There are approximately 180 million people worldwide who have diabetes and 2.5 million of these live in the UK. Diabetes can be successfully managed, but it is a chronic disorder which currently does not have a cure.
Type 1 diabetes is an autoimmune disease and accounts for up to 10% of diabetes cases in the UK.
The risk of developing type 1 diabetes has recently been linked with genetic factors and may be associated with lifestyle factors such as diet and exercise. Type 1 diabetes is treated by insulin injections alongside a healthy diet and regular exercise.
Type 2 diabetes is a disorder that is increasing in both developed and developing nations as unhealthy diets and lifestyles become more common. Many factors influence the development of type 2 diabetes; such as an inherited predisposition to diabetes and diets high in saturated fats, sugar and low in fibre.
Regular meals with foods that contain starch (bread, pasta, potatoes and rice) and decreased consumption of processed foods to maintain a stable blood sugar level. Recent research has shown that it is possible to prevent diabetes in some people who are at high risk of developing the disease.

Conclusion This means that multifactorial or “global” treatment to reduce the risk of vascular complications must now be the standard of care! Women who go through the menopause earlier or later than average are at greater risk of type 2 diabetes, doctors have warned. The link is particularly strong for an early menopause, with those who have their last period before the age of 46 being 25 per cent more likely to develop the condition in later life. However, those with a late menopause – defined as having their last period aged 55-plus – are also at heightened risk.
It is thought the results for early menopause can be blamed on lack of exposure to oestrogen. These women are 12 per cent more likely to develop the condition than those who go through menopause in their late 40s or early 50s.
The discovery is important because type 2 diabetes, the form that usually strikes in middle-age and is fuelled by obesity, is becoming ever more common as waistlines expand. It eats up a tenth of the NHS’s budget and leads to disabling and life-threatening complications from stroke and heart attacks, to blindness and circulatory problems that lead to limbs being amputated. Knowing more about who is at risk could have massive benefits to health and to the economy.
The US researchers analysed data on almost 125,000 post-menopausal women aged between 50 and 79.
Information included when they had their first and last period, as well as height, weight and medical history.
Twelve years later, cases of the condition were more common in women with an early or late menopause. The length of a woman’s ‘reproductive span’ – the number of years between her first and last period, was also important.
Those with reproductive span of under 30 years – suggesting late puberty and early menopause – were 37 per cent more likely to develop diabetes than those who were fertile for the typical 36 to 40 years.
Similarly, women who were fertile for longer than average, had 23 per cent higher odds of diabetes.
Low levels of the female sex hormone oestrogen are known to fuel appetite and are linked to high blood sugar levels – a symptom of diabetes. Oestrogen levels plunge at menopause, and women who go through menopause early will be exposed to less of it over their lives.
Just why those with a late menopause are also at heightened risk is unclear, Menopause, the official journal of the North American Menopause Society reports. Lead researcher, Dr Erin LeBlanc, of the Kaiser Permanente Center for Health Research in Oregon, said: ‘Our study suggests the optimal window for menopause and diabetes risk is between the ages of 45 and 55. Women who have their ovaries removed to reduce the risk of cancer have a greater risk of dementia, research suggests. The operation, which triggers early menopause, results in a reduction in memory and thinking skills, scientists have found. Experts fear this may eventually lead to early-onset dementia for many women, and may even lead to Alzheimer’s.
But taking hormone replacement therapy (HRT) pills may halt this cognitive decline, according to findings presented at the Alzheimer’s Association International Conference in Toronto. Nearly 4,000 women undergo surgery to extract their ovaries in Britain each year, many of them to lower their chance of developing ovarian cancer later in life.
But ovarian removal triggers immediately brings on the menopause, as the body’s method for producing the oestrogen hormone is removed. Dr Gillian Einstein of Toronto University, an expert in the way dementia hits women, said oestrogen has a protective impact on the connections in the brain – and when natural hormone production stops this protection disappears.

These cells release their products directly into the blood and so are a form of endocrine gland. People with type 1 diabetes are usually required to take either two or four injections of insulin every day.
It develops when the body can still make some insulin but not enough, or when the insulin that is produced does not work properly (known as insulin resistance). It typically develops in the over 40's and can be treated using combinations of lifestyle changes (diet and exercise), oral medicines and daily, long acting, insulin injections.
For example, individuals in the Finnish Diabetes Prevention Study took part in an intensive lifestyle programme focussed on changing diet and physical activity behaviour.


It causes the liver to convert glycogen back to glucose and to release glucose into the bloodstream. It is active in controlling blood glucose levels as it allows cells in the body to take in and store glucose.

This leads to the rapid onset of the symptoms of diabetes, including fatigue, unquenchable thirst, weight loss and the production of large volumes of urine. Abdominal fat cells release fatty acids into the blood that stimulate the liver to release glucose and triglycerides.

SCFAs have no such transport system and are directly taken up by the body’s cells and are favoured by gut cells and brain cells. These are only a very few of the hundreds of known inborn errors of metabolism. Advances in the diagnosis and treatment of inborn errors of metabolism have improved the outlook for many of these conditions so that early diagnosis, if possible in infancy, can be helpful. The development of pancreatic endocrine cells starts with an early endocrine progenitor and ends with mature hormone-producing islet cell types. The schematic shows the differences in culture methods to produce IPCs from murine ESC (top) and human ESC (bottom). IntroductionDiabetes mellitus is a chronic metabolic disease that results in high levels of glucose in the blood. This process is therefore increased in overweight people with greater numbers of abdominal fat cells.

Eggerichs also understands the power of habits or cycles which can perpetuate themselves over long periods of time. Insulin resistance is a risk factor for developing heart disease and type 2 diabetes, the most common form of diabetes. Cell surface markers (noted above the cell types) and gene expression (in italics) in distinct pancreatic cell lineages are shown. Normally, glucose is transported into cells from the blood for energy, and this transport is initiated in response to the hormone, insulin.
Insulin injections for type 2 diabetes: One insulin injection each day can be used to substitute the use of diabetes pregnancy first trimester diabetes pills for some people while others might require both an insulin injection and diabetes pills. It’s used at least a dozen times a month and I hope that it’ll keep going for a few more years yet!
In diabetic patients, cellular glucose uptake is defective, in part due to the inability of cells to respond to insulin, or the inability of the body to produce the insulin itself.
In this thesis different aspects of continuous intraperitoneal insulin infusion (CIPII) as an option for intensive insulin therapy in T1DM were investigated.
Limited Home monitoring may still be worthwhile to check how good (or otherwise) your control is. Since this mineral assists in the production of insulin it helps to stabilize blood sugar levels and can be beneficial both for people with hypoglycemia and diabetes.
Type 2 diabetes is more common than type 1 diabetes accounting for 85-95% of people with diabetes. It is an especially challenging health problem, as treatments to both control hyperglycemia as well as the debilitating side effects of diabetes, such as injury to the blood vessels and nerves, must be addressed.
Amongst the three types of diabetes (Type I - autoimmune, gestational and Type II – adult onset), Type II diabetes is the most prevalent, in which hyperglycemia is uncontrolled due to the body’s inability to produce enough insulin or due to the body’s inability to respond appropriately to lower the blood glucose level. In contrast, in patients with Type I diabetes (TID), insulin-producing beta (?) cells are destroyed by the immune system. Studies of TID by many groups have provided extensive insight to the fields of immunological tolerance and pancreatic developmental biology. In this chapter, we will briefly describe TID, provide a synopsis of pancreatic ? cell development in mice as compared to humans, review of some of the medical treatments currently available for TID, and discuss current studies that have explored the use of stem cells as alternative possible therapies for TID. TID in humansA fully comprehensive comparison of TID in humans and mice has recently been published, so we will only highlight certain areas (van Belle, Coppieters et al. TID is a multigenic disease, and several candidates have been discovered that implicate disruptions in the normal process of negative selection of autoreactive T cells during thymic development, genetic association with specific major histocompatibility complex (MHC) genes in the human leukocyte antigen (HLA) locus, as well as dysregulation of mature T lymphocyte responses.
For example, patients with mutations in the FoxP3 or Aire genes, which are important for the development and function of regulatory T cells (Tregs) and expression of “self-antigens” by medullary thymic epithelial cells, often present with autoimmune diabetes, as well as other autoimmune disorders (Michels and Gottlieb 2010).
On the other end of the spectrum, the inability to downregulate or prevent mature T cell responses due to mutations in cytokine receptor expression (Garg, Tyler et al. 2011) can also result in sustained T cell cytotoxicity or lack of Treg response towards diabetes-related antigens. TID in miceThe identification of the mechanisms underlying the autoimmunity of TID in humans has been facilitated by the use of rodent models of the disease (Van Belle, Taylor et al. Despite the fact that TID is a multigenic disease with heterogeneous etiologies, there is overall consensus that TID is caused by the destruction of pancreatic ? cells by sets of immune cells that recognize many potential autoantigens (such as insulin, glutamate decarboxylase (GAD), islet antigens, and heat shock proteins-60 and -70) and that the disease can be transferred by the transplantation of autoreactive T lymphocytes that are specific for these antigens (Mallone, Brezar et al. Several spontaneous, induced and transgenic mouse models currently exist, which have provided important insights into the genetics, cellular mechanisms and immunological aspects of TID.
However, the non-obese diabetic (NOD) mouse strain remains the primary animal strain for studies of TID. The utility of the NOD mouse and comparison of the TID in the NOD mouse with human TID have been extensively reviewed and debated, and we direct the reader to these excellent reviews for further reference (Anderson and Bluestone 2005; Roep and Peakman 2011). The NOD mouse strain, when housed in specific-pathogen free conditions, displays the onset of diabetes after 12 weeks of age in both sexes. Insulitis is observed as mononuclear infiltration in the islets before full blown diabetes is evident, and this cellular infiltrate is comprised of primary T lymphocytes, but other lymphoid and myeloid cells are also present.
The insulitis results in the destruction of the pancreatic islets and the insulin-producing ? cells.
The NOD mouse also displays defects in functional macrophages and natural killer cells, NKT cells and regulatory T cells and complement. The NOD mouse, therefore, has allowed for the investigation of numerous immune mechanisms that contribute to the development of TID. The peripheral neuropathy that accompanies TID in humans is also evident in the NOD mouse, which has allowed for analysis and management of the side effects of TID (Anderson and Bluestone 2005; Roep and Peakman 2011). Similar to human diabetes, the MHC of the NOD mouse contains several loci that are linked to increased susceptibility to TID. Despite the similarities between TID in humans and in the NOD mouse, clear differences have been noted.


TID in the NOD mouse appears to be a more aggressive disease compared than that in humans, so the NOD mouse may be more beneficial for studies of therapies for long-term TID than for discovery of pre-susceptibility markers of TID. ? cells in the NOD mouse may also be more proliferative and could possibly regenerate better than other strains (Sherry, Kushner et al.
2006), and evidence that pancreatic development is altered in the NOD mouse also exists (Homo-Delarche 2001).
Therefore, in addition to its clear autoimmune etiology, TID may also result from defects in pancreatic development.
Pancreatic development in the mouse and humanThe adult pancreas organ is comprised of many cell types, including exocrine and endocrine cells, and is highly vascularized. Although TID is a disease that occurs in the fully formed pancreas, strategies to treat or cure TID via ? cell regeneration or ? cell differentiation from embryonic stem cells (ESCs) or induced pluripotent cells (iPSCs) have relied on the current knowledge of pancreatic development during the fetal period. Here, we briefly review the development of pancreas in the mouse and human, and then move to a description of development of ? cells only. In the first phase, pancreatic formation from the endodermal gut tube begins at embryonic day (e) 8.5.
Patterning of the gut tube in the pancreatic region is reliant on retinoic acid (RA) signaling from the mesoderm. The dorsal and ventral pancreas buds form from the pancreatic epithelium in the primitive gut tube. Recently, the critical role of the Wnt signaling in the pancreatic mesenchyme in the differentiation of pancreatic epithelial cells was shown in vivo (Landsman, Nijagal et al. Eventually, the ventral pancreas rotates toward the dorsal pancreas, and they fuse into one organ by e12.5. In the second phase (e13.5), the cells within the immature pancreas begin to differentiate into exocrine cells that are required for the production of digestive enzymes, and endocrine cells that secrete hormones into the blood, such as glucagon, insulin, somatostatin, pancreatic polypeptide and ghrelin. Each of these hormones is produced by a distinct endocrine cell type (with insulin produced by the ? cells) (Figure 1). The third phase of pancreatic development occurs after birth, and is associated with the ability of the pancreas to respond to dietary intake and maintain glucose homeostasis.Islet development in humans occurs at a slower rate compared to what is observed in mice, but the reasons for this are not understood. The size of the human islet is comparable to that of the mouse, but in the mouse, the mean area ratio of ? cells is higher than observed in the human (Kim, Miller et al. Fetal antigen-1 is a protein expressed exclusively in human endodermal tissue and pancreatic epithelial cells before islet formation (Tornehave, Jansen et al. Islets can be located in the human fetus as early as 12-13 weeks post coitus (Piper, Brickwood et al. 2004), although functional ? cells that are insulin-positive can be detected as early as 8 weeks. The existence of the self-renewing pancreatic stem cell is still controversial.An overview of pancreatic endocrine cell development is shown in Figure 1. Definitive endodermal progenitor cells can differentiate into pancreatic progenitor cells, which have been identified by the expression of two critical transcriptional factors: Pdx1 and neurogenin 3 (Ngn3). Experiments with conditional Pdx1 transgenic reporter mice (inducible Cre-ERTM-LoxP system to mark the progeny of cells that express Pdx1) demonstrated that Pdx1+ cells give rise to all three types of pancreatic tissue: exocrine, endocrine and duct (Gu, Dubauskaite et al. In line with this, Pdx1 deficiency in mouse and humans leads to a complete pancreas agenesis at birth (Ahlgren, Jonsson et al. Pdx1 is also a critical transcriptional activator of insulin and somatostatin in adult islet cells (Ohlsson, Thor et al. Similar to Pdx1, Ngn3+ cells give rise to all islet lineage cells during embryogenesis (Gradwohl, Dierich et al. Although some have reported that Ngn3 is undetectable in adult pancreas (Gradwohl, Dierich et al.
2007), Ngn3+ cells in duct-ligated adult pancreas were detected and observed to differentiate into islet cells (Gu, Dubauskaite et al.
Beta cells in the human, like in the mouse, are derived from a heterogeneous population of pancreatic progenitor cells (Scharfmann, Xiao et al.
Pax4 (paired box 4) is required for the commitment to the pancreatic lineages (Wang, Elghazi et al. 2004), as well as for the regulation of ? cell mass size, proliferation and survival in mice (Brun and Gauthier 2008), and mutations in the Pax4 gene have been linked to susceptibility to both Type I and Type II diabetes in humans (Yokoi, Kanamori et al. In addition, both human and mice insulinoma cells overexpress Pax4 in comparison to mature ? cells, suggesting that Pax4 may also play a role in ? cell proliferation and resistance to apoptosis.
Nkx6.1 functions exclusively in ? cells and is required for ? cell development and specification, control of insulin secretion after glucose challenge, and can also induce human and rat ? cell proliferation (Schisler, Fueger et al. However, in vivo overexpression of Nkx6.1 does not have any effect on ? cells in the mouse (Schaffer, Yang et al.
Current therapies for TIDA fully mature, functional ? cell produces and appropriately secretes the mature form of insulin (i.e. The current treatment for TID is long-term insulin replacement therapy that is delivered via injection, insulin pens or pumps, and has been quite successful for control of hyperglycemia.
However, insulin replacement therapy is not considered a cure for TID, as patients receiving insulin long-term still manifest abnormalities in metabolism, as measured by above-normal levels of glycated hemoglobin (HbA1c). Furthermore, for children, the daily requirement for insulin replacement can limit their day-to-day activities, and TID-related complications, such as vascular disease, retinopathy and neuropathy, still persist even with insulin therapy.
Pancreatic transplantation has been performed for TID patients with success, but the main limitations of this strategy are the low number of suitable donors required for transplant and the decision if the risks of surgery and transplantation outweigh the benefits (Jahansouz, Kumer et al. Furthermore, even with insulin replacement therapy or pancreatic transplantation, autoreactive immune cells that can attack and destroy any residual ? cells in the patient can still remain. For this reason, therapies that modulate the immune response to ? cells and ? cell antigens also exist, and their safety and efficacy have been or are currently being tested in clinical trials (Bluestone, Herold et al.
GAD65 specific-antigen-based immunotherapy with alum adjuvant demonstrated preservation of C-peptide fasting levels in younger new-onset patients four years after treatment (Ludvigsson, Hjorth et al. Humanized anti-CD3 antibody (in which human Fc immunoglobulin domains are engineered to mouse CD3-binding portions of the antibody) therapy given in a single dose reduced the decline of insulin production and the amount of exogenous insulin required in the patients (Herold, Gitelman et al. Interestingly, the anti-CD3 antibodies reduced the numbers of circulating T lymphocytes, but whether or not autoreactive T cells are specifically depleted is unclear. There is evidence that the anti-CD3 antibody acts as a weak TCR agonist and stimulates the production of regulatory T cells (Tregs) in humans. B lymphocytes in TID have been postulated to act as antigen-presenting cells and also to produce autoantibodies that can result in ? cell destruction (Bluestone, Herold et al. Anti-CD20 antibodies target and deplete B lymphocytes, and lead to a preservation of ? cell function in patients, as measured by C-peptide production and reduction of HbA1c levels compared to controls. However, the level of autoantibodies in these TID patients was not determined, so the mechanism by which anti-CD20 therapy works in TID patients is still uncertain. As we will explain further below, these immune modulation therapies may also be important for the future success of ? cell regeneration and transplantation.
Experimental alternative treatments for TID: Stem cellsPancreas transplantation has succeeded as a replacement for insulin-secreting ? cells for TID patients, but this relies on a limited source of cadaveric pancreatic tissue (Danovitch, Cohen et al. Early studies demonstrated that isolated human islets did not proliferate in suspension culture, and that adherent islet cells showed limited replication of ? cells (Nielsen, Brunstedt et al. Therefore, alternative sources of IPCs are needed, and stem cells have been suggested as this source. Stem cells are undifferentiated cells that are capable of self-renewal and differentiation into any cell type. Embryonic stem cells (ESCs) are derived from the inner cell mass of implanted embryos (Evans and Kaufman 1981), induced pluripotent stem cells (iPSCs) are adult or fetal cells that have been “reprogrammed” to an ESC-like state (Takahashi and Yamanaka 2006), adult stem cells are isolated from adult tissues (Becker, Mc et al. 1963) and germline-derived stem cells are generated from embryonic or adult gonads (Shamblott, Axelman et al. Tissue-specific pancreatic stem cellsThe existence of pancreatic stem cells was proposed in the last decade (Ramiya, Maraist et al. For example, pancreas from pregnant rats and mice displayed an uptake of bromodeoxyuridine (BrdU) during pregnancy, suggesting the proliferation of islets (Parsons, Brelje et al. 1999; Rieck and Kaestner) that reduced expression of multiple endocrine neoplasia type 1 (MEN1), a tumor suppressor (Karnik, Chen et al. 2007), and enhanced expression of tryptophan hydroxylase 1 (Tph1), which allows for incorporation of BrdU in the cell (Kim, Toyofuku et al. In addition, expression of Ki-67 (a marker associated with proliferation) and ?-cell mass increase has been described in the pancreas of obese mice, perhaps as a response to insulin resistance (Butler, Janson et al.
Other authors have shown that mature ? cells are capable of self-replication (Figure 2), and that this is the mechanism by which new beta cells in the adult are generated.
Young diabetic rats are able to regenerate ? cells after streptozotocin (STZ)-induced ? cell destruction, but this capacity for regeneration declines rapidly during the first days of life (Wang, Bouwens et al.
More recently, human islet precursor cells were identified from IPCs that underwent an epithelial-to-mesenchymal transition, demonstrating that, in vitro, human IPCs from the islets of cadaveric pancreas donors could spontaneously produce highly proliferative “de-differentiated” fibroblast-like cells that could then possibly be expanded and later re-induced into insulin-producing, ?-like cells (Gershengorn, Hardikar et al.
As mentioned previously, Pdx1 and Ngn3 are two transcription factors which are essential for endocrine cell differentiation during pancreas development, and have been targets in the search of pancreatic stem cells. However, it has not been demonstrated if Pdx1+ cells can self-renew (Jiang and Morahan 2011), a requirement for stem cell definition. Ngn3+ cells from duct-ligated adult pancreas can develop into islet cells (Xu, D'Hoker et al. However, Ngn3 expression in the embryo inhibits proliferation by inducing cyclin-dependent kinase inhibitor 1a (Cdkn1a) (Miyatsuka, Kosaka et al.
