Beta cells make up 50-70% of the cells in human islets. (wikipedia.org)
Beta cells can respond quickly to spikes in blood glucose concentrations by secreting some of their stored insulin and amylin while simultaneously producing more. (wikipedia.org)
Beta cells are the only site of insulin synthesis in mammals. (wikipedia.org)
In beta cells, insulin release is stimulated primarily by glucose present in the blood. (wikipedia.org)
Voltage-gated calcium channels and ATP-sensitive potassium ion channels are embedded in the plasma membrane of beta cells. (wikipedia.org)
Type 1 diabetes mellitus, also known as insulin-dependent diabetes, is believed to be caused by an auto-immune mediated destruction of the insulin-producing beta cells in the body. (wikipedia.org)
The islets are composed of different endocrine cell types, of which pancreatic beta-cells are the most common ones. (frontiersin.org)
Insulin is secreted in pulses from pancreatic beta-cells, and these oscillations maintain fasting plasma glucose levels within a narrow normal range. (bvsalud.org)
Within islets, beta-cells exhibit tight synchronization of regular oscillations. (bvsalud.org)
The main hormone regulating the blood glucose levels is insulin, secreted from beta cells, and glucagon, secreted from alpha cells. (lu.se)
My research focus is to understand how we can circumvent the reduced capacity of the pancreatic beta cells to secrete enough insulin, and why the control of alpha cell glucagon secretion becomes disturbed in diabetes. (lu.se)
In beta-cells, CFTR act as a regulator of the Ca 2+ activated chloride channel ANO1 to regulate granular priming and exocytosis of insulin granules. (lu.se)
The study first examined how mice in which almost all beta cells were destroyed-similar to humans with type 1 diabetes-responded to injections of caerulein. (press-news.org)
However, alpha cells do not normally become beta cells. (press-news.org)
The process of alpha cells converting to beta cells does not appear to have any age limitations-it occurred in young and old individuals-including some that had type 1 diabetes for decades. (press-news.org)
So our next step is to find out which molecule(s) caerulein is targeting on alpha cells that triggers their transformation into beta cells. (press-news.org)
In addition to creating new beta cells, another issue that needs to be addressed to achieve a cure for type 1 diabetes is that any new beta cells will be attacked by the autoimmune response present in every patient with type 1 diabetes. (press-news.org)
Islets can influence each other through paracrine and autocrine communication, and beta cells are coupled electrically to six to seven other beta cells, but not to other cell types. (wikipedia.org)

When beta-cells fail to function properly, this can lead to pathologies such as type II diabetes. (physiomeproject.org)
The first mathematical models of beta-cells were developed to describe medium bursting, and the first models to address the variability in beta-cell oscillations were developed by Chay in 1995 and 1997 (see Extracellular and Intracellular Calcium Effects on Pancreatic Beta Cells, Chay, 1997 for more details). (physiomeproject.org)
The phantom bursting model is a general paradigm for temporal plasticity in bursting in beta-cells in which bursting is driven by the interaction of two slow variables with disparate time constants (see The Phantom Burster Model for Pancreatic Beta-Cells, 2000 for more details). (physiomeproject.org)
Preptin derived from proinsulin-like growth factor II (proIGF-II) is secreted from pancreatic islet beta-cells and enhances insulin secretion. (jsurgmed.com)
In recent years, we have come to appreciate that loss or dysfunction of insulin-producing islet beta cells underlies virtually all major forms of diabetes mellitus. (medscape.com)
In type 1 diabetes , beta cells succumb to autoimmunity, leaving individuals with significantly reduced beta-cell mass and a lifelong dependence on insulin replacement therapy. (medscape.com)
Multiple strategies to replace beta cells in individuals with diabetes have been considered. (medscape.com)
This team showed that injection of just three genes- Neurog3, Mafa, and Pdx1 -into the pancreatic parenchyma of mice leads to conversion of exocrine cells to functional beta cells, a process popularly known as "reprogramming. (medscape.com)
[ 7 , 8 ] As background, in 2009, Collombat and colleagues [ 9 ] showed that pancreatic misexpression of the gene Pax4 led to the conversion of glucagon -producing alpha cells into functional beta cells. (medscape.com)
Using careful, state-of-the-art cell tracking techniques, the same group subsequently showed that Pax4 misexpression initially caused the conversion of cells lining the ducts to become alpha cells, which were then converting to beta cells. (medscape.com)

The fact that the pancreatic tissue is rich in zinc probably indicates that insulin remains stored in islet cells as a zinc salt. (biologydiscussion.com)
iii) Isolated living tissue, when perfused with sugar, shows a diminished power of burning glucose which, however, increases if insulin is added to the perfusing fluid. (biologydiscussion.com)
Our results repeatedly show that islets and encapsulated islets can be transplanted in various sites including subcutaneous tissue after pretreatment of neovascular induction. (lidsen.com)
Most recently, we found that slow release of hepatocyte growth factor (HGF) from the chitosan gel can protect islets against initial hypoxic status and subsequently induce neovascularization in subcutaneous tissue to exert islet function, eliminating the necessity for neovascularization pretreatment. (lidsen.com)
The research team then examined human pancreatic tissue from type 1 diabetics, finding strong evidence that the same process induced by caerulein also occurred in the pancreases of those individuals. (press-news.org)
Chronic relapsing pancreatitis with progressive loss of both exocrine and endocrine cells and their replacement by fibrous connective tissue results in diabetes mellitus. (merckvetmanual.com)
The exocrine hormones are released into the blood via a duct and usually cause a response to a distant organ or cell, unlike the endocrine hormones released within the tissue or the cell and enter the blood through the capillaries. (supportgroupsfornurses.org)
The most primitive endocrine systems seem to be those of the neurosecretory type, in which the nervous system either secretes neurohormones (hormones that act on, or are secreted by, nervous tissue) directly into the circulation or stores them in neurohemal organs (neurons whose endings directly contact blood vessels, allowing neurohormones to be secreted into the circulation), from which they are released in large amounts as needed.

Such disturbances seem to prevent the proper functioning of the cells in the pancreatic islet that secrete insulin and glucagon, the hormones that regulate blood sugar levels. (sciencedaily.com)
They release insulin in a highly dynamic, bi-phasic and pulsatile manner in response to elevated glucose levels in the blood ( In't Veld and Marichal, 2010 ). (frontiersin.org)
And specifically, insulin produced by β-cells lowers blood glucose, and glucagon secreted from α-cells opposes insulin action to maintain euglycemia [ 1 ] . (researchsquare.com)
Normally blood sugar adjusts the vagal tone and modifies insulin secretion. (biologydiscussion.com)
Thus, blood sugar controls insulin secretion in two ways, i.e. by direct action on the islets and through vagus. (biologydiscussion.com)
Insulin secretion runs wild in this situation and low blood sugar (hypoglycemia) becomes a problem. (vin.com)
To be meaningful in testing for insulinoma, the insulin level must be drawn when the patient's blood sugar level is less than 60 mg/dl (3.33 mmol/L) because the insulin level is interpreted in light of the blood sugar level. (vin.com)
