnosis of a pre-diabetic state is justified to such an extent that treatment should be started before ...
متن کاملNegative feedback synchronizes islets of Langerhans.
Insulin is released from the pancreas in pulses with a period of ~ 5 min. These oscillatory insulin levels are essential for proper liver utilization and perturbed pulsatility is observed in type 2 diabetes. What coordinates the many islets of Langerhans throughout the pancreas to produce unified oscillations of insulin secretion? One hypothesis is that coordination is achieved through an insul...
متن کاملCongenital absence of islets of Langerhans.
A small-for-dates male infant who developed acute metabolic acidosis shortly after birth had diabetes and died aged 40 hours. At necropsy there was an absence of any recognizable islets of Langerhans though lymphorecticular aggregates were found. This was the fourth child of healthy unrelated parents whose first child, also a male, died at 48 hours under similar circumstances. It is suggested t...
متن کاملTransplantation of islets of Langerhans: new developments.
The clinical results recently reported by the Edmonton group in recipients of allogeneic islet grafts, all of whom achieved at least temporary insulin independence, has rekindled interest in transplantation of islets of Langerhans as a means to cure diabetes. Long-term islet graft survival has been achieved in a non-human primate pre-clinical model with a protocol of T-cell signaling blockade u...
