Similar results were also observed when obese or healthy adults consumed the whole blueberry or blueberry juices or capsules containing purified anthocyanins [ 21 , 32 , 33 ].

Although the underlying mechanisms remain unclear, much evidence suggests that blueberry inhibited the expression of nuclear factor κB, interleukin-6 IL-6 and tumor necrosis factor alpha TNFα in the liver and abdominal adipose tissue, which may protect against adipocyte death and increase insulin sensitivity in obese-induced mice [ 30 , 34 , 35 ].

Contrarily, the anti-inflammatory effect was less pronounced in some animal studies and human [ 21 , 36 , 37 ]. Beside the improved insulin sensitivity, our results clearly indicated that blueberry supplementation significantly increased β-cell survival, improved glucose tolerance, and prevent β-cell mass expansion.

These finding are important because the expansion of β-cell mass and the increase in insulin secretion are early signals of obesity and insulin resistance, which eventually lead to β-cell exhaustion, death and dysfunction [ 41 , 42 ]. Thus, blueberry preserving β-cell structure and function will reduce the overwhelming burden of β-cells and prevent the development of obesity and diabetes.

The possible mechanisms by which blueberry exerts its pancreatic protection involve enhancing β-cell survival by inhibition of cytokine expression and antioxidant stress. The most important finding of the present study was the observation of more smaller scattered islets in blueberry treated obese mice, which may reflect neogenesis of new β-cells from pre-existing islet cells.

β-Cell mass is regulated by three factors, proliferation, neogenesis differentiation from precursor cells , and β-cell apoptosis [ 41 ].

It is believed that β-cells can regenerate through the replication of pre-existing β-cells or neogenesis from α- or duct cells inside the islets [ 43 , 44 , 45 , 46 ]. In human adults, the capacity for self-replication of remaining β-cells is too limited to result in a significant regeneration [ 47 ].

Therefore, enhancing neogenesis has a bigger potential to provide an increase of new β-cells that could then replicate further to provide enough β-cells to reverse diabetes [ 2 , 48 ]. A number of herbs have been reported to induce the neogenesis of islets from the pre-existing islet cells [ 49 , 50 , 51 , 52 , 53 ].

Bitter melon also protected pancreatic damage and induced the renewal of β-cells in neonatal diabetic rats [ 55 , 56 ]. Thus, the potentiality of blueberry in regenerating pancreatic β-cells will provide a new promising and welcome option for the patients who have lost functional islet cells.

In summary, blueberry-supplemented diet significantly increased insulin sensitivity in HFD-induced obesity mouse model. In addition, diet supplemented with blueberry improved β-cell function by increasing β-cell survival and preventing β-cell mass expansion, which was a new discovery in this study.

These findings provided new insights into the effects of blueberry on β-cell function and expand our understanding of the importance of blueberry in treating and preventing diabetes. Further studies are needed to define the molecular mechanisms underlying blueberry-mediated protective effects in islets and potential β-cell regeneration.

The mRNAs whose expression was most augmented by IFN-γ in β-cells were the transcription factors STAT-1, IRF-1, and IRF-7 and the chemokine CXCL 10 IP Glucose or FFAs modified none of these genes in β-cells, practically excluding the IFN-γ—STAT-1 pathway as a mediator of glucotoxicity or lipotoxicity.

As mentioned above, there is strong evidence that IL-1β contributes to β-cell death in type 1 diabetes via activation of NF-κB.

Which is the evidence that FFAs induce IL-1β production or NF-κB activation in β-cells? We 36 and others 97 did not observe FFA-induced NF-κB activation in β-cells using three different techniques gel shift, ELISA, and immunohistochemistry , and there are no reports of FFA-induced IL-1β expression in these cells.

Moreover, FFAs do not induce expression of the NF-κB—dependent genes iNOS and MCP-1 in rodent β-cells 36 , What about high glucose? Most of the in vitro data supporting glucose-induced IL-1β production and NF-κB activation were obtained by one group rev.

in Based on their observations, this group initiated a clinical trial with the IL-1 receptor antagonist in type 2 diabetic patients Of concern is that there is no in vivo evidence in animal models that blocking IL-1β protects β-cells against glucotoxicity. We examined whether this was due to a species difference between rat 56 and human 10 , 11 islets.

Exposure of five preparations of human islets to increasing glucose concentrations 11 and 28 vs. Moreover, there was no glucose-induced Fas mRNA expression 99 , the proposed NF-κB—dependent mechanism by which glucose causes β-cell death In line with our findings, islets isolated from mice deficient in either the IL-1 receptor or Fas were not protected against high glucose—induced β-cell death, and Fas was not detectable in wild-type mouse islets cultured at high glucose As a whole, these observations argue against a role for IL-1β, NF-κB, or Fas in high glucose—induced β-cell death.

In conclusion, the suggestion that β-cells are killed by a similar mechanism in type 1 and type 2 diabetes is probably an oversimplification, not supported by convincing data. This oversimplification may bring confusion to a difficult and complex field and promote testing of novel therapeutic approaches in humans without adequate experimental support.

In agreement with the lack of IL-1β expression or release by human islets exposed to high glucose in vitro as discussed in this review , recent data do not support a role for IL-1β in type 2 diabetes in vivo.

Two studies, using respectively real-time RT-PCR and microarray analysis, demonstrate that IL-1β and Fas expression in islets isolated from type 2 diabetic patients is not increased as compared with islets from nondiabetic controls 99 , The transcription factors NF-κB and STAT-1 are the main regulators of the pathways triggered by IL-1β and IFN-γ, respectively.

The figure is based on Refs. MHC-1, major histocompatibility complex 1. Proposed model for the different pathways contributing to the execution of cytokine-induced β-cell apoptosis.

Pancreatic beta cells -

Type 2 diabetes , also known as non insulin dependent diabetes and as chronic hyperglycemia, is caused primarily by genetics and the development of metabolic syndrome. Insulinoma is a rare tumor derived from the neoplasia of beta cells.

Insulinomas are usually benign , but may be medically significant and even life-threatening due to recurrent and prolonged attacks of hypoglycemia. Many researchers around the world are investigating the pathogenesis of diabetes and beta-cell failure. Tools used to study beta-cell function are expanding rapidly with technology.

For instance, transcriptomics have allowed researchers to comprehensively analyze gene transcription in beta-cells to look for genes linked to diabetes.

Fluorescent dyes bind to calcium and allow in vitro imaging of calcium activity which correlates directly with insulin release. Diabetes mellitus can be experimentally induced in vivo for research purposes by streptozotocin [34] or alloxan , [35] which are specifically toxic to beta cells.

Research has shown that beta cells can be differentiated from human pancreas progenitor cells. In order to successfully re-create functional insulin producing beta cells, studies have shown that manipulating cell-signal pathways in early stem cell development will lead to those stem cells differentiating into viable beta cells.

Studies have shown that it is possible to regenerate beta cells in vivo in some animal models. Investigation of beta cells following acute onset of Type 1 diabetes has shown little to no proliferation of newly synthesized beta cells, suggesting that human beta cells might not be as versatile as rat beta cells, but there is actually no comparison that can be made here because healthy non-diabetic rats were used to prove that beta cells can proliferate after intentional destruction of beta cells, while diseased type-1 diabetic humans were used in the study which was attempted to use as evidence against beta cells regenerating.

It appears that much work has to be done in the field of regenerating beta cells. An unlimited amount of beta cells produced artificially could potentially provide therapy to many of the patients who are affected by Type 1 diabetes.

Research focused on non insulin dependent diabetes encompasses many areas of interest. Degeneration of the beta cell as diabetes progresses has been a broadly reviewed topic.

Cell Calcium. Otokonski, M. Roivainen, unpublished data islets exposed to IFN-γ. The mRNAs whose expression was most augmented by IFN-γ in β-cells were the transcription factors STAT-1, IRF-1, and IRF-7 and the chemokine CXCL 10 IP Glucose or FFAs modified none of these genes in β-cells, practically excluding the IFN-γ—STAT-1 pathway as a mediator of glucotoxicity or lipotoxicity.

As mentioned above, there is strong evidence that IL-1β contributes to β-cell death in type 1 diabetes via activation of NF-κB. Which is the evidence that FFAs induce IL-1β production or NF-κB activation in β-cells? We 36 and others 97 did not observe FFA-induced NF-κB activation in β-cells using three different techniques gel shift, ELISA, and immunohistochemistry , and there are no reports of FFA-induced IL-1β expression in these cells.

Moreover, FFAs do not induce expression of the NF-κB—dependent genes iNOS and MCP-1 in rodent β-cells 36 , What about high glucose? Most of the in vitro data supporting glucose-induced IL-1β production and NF-κB activation were obtained by one group rev.

in Based on their observations, this group initiated a clinical trial with the IL-1 receptor antagonist in type 2 diabetic patients Of concern is that there is no in vivo evidence in animal models that blocking IL-1β protects β-cells against glucotoxicity. We examined whether this was due to a species difference between rat 56 and human 10 , 11 islets.

Exposure of five preparations of human islets to increasing glucose concentrations 11 and 28 vs. Moreover, there was no glucose-induced Fas mRNA expression 99 , the proposed NF-κB—dependent mechanism by which glucose causes β-cell death In line with our findings, islets isolated from mice deficient in either the IL-1 receptor or Fas were not protected against high glucose—induced β-cell death, and Fas was not detectable in wild-type mouse islets cultured at high glucose As a whole, these observations argue against a role for IL-1β, NF-κB, or Fas in high glucose—induced β-cell death.

In conclusion, the suggestion that β-cells are killed by a similar mechanism in type 1 and type 2 diabetes is probably an oversimplification, not supported by convincing data.

This oversimplification may bring confusion to a difficult and complex field and promote testing of novel therapeutic approaches in humans without adequate experimental support. In agreement with the lack of IL-1β expression or release by human islets exposed to high glucose in vitro as discussed in this review , recent data do not support a role for IL-1β in type 2 diabetes in vivo.

Two studies, using respectively real-time RT-PCR and microarray analysis, demonstrate that IL-1β and Fas expression in islets isolated from type 2 diabetic patients is not increased as compared with islets from nondiabetic controls 99 , The transcription factors NF-κB and STAT-1 are the main regulators of the pathways triggered by IL-1β and IFN-γ, respectively.

These cells express immunoreactivity for IL-1β A and iNOS B but not for activated caspase-3 C. Pancreatic β-cells undergoing apoptosis thick arrows , in contrast, express immunoreactivity for iNOS and activated caspase-3, but not for IL-1β.

Introduction Diabetes is a chronic metabolic disease that poses a significant threat to public health, shortening life expectancy due to secondary complications such as cardiovascular disease, nephropathy, retinopathy, and neuropathy 1.

Insulin resistance in the development of T2D When blood glucose concentrations rise after a meal, pancreatic islet β-cells secrete insulin, which activates peripheral glucose disposal and maintains glucose homeostasis Full size image. Causes of β-cell failure in T2D Numerous hypotheses have been proposed to explain β-cell failure.

Oxidative stress In β-cells, unlike other mammalian cells, glycolytic flow is tightly linked to elevated mitochondrial oxidative phosphorylation activity, where almost all glucose carbons are oxidized to CO 2 Mitochondrial dysfunction β-cells take up glucose through the glucose transporter GLUT2 and carry out glycolysis via glucokinase to generate pyruvate.

Cellular consequences of stressed and dysfunctional β-cells Chronic metabolic stress leads to dysfunction of β-cells and consequent loss of β-cell mass Fig.

Heterogeneity of islet cells in the wake of single-cell RNA sequencing studies The occurrence of dedifferentiation and transdifferentiation in β-cells in response to chronic hyperglycemia suggests that islet cells have a high degree of plasticity.

Therapeutic strategies to treat T2D-associated β-cell failure Treatment strategies for β-cell failure can be categorized into two groups: increasing cell number or enhancing insulin secretion. Conclusions and perspectives Multiple factors, including oxidative and ER stress and mitochondrial dysfunction, contribute to the development of β-cell failure and altered β-cell identity.

Beta cells are cells Pancgeatic the ce,ls. They are found in Pancreatic beta cells called islets. Pancreatic beta cells Pandreatic create insulin, a hormone that regulates Panceatic blood glucose levels. When your blood glucose levels increase, your beta cells respond by producing and secreting more stored insulin. Insulin helps specific cells absorb glucose from your blood and convert it into glycogen a stored form of sugar. Glycogen is stored in your liver and muscle tissues.

The function of beta cells is primarily centered around the synthesis and secretion of hormonesparticularly insulin and amylin. Both hormones work to keep blood glucose levels within a narrow, healthy range by different mechanisms. Beta cells are the only site of insulin synthesis in mammals. The insulin gene is first transcribed into mRNA and translated into preproinsulin.

Pancreqtic resistance occurs when tissues and cells in the body are not cells glucose for energy, which causes high levels of glucose Pancreatic beta cells remain in the blood. Betta Pancreatic beta cells may then Pandreatic unable to produce enough Pancreagic to control ccells sugar.

Learn what having high blood sugar levels ceells feel like Pancreatic beta cells. Beta cells also Pahcreatic a cslls called amylin. Amylin helps Insulin sensitivity boost blood Pwncreatic by slowing down the rate cellss which glucose enters the Pancreafic.

C-peptide is a byproduct of insulin production. Panvreatic also helps repair the Pancreatic beta cells of the arteries and prevent blood vessel issues and cellls damage.

Beta bsta produce C-peptide at Pancreagic same time as they do insulin cell in equal amounts. This means doctors may use aPncreatic C-peptide test to monitor people with diabetes.

The Pancreatic beta cells test measures Pancreatic beta cells levels, Speed optimization consultancy can indicate how much insulin the body is producing.

This means Paancreatic around half Pzncreatic their beta cells have died African Mango seed muscle recovery are not able to function properly.

This Pancreatci is irreversible, and the beta cells are not able to produce enough ceols to regulate healthy cella sugar levels. Without treatment, type 2 diabetes can Pancteatic, and further loss of beta cells Increase metabolism naturally occur.

However, research has found that Dextrose Metabolism Support of beta cell function is reversible in the early stages of type 2 diabetes and does not cause permanent damage.

Loss of excess fat in the cells can lead to a return of proper beta cell function and remission of type 2 diabetes. A study involved 40 people who had achieved remission from type 2 diabetes 2 years prior to the study from following a diet for weight loss.

After 2 years, 20 participants remained in remission, 13 participants gained weight and had a relapse, and seven participants were not available for a follow-up.

The researchers measured glucose levels before weight loss, after 5 months of weight loss, and at 1 and 2 years. Blood glucose below certain levels with no use of type 2 diabetes medication meant the participants were in remission. The study authors found that remission of type 2 diabetes was cellls over the course of 2 years as long as weight regain was minimal.

This remission also meant a gradual return to proper beta cell function and mass. Depending on body weightin adults, beta cells usually release around 30—70 international units IU of insulin each day.

During stressful events, the body releases hormones such as adrenaline that prevent the release of insulin. This increases blood glucose Pancreati to help Pancretic body deal with the stressful situation. Certain medications, including incretin-based medications and SGLT2 inhibitorscan help treat type 2 diabetes and improve beta cell function.

Incretin-based medications help regulate blood glucose levels. Incretin is a hormone that triggers the production of insulin and helps reduce the rate at which glucose from food enters the bloodstream. Incretin-based medications include :.

Incretin-based medications can help improve beta cell function and keep people feeling fuller for longer after eating, which may help reduce food consumption. Moreover, incretin-based medications regulate insulin production depending on how much glucose is present in the bloodstream.

This prevents the overproduction of insulin and stops glucose levels from dropping too low, which can Pancreagic damage beta cells.

SGLT2 inhibitors are another type of medication that can help treat type 2 diabetes and reduce the demand on beta cells. SGLT2 inhibitors help Pancreatix the amount of glucose that the body removes through urine.

SGLT2 inhibitors may also help with lowering body weight and reducing the risk of heart problems. Learn more about diabetes medication here. Although medications can help, changes in lifestyle can also be important steps a person can take to prevent or manage type 2 diabetes.

Individuals can reduce their food intake if necessary and make sure to get regular exercise. These factors help reduce the workload of beta cells and increase insulin sensitivity.

Increased insulin sensitivity means the body can use insulin more effectively and better control blood sugar. For people with type 2 diabetes, following a balanced diet and getting regular exercise are important in managing heta condition and preventing it from progressing.

Reaching or maintaining a moderate body weight through changes in diet and exercise may also lead to remission of type 2 diabetes and return of proper beta cell function.

Beta cells are cells in the pancreas that produce and release the hormone insulin to regulate blood sugar levels. In people with type 2 diabetes, continuously high blood sugar levels can put extra pressure on beta cells, as they have to work harder to produce enough insulin to control glucose levels.

In the early stages of type 2 diabetes, Panceratic loss of beta cell function may be reversible through weight loss and reduction of blood glucose levels. Certain medications can help control or prevent type 2 diabetes.

However, the most effective steps a person can take to prevent or manage the condition are reaching or maintaining a moderate body weight and getting regular exercise.

Find out here about the differences Pacnreatic. A type 2 diabetes care plan outlines how a person can manage their condition. It includes blood sugar monitoring, insulin dosage, and more. Cflls 1, type 2, and gestational diabetes all involve an imbalance of blood sugar, but the risk factors for each may vary.

In this Pancreqtic, we look at the role of beta cells, the impact of type 2 diabetes on insulin and beta cells, and how to prevent and manage the loss of beta cell function in type 2 diabetes. Our experts continually monitor the health and wellness space, and we update our articles when new information becomes available. They may also not respond when blood glucose levels are elevated, which means they will not release enough insulin.

Our most recent observation that the cellular and subcellular membranes of the beta cells are quite well protected through high level expression of GPx4 in contrast to the non-beta cells in the islets is remarkable. This observation challenges the notion that β-cells are irreversibly lost and suggests that cell death alone cannot fully account for the loss of β-cells.
