Previous research has suggested that after menopause , women may face a greater risk of type 2 diabetes. This has been attributed to hormonal changes, such as a reduction in estrogen levels. Following on from such studies, scientists have investigated whether or not estrogen replacement therapy could help to prevent type 2 diabetes among postmenopausal women, and many studies have produced positive results.

That being said, the exact mechanisms by which estrogen may protect against type 2 diabetes have been unclear — until now.

While previous studies have primarily focused on how estrogen affects the insulin-producing cells of the pancreas, this latest study also looked at how the hormone impacts cells that produce glucagon, which is a hormone that increases blood glucose.

Diabetes is therefore due to an imbalance between these two hormones controlling the sugar level in the blood. The new study revealed that the alpha cells of the pancreas, or cells that secrete glucagon, are highly sensitive to estrogen; the hormone causes them to release less glucagon, but more of a hormone called GLP1.

And, notably, GLP1 is also released by the intestine after eating; it encourages inulin secretion, blocks glucagon secretion, and increases feelings of fullness. Hormone replacement therapy has been associated with a number of health risks for women who are postmenopausal, such as a greater risk of cardiovascular disease.

However, he adds that undergoing estrogen replacement therapy for only a few years shortly after menopause does not appear to raise cardiovascular risk. It could also help to reduce the risk of type 2 diabetes. Researchers have found that adopting a vegan diet has the potential to prevent type 2 diabetes in people who are overweight or obese.

Medications for type 2 diabetes reduce blood sugar levels to prevent symptoms and complications. Read about types of drugs, other treatments, and more. Breakthrough research shows that type 2 diabetes occurs when fat from the liver overspills into the pancreas and confirms that weight loss can reverse….

The release of glucagon is stimulated by low blood glucose, protein -rich meals and adrenaline another important hormone for combating low glucose. The release of glucagon is prevented by raised blood glucose and carbohydrate in meals, detected by cells in the pancreas.

For example, it encourages the use of stored fat for energy in order to preserve the limited supply of glucose. A rare tumour of the pancreas called a glucagonoma can secrete excessive quantities of glucagon.

This can cause diabetes mellitus, weight loss, venous thrombosis and a characteristic skin rash. Unusual cases of deficiency of glucagon secretion have been reported in babies. This results in severely low blood glucose which cannot be controlled without administering glucagon.

Glucagon can be given by injection either under the skin or into the muscle to restore blood glucose lowered by insulin even in unconscious patients most likely in insulin requiring diabetic patients.

It can increase glucose release from glycogen stores. Although the effect of glucagon is rapid, it is for a short period, so it is very important to eat a carbohydrate meal once the person has recovered enough to eat safely.

They were approved for therapy by the FDA and EMA in , although albiglutide was withdrawn from the market in for economic reasons.

A recent development has been the formulation of GLP-1 receptor agonists for oral administration. To date, the only oral GLP-1 receptor agonist available for clinical use is oral semaglutide.

The formulation of oral semaglutide was achieved by coupling semaglutide to sodium- N -[8- 2-hydroxybezoyl -amino]caprylate SNAC , which functions as an absorption enhancer. SNAC raises the local pH in the stomach, which leads to higher solubility of semaglutide and protection from degradation by gastric acid.

When the SNAC—semaglutide complex reaches the gastric epithelium, the lipophilic SNAC enters the cell membrane, which affects its fluidity, leading to rapid transcellular absorption of semaglutide [ 14 , 28 ]. However, absorption is still low and ingestion of a 14 mg tablet of semaglutide is required to achieve comparable plasma levels to those achieved with 1 mg of the s.

form [ 29 ]. Oral semaglutide is taken once daily and reduces HbA 1c levels to a significantly higher extent than DPP-4 inhibition or sodium—glucose cotransporter 2 SGLT-2 inhibition and to a similar extent as liraglutide, whereas body weight is reduced by a significantly higher extent than by DPP-4 inhibition and liraglutide and to a similar extent as SGLT-2 inhibition [ 30 , 31 ].

The clinically developed GLP-1 receptor agonists have all been shown to have glucose-lowering effects. Of most importance are the stimulation of beta cell function, reduction of glucagon secretion and delay in gastric emptying, which together lower fasting and postprandial glucose and HbA 1c levels; the induction of satiety with reduction in body weight; and the beneficial effects on cardiovascular risk, as evident from the cardiovascular outcomes trials Fig.

The longer acting GLP-1 receptor agonists are more effective than the shorter acting forms at reducing HbA 1c and fasting glucose levels, whereas the shorter acting forms are more effective at reducing postprandial glucose levels [ 3 ]. The latter differentiation depends on the sustained ability of short-acting GLP-1 receptor agonists to delay gastric emptying by inhibiting gastric motility, as tachyphylaxia of this effect appears after long-term GLP-1 receptor agonism [ 3 ].

Furthermore, the smaller longer acting forms are more effective than the larger longer acting forms at reducing body weight [ 3 ], which may be due to the smaller forms more readily passing the blood—brain barrier.

All GLP-1 receptor agonists are safe in terms of cardiovascular outcomes, and liraglutide, semaglutide, albiglutide, dulaglutide and efpeglenatide have been shown to have cardiovascular benefits in cardiovascular outcomes trials [ 22 ].

GLP-1 receptor agonists are associated with a minimal risk of hypoglycaemia because of the glucose dependency of the islet effects [ 32 ]. Furthermore, adverse events are rare, except for nausea and vomiting during the initial phase of therapy, and are similar between the GLP-1 receptor agonists [ 3 ].

It may therefore be concluded that, as glucose-lowering therapy, semaglutide both s. and oral forms and dulaglutide have an advantage over the other GLP-1 receptor agonists in terms of lowering glucose; semaglutide both s. and oral forms has an advantage in terms of reducing body weight; and liraglutide, s.

semaglutide and dulaglutide have beneficial effects on cardiovascular outcomes. This provides the background to the recent recommendations on the management of hyperglycaemia in type 2 diabetes by the EASD and ADA [ 33 ].

Besides the production of formulations of GLP-1 receptor agonists with longer durations of action, other strategies for harnessing the glucose-lowering actions of GLP-1 have been developed. The most successful of these, and to date the only one that has reached the clinic, is DPP-4 inhibition.

Shortly after the demonstration that the enzyme DPP-4 is responsible for the rapid inactivation of GLP-1, the idea of inhibiting DPP-4 to prolong the duration of action of GLP-1 and glucose-dependent insulinotropic polypeptide [GIP] was put forward reviewed in [ 34 ].

DPP-4 inhibition increases intact and active GLP-1 and GIP levels after a meal and the levels remain elevated until the next meal. This results in effects secondary to both GLP-1 and GIP receptor activation, such as increased beta cell function and inhibition of glucagon secretion [ 35 ].

The levels of GLP-1 achieved are lower than the corresponding levels seen after administration of GLP-1 receptor agonists. Therefore, although DPP-4 inhibition reduces both fasting and postprandial glucose and HbA 1c levels, the effects are weaker than for GLP-1 receptor agonists, and they do not exhibit a body weight reduction effect, although they are body weight neutral.

The first demonstration that DPP-4 inhibition reduces blood glucose levels in type 2 diabetes was published in [ 36 ]. The first DPP-4 inhibitor, sitagliptin, was approved by the FDA in and by the EMA in ; this was followed by approval of vildagliptin, alogliptin, saxagliptin and lingaliptin [ 37 ].

Several other small molecules that inhibit DPP-4 have since been developed, such as gemagliptin, anagliptin and teneligliptin. DPP-4 inhibitors reduce HbA 1c levels and have a low risk of hypoglycaemia or other adverse events [ 38 ], except for a potential risk of hospitalisation for heart failure in the case of saxagliptin [ 38 ].

They were also shown to be safe in large cardiovascular outcomes trials but were not found to have cardioprotective effects [ 39 ]. Today, their use has increased worldwide and they have a major role in primary care as glucose-lowering therapy among older people [ 40 ].

Recently, novel insights into the binding characteristics of the GLP-1 receptor have allowed the development of non-peptide GLP-1 receptor activators [ 41 , 42 ]. These small molecules bind to the receptor, stimulate insulin secretion and cAMP production in a glucose-dependent mechanism and also lower glucose in experimental models of diabetes in animals.

A Phase I trial of the small non-peptide GLP-1 receptor agonist danuglipron in 98 patients with type 2 diabetes found that it had a similar glucose-lowering ability as the clinically used GLP-1 receptor agonists and was well tolerated during the 4 week study period [ 43 ].

Stimulation of GLP-1 secretion from enteroendocrine L cells is another approach that may be able to realise the therapeutic potential of GLP-1, perhaps in combination with DPP-4 inhibition to prevent the inactivation of the GLP-1 released.

The regulation of GLP-1 secretion both in humans [ 44 ] and at the cellular level [ 45 ] has been studied but, except for the finding that ingestion of whey protein as a preload 30 min before a meal augments the GLP-1 response, with clinical benefits for type 2 diabetes [ 46 ], it has been difficult to translate the knowledge gained into clinically relevant formulations.

A trial of encapsulated glutamine, for example, failed to increase GLP-1 secretion in healthy participants or those with type 2 diabetes [ 47 ]. Newer approaches, such as activation of the Takeda G protein-coupled receptor 5 TGR5; bile acid receptor in L cells have shown more promise in experimental systems [ 48 ], but the results have not yet been translated to humans.

Glucagon is processed from its precursor, proglucagon, by prohormone convertase 2 and secreted from pancreatic alpha cells. The role of glucagon in maintaining glucose homeostasis by increasing hepatic gluconeogenesis and glycogenolysis in response to low glucose levels has been exhaustively studied.

The sustained action of glucagon causes hyperglycaemia, and glucose-mediated inhibition of glucagon secretion is impaired in patients with type 2 diabetes see comprehensive reviews in [ 49 , 50 ]. Glucagon exerts its actions via the glucagon receptor, a seven-transmembrane receptor coupled to Gα s and G q proteins.

The glucagon receptor is primarily expressed in the liver but also in the central nervous system, kidney, gastrointestinal tract and pancreas [ 49 , 50 ]. In addition to its hyperglycaemic action, glucagon has been reported to activate lipolysis and inhibit lipogenesis in the liver.

For instance, the administration of glucagon receptor antagonists increased hepatic fat content and plasma concentrations of LDL-cholesterol in people with type 2 diabetes [ 51 ]. Furthermore, leptin receptor-deficient mice, a mouse model of obesity and diabetes, and people with endogenous glucagon deficiency pancreatectomised individuals treated with glucagon antisense oligonucleotide have increased hepatic fat [ 52 , 53 ].

These data suggest that inhibition of glucagon receptor signalling results in hepatic lipid accumulation. Consistent with this, the acute administration of glucagon decreased NEFA and triacylglycerol plasma concentrations and reduced hepatic triglyceride content in wild-type mice [ 54 ].

Glucagon has also been shown to promote satiety and to increase energy expenditure in both rodents and humans. The satiety effect of glucagon was blocked after disconnection of the hepatic branch of the abdominal vagus nerve [ 55 ]. The ability of glucagon to increase energy expenditure was first demonstrated in rats in [ 57 ] and was subsequently confirmed in different species including humans [ 58 ], although one study reported that glucagon infusion over 72 h did not increase energy expenditure in healthy individuals with overweight or obesity [ 59 ].

In clinical studies, the stimulatory effect of glucagon on energy expenditure is heterogeneous depending on feeding status preprandial vs postprandial and the mechanism by which this occurs is not known. Rodents can increase their energy expenditure via activation of brown adipose tissue BAT.

However, glucagon can stimulate energy expenditure in species with little BAT adult dogs or no BAT pigs activity. Therefore, it is accepted that glucagon may affect energy expenditure via BAT-independent mechanisms for review see [ 60 , 61 ]. Circulating fibroblast growth factor 21 FGF21 is also implicated in glucagon-induced energy expenditure, as mice lacking FGF21 are protected from this effect [ 62 ].

Whether this mechanism occurs in other species remains to be investigated. Therefore, despite its hyperglycaemic action, glucagon triggers lipid catabolism and energy expenditure and reduces food intake Fig.

These features support the rationale for using glucagon in combination with other gut hormones as described below. GIP is a 42 amino acid protein Fig. GIP was originally reported to inhibit gastric acid secretion and was thus named gastric inhibitory polypeptide.

As GIP became established as an incretin hormone potentiating insulin release from beta cells in a glucose-dependent manner, it was renamed glucose-dependent insulinotropic polypeptide.

The insulinotropic effect of GIP and GLP-1 is additive in healthy humans but is impaired in people with type 2 diabetes [ 61 ]. GIP also exhibits protective effects on the survival of pancreatic beta cells [ 63 ].

Structures of a GLP-1, b GIP and c tirzepatide [ 19 , 88 , 90 ]. Amino acids are illustrated in circles; blue circles show amino acids that are identical to those in GLP-1; black circles show amino acids that are present in GIP and tirzepatide but not in GLP-1; red circles show amino acids that are identical in tirzepatide and exenatide see Fig.

AiB, aminoisobutyric acid. GIP has also been shown to have actions beyond its effect on insulin secretion Fig. It has been reported to modulate fatty acid metabolism but its role in this respect remains unclear. Some studies have shown that it stimulates lipogenesis and lipid uptake in adipose tissue and reduces lipolysis [ 64 ].

Consistent with this, whole-body GIP receptor deficiency and GIP deficiency protect against obesity induced by long-term high fat feeding in mice [ 65 , 66 ]. However, other studies have reported that GIP may have lipolytic activity [ 67 ] and that GIP-overexpressing transgenic mice exhibit resistance to high fat diet feeding [ 68 ].

Furthermore, the activation of the GIP receptor also improved glucose metabolism in diet-induced obese mice without changing body weight or fat mass [ 69 ].

In line with this, activation of the GIP receptor in the hypothalamus the brain GIP receptor is located in the hypothalamus and hindbrain decreased food intake in diet-induced obese mice [ 70 , 71 ].

These preclinical results were supported by genome-wide association studies, which have identified variants with reduced activity at the human GIP receptor locus that are associated with reduced BMI [ 72 ].

More recent studies have shown that GIP analogues lead to weight loss, especially in combination with GLP-1 receptor agonists reviewed in [ 71 ]. One such study showed that chronic daily administration of GIP analogues decreased food intake and resulted in body weight reduction in diet-induced obese mice without alterations in energy expenditure [ 73 ].

A recent elegant study also found that brain- Gipr knockout mice and humanised h GIPR knock-in mice with brain- hGIPR deletion showed decreased body weight and improved glucose metabolism [ 70 ].

In addition, acute central and peripheral administration of acyl-GIP increased c-Fos neuronal activity in hypothalamic feeding centres and decreased body weight and food intake [ 70 ].

Thus, it appears that brain GIP receptor signalling plays a key role in the regulation of energy balance. These findings also indicate that, at least at the central level, agonism of the GIP receptor exerts a catabolic action, suggesting that the reduction in body weight found in other studies after the administration of GIP receptor antagonists was not mediated by the brain.

Additional studies have demonstrated that combining GIP and GLP-1 receptor agonists is more effective at reducing body weight than using either individually.

For instance, the co-administration of acyl-GIP and acyl-GLP-1 decreased body weight, food intake and fat mass to a greater degree than administration of either of the agonists alone [ 74 ].

The use of glucagon in patients with type 2 diabetes might seem illogical because of its action of promoting hyperglycaemia. However, as described earlier, its favourable effects on lipolysis and energy expenditure while reducing food intake make it an attractive option, especially if combined with the insulinotropic action of GLP Moreover, previous studies have indicated that oxyntomodulin, which binds to both the glucagon receptor and the GLP-1 receptor, increases energy expenditure and decreases energy intake [ 75 ].

Weekly administration of this molecule normalised glucose tolerance and adiposity in diet-induced obese mice. Body weight reduction was achieved by the reduction of food intake and increased energy expenditure [ 76 ]. SAR and MEDI also named cotadutide have undergone Phase II clinical trials [ 78 , 79 ].

For instance, in a randomised, placebo-controlled, double-blind Phase I study of ascending single doses of cotadutide in healthy individuals with overweight, there were dose-dependent improvements in glucose excursions post meal within 24 h and food intake reduction after a single dose of μg [ 82 ].

In addition, cotadutide was shown to be safe and, in common with the GLP-1 analogues, was associated with dose-dependent gastrointestinal adverse events, especially nausea and vomiting [ 82 ].

In a combined multiple ascending dose and Phase IIa study in people with type 2 diabetes over 41 days, daily doses of cotadutide up to μg improved fasting and postprandial glucose levels and reduced body weight compared with placebo [ 79 ]. In a separate follow-up Phase IIa study over 49 days, the mechanism of improved glucose metabolism was shown to be a combination of enhanced insulin secretion and delayed gastric emptying [ 83 ].

While SAR has been discontinued, cotadutide is being evaluated in participants with non-cirrhotic non-alcoholic steatohepatitis with fibrosis because of its beneficial effects in animal studies [ 84 ]. Its glucose-lowering and insulinotropic efficacy was superior to that of selective GLP-1 receptor agonists in diet-induced obese and leptin receptor-deficient mice, as well as in monkeys and humans [ 74 ].

Tirzepatide binds with a higher affinity to the GIP receptor than the GLP-1 receptor. In receptor binding studies, the affinity of tirzepatide was comparable to that of native GIP for the GIP receptor and approximately fivefold weaker than that of native GLP-1 for the GLP-1 receptor [ 88 ].

In HEK cells expressing human GIP receptor or GLP-1 receptor, tirzepatide potently stimulated cAMP accumulation by both receptors, and the potency of tirzepatide was similar to that of native GIP and approximately fold weaker than that of GLP-1 in these assays [ 88 ].

However, despite affinity, albeit lower, of tirzepatide for the GLP-1 receptor, tirzepatide had no effect on body weight, food intake, fasting insulin, endogenous glucose production and insulin-stimulated glucose uptake in skeletal muscle and subcutaneous white adipose tissue of GLP-1 receptor knockout mice [ 89 ].

Tirzepatide was approved by the FDA and EMA for the treatment of type 2 diabetes in Tirzepatide treatment was administered at three final doses 5, 10, 15 mg per week , with treatment initiated at 2.

These trials showed that tirzepatide reduced fasting plasma glucose and HbA 1c levels not only compared with placebo but also compared with the insulins degludec and glargine or semaglutide [ 90 , 91 , 92 ].

Interestingly, tirzepatide also markedly reduced body weight in patients with type 2 diabetes, which led to studies on its efficacy for the treatment of obesity in the absence of type 2 diabetes. Remarkably, tirzepatide 15 mg per week reduced body weight by up to The most common adverse events were nausea, vomiting, diarrhoea and constipation.

These gastrointestinal side effects appear to be qualitatively similar to those reported in clinical studies of selective GLP-1 receptor agonists. There is also an ongoing cardiovascular outcomes trial of tirzepatide SURPASS-CVOT in individuals with type 2 diabetes and cardiovascular disease [ 91 ], which, if successful, will broaden the use of tirzepatide to those with manifest or increased risk for CVD, as is the case for GLP-1 receptor agonists [ 22 ].

The success of dual receptor agonists for the treatment of type 2 diabetes and obesity in clinical trials, including the approval of one such drug by the FDA and EMA currently only for type 2 diabetes , has prompted the search for new combinatorial approaches.

The synergistic metabolic benefits of simultaneous modulation of glucagon, GLP-1 and GIP receptors through a single molecule were first discovered and validated in [ 94 ]. Another triple receptor agonist named SAR was later designed and tested in diet-induced obese mice, confirming the initial discoveries reported in [ 95 ].

The safety, tolerability, pharmacokinetics and pharmacodynamics following single ascending s. doses of SAR were studied in lean to overweight individuals and, at the two highest doses tested 80 and ug , fasting blood glucose levels reached a nadir within the first hour [ 95 ].

Single doses of SAR up to μg were well tolerated and the most frequent treatment-emergent adverse events were gastrointestinal disorders, as is typical with these compounds.

New triple receptor agonists have recently been designed and have shown a prolonged duration of action, supporting the possibility of once-weekly administration in humans.

In a Phase I single ascending dose study in healthy participants, LY showed a similar safety and tolerability profile to that of other incretins and a reduction in body weight up to day 43 after a single dose [ 97 ].

This compound was further tested in people with type 2 diabetes and, at week 12, plasma glucose and HbA 1c levels decreased significantly from baseline at the highest doses [ 98 ]. Other gut hormone-based combination pharmacotherapies have been designed and have shown beneficial effects in preclinical models.

The strategy employed has been to link GLP-1 or glucagon receptor agonists to nuclear hormones such as oestrogens, thyroid hormones and dexamethasone reviewed in [ 64 , 96 , 99 ].

In the case of thyroid hormones, T 3 was conjugated with glucagon to deliver T 3 specifically to the liver; this resulted in a reduction in body weight and corrected dyslipidaemia in several mouse models of obesity [ ]. Finally, dexamethasone was conjugated with GLP-1 and this peptide induced weight loss in obese mice with a greater efficiency than GLP-1 alone [ ].

Thus, the use of combination pharmacotherapy involving other molecules in addition to gut hormones seems to be a plausible approach to treating the metabolic syndrome. It should be noted that these unimolecular compounds have been tested only in preclinical models and have not been compared with other dual receptor agonists such as tirzepatide; further studies should elucidate whether their action is superior to that of the clinically tested drugs.

It is 30 years since the first demonstration of the glucose-lowering effects of the gut hormone GLP-1 in people with diabetes [ 9 ].

This development has led to the introduction of several GLP-1 receptor agonists and DPP-4 inhibitors on the market [ 3 ], which are featured prominently in current recommendations because of their effectiveness, safety and proven cardiovascular benefits [ 33 ].

GLP-1 receptor agonists have also shown success in other therapeutic areas apart from type 2 diabetes and obesity, in particular for non-alcoholic fatty liver disease [ ].

At the same time, we are facing an exciting multifaceted future, with several novel developments on the horizon with the potential to change the clinic setting, including the development of oral GLP-1 receptor agonists and the emerging formulations of GIP receptor agonists and dual and triple receptor agonists, which have shown clear therapeutic potential.

The dual and triple receptor agonist formulations are also expected to undergo cardiovascular outcomes trials. Other developments include the ending of patents for DPP-4 inhibitors, which began in for sitagliptin and which will follow for other DPP-4 inhibitors in the coming years.

This will result in lower prices, which may result in increased interest in and use of these drugs. The landscape for guidelines and recommendations is also changing, with a higher emphasis on efficacy than before.

Hence, in , glucose-lowering efficacy and proven cardiovascular effects were important for the strong positioning of semaglutide, dulaglutide and tirzepatide in guidelines on the management of hyperglycaemia in type 2 diabetes [ 33 ], and a similar strong positioning of incretin therapy was seen in guidelines on primary care [ 39 ].

We can also expect more guidelines on weight management and management of kidney disease using incretin therapy, and clinical studies may show beneficial effects of the early introduction of combination therapy on the long-term control of blood glucose levels.

In the future, the successful development of small molecule GLP-1 receptor agonists and therapy based on glucagon and other gut hormones may provide a broader arsenal for the treatment of both hyperglycaemia and overweight. At the same time, increased knowledge of differences in drug response depending on phenotype or genetics may pave the way to more individualised therapy; studies on personalisation are now beginning to emerge, with a recent finding that genetic variations in the GLP-1 receptor, and also in arrestin B1, are important for the glycaemic effects of GLP-1 receptor agonists [ ].

The future therefore holds promise for gut hormone-based therapy in the context of both the development of novel drugs and their inclusion in recommendations and guidelines. Moore B, Edie ES, Abram JS On the treatment of diabetes mellitus by acid extract of duodenal mucous membrane.
