Insights

Sodium-glucose co-transporter-2 inhibitors (SGLT2is) protect pancreatic beta-cells from failure in diabetes. These drugs improve beta-cell function and preserve mass by reducing glucose overload, aiding diabetes management.

Area of Science:

  • Endocrinology
  • Pharmacology
  • Diabetology

Background:

  • Diabetes pathophysiology involves chronic hyperglycemia, stressing pancreatic beta-cells and leading to reduced mass and function.
  • Sodium-glucose co-transporter-2 inhibitors (SGLT2is) offer antihyperglycemic effects with low hypoglycemia risk and organ protection.
  • SGLT2is may preserve beta-cell function by mitigating hyperglycemia-induced glucose overload.

Purpose of the Study:

  • To review preclinical and clinical data on SGLT2 inhibitors' effects on pancreatic beta-cell mass and function.
  • To discuss the mechanisms underlying the protective effects of SGLT2 inhibitors in beta-cells.

Main Methods:

  • Review of preclinical studies in animal models of diabetes.
  • Analysis of data from clinical trials in individuals with type 2 diabetes.

Main Results:

  • SGLT2 inhibitors have demonstrated increased beta-cell proliferation and/or reduced apoptosis in preclinical models.
  • Clinical trials indicate that SGLT2 inhibitors improve beta-cell function in patients with type 2 diabetes.
  • These effects suggest SGLT2is preserve beta-cell mass and function.

Conclusions:

  • SGLT2 inhibitors play a crucial role in preserving pancreatic beta-cell mass and function.
  • The glucose-lowering mechanism of SGLT2 inhibitors indirectly protects beta-cells from detrimental hyperglycemia.
  • SGLT2 inhibitors represent a promising therapeutic strategy for managing diabetes by safeguarding beta-cell health.

Oral Hypoglycemic Agents: Biguanides and Glitazones

Biguanides, particularly metformin (Glucophage), are insulin sensitizers that enhance glucose uptake, thereby reducing insulin resistance. Unlike sulfonylureas, metformin doesn't prompt insulin secretion, which helps to curb hypoglycemia risk. Metformin is beneficial in treating conditions like polycystic ovary syndrome due to its insulin-resistance reduction capability. The drug's primary action involves curtailing hepatic gluconeogenesis, a significant contributor to high blood...

Diabetes Mellitus: Type 2 and Gestational01:22

Diabetes Mellitus: Type 2 and Gestational

Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

Hormones Regulating Blood Glucose01:16

Hormones Regulating Blood Glucose

Insulin is released by beta cells of the pancreas when blood glucose levels are high. It facilitates glucose absorption and utilization in insulin-dependent cells with insulin receptors on their plasma membranes. Insulin promotes glucose uptake by increasing the number of glucose transport proteins in the cell membrane, allowing glucose to enter the cell. As a result, glucose utilization and ATP production are enhanced.
In addition to accelerating glucose uptake and utilization, insulin has...

Glucose Homeostasis: Pancreatic Islets and Insulin Secretion01:27

Glucose Homeostasis: Pancreatic Islets and Insulin Secretion

The pancreatic islets comprising only 1%-2% of the volume are highly vascularized and innervated mini-organs. They contain five endocrine cell types, including β cells that secrete insulin, which is synthesized as a single polypeptide chain, preproinsulin, processed to proinsulin, and finally to insulin and C-peptide. This process is complex and regulated, involving the Golgi complex, the endoplasmic reticulum, and the secretory granules of the β cell.
Insulin and C-peptide are...

Dipeptidyl Peptidase 4 Inhibitors01:23

Dipeptidyl Peptidase 4 Inhibitors

Dipeptidyl peptidase 4 (DPP-4) is a serine protease widely distributed in the body. It's involved in the inactivation of GLP-1 and GIP hormones, which are crucial for insulin regulation. DPP-4 inhibitors, such as sitagliptin (Januvia), saxagliptin (Onglyza), linagliptin (Tradjenta), alogliptin (Nesina), and vildagliptin (Galvus), help increase the proportion of active GLP-1, enhancing insulin secretion. These inhibitors work by competitively binding to DPP-4. This binding causes a...

Carbohydrate Metabolism01:36

Carbohydrate Metabolism

Carbohydrates are polymers composed of molecules containing atoms of carbon, hydrogen and oxygen. One gram of carbohydrate can provide four kilo-calories of energy, which makes it the most efficient instant energy source.
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...
