Semaglutide, a powerful derivative of the natural peptide GLP-1, offers more than just blood sugar control. Its unique properties have been studied for their potential benefits on lung, heart, and liver function, as well as their potential in slowing or preventing the effects of Alzheimer’s disease.

One of the remarkable features of Semaglutide is its ability to reduce appetite. By delaying gastric emptying and decreasing intestinal motility, it can help curb cravings and promote weight loss. Additionally, this GLP-1 analogue has shown effectiveness in stimulating insulin secretion and suppressing glucagon secretion.

Semaglutide and GLP-1 Overview

GLP-1, short for glucagon-like peptide-1, is a hormone the intestines produce when food is consumed. It is crucial in regulating insulin secretion, appetite, and glucose metabolism. GLP-1 stimulates the release of insulin from pancreatic beta cells, suppresses glucagon secretion, and slows down gastric emptying.

These actions contribute to improved glycemic control and satiety. In addition to its physiological functions, GLP-1-based medications, such as semaglutide, have been developed to treat type 2 diabetes. These medications aim to enhance the effects of GLP-1, helping to manage blood sugar levels and support overall metabolic health. GLP-1 has also demonstrated cardioprotective effects and may reduce the risk of cardiovascular complications in individuals with diabetes.

Semaglutide and GLP-1 Research

The Incretin Effect of GLP-1

GLP-1 is an incretin hormone produced in the gut that transmits signals to pancreatic β cells.
Research suggests that GLP-1, along with another incretin hormone called GIP (glucose-dependent insulinotropic polypeptide), has a significant role in transmitting signals from the gut to the pancreatic β cells. Both GLP-1 and GIP have insulinotropic effects, meaning they stimulate insulin secretion from the pancreas.

Semaglutide GLP-1 and Beta Cell Protection

GLP-1 is crucial in protecting pancreatic beta cells. Beta cells are responsible for producing and releasing insulin, which helps regulate blood sugar levels. GLP-1 exerts several protective effects on these beta cells:

  • Enhanced insulin secretion: GLP-1 stimulates the secretion of insulin from beta cells, helping to maintain optimal blood sugar control.
  • Beta cell survival: GLP-1 helps protect beta cells from apoptotic cell death, promoting their survival and preserving their function over time.
  • Improved glucose sensitivity: GLP-1 enhances the ability of beta cells to respond to glucose levels in the blood, ensuring that insulin is released appropriately.
  • Preservation of beta cell mass: GLP-1 promotes beta cell proliferation, leading to an increase in the overall mass of beta cells in the pancreas. This helps compensate for any loss of beta cells and maintain insulin production.

Semaglutide GLP-1 and Appetite

GLP-1 and appetite are connected through several mechanisms. GLP-1 plays a role in appetite regulation and weight maintenance by having actions on the gastrointestinal tract and directly regulating appetite. When GLP-1 is released, it can create a feeling of fullness or satiety, reducing hunger and food intake.

This effect on appetite is believed to be mediated through interactions with brain areas involved in appetite regulation and reward. GLP-1 receptor agonists, which stimulates GLP-1 receptors, have been shown to promote satiety, reduce food intake, and potentially contribute to weight loss efforts. Overall, GLP-1 and appetite are linked in a way that GLP-1 can help control appetite and influence food intake, making it relevant in understanding hunger regulation and potential strategies for managing weight.

It is important to note that this research is conducted on mice, allowing us to get a greater insight before human trials begin.

Semaglutide Potential Cardiovascular Benefits of GLP-1

GLP-1 has been the subject of research regarding its potential cardiovascular benefits. Several mechanisms have been identified that suggest GLP-1 may positively affect cardiovascular health.

One mechanism is the direct action of GLP-1 on the heart and blood vessels. GLP-1 receptors are present in the cardiovascular system, and activating these receptors can lead to vasodilation (widening of blood vessels), reduced blood pressure, and improved cardiac function.

Another important mechanism is the indirect effect of GLP-1 on metabolic factors. GLP-1 can enhance insulin secretion and improve insulin sensitivity, which helps to regulate blood sugar levels. By promoting better glucose control, GLP-1 may reduce the risk of developing conditions like diabetes associated with an increased risk of cardiovascular disease.

In addition, GLP-1 may have anti-inflammatory and anti-atherosclerotic effects. Chronic low-grade inflammation and the development of atherosclerosis are key contributors to cardiovascular disease. Studies have suggested that GLP-1 may reduce inflammation and inhibit the formation of plaques in blood vessels, potentially minimizing the risk of cardiovascular events. These potential cardiovascular benefits have been researched on dogs.

GLP-1 and the Brain

GLP-1, specifically the semaglutide variant, has shown promising evidence for its potential to improve learning and protect neurons against Alzheimer’s. Multiple studies conducted on mice have demonstrated positive effects of GLP-1 on associative and spatial learning, even in mice with specific gene defects. Rats overexpressing the GLP-1 receptor in certain brain regions displayed significantly improved learning and memory compared to normal controls.

Additionally, research on mouse models suggests that GLP-1 can protect against excitotoxic neuron damage, providing complete protection against glutamate-induced apoptosis in rat models of neurodegeneration. GLP-1 has also been found to stimulate neurite outgrowth in cultured cells. These findings have given researchers hope that further investigation into the semaglutide variant of GLP-1 could reveal its potential to halt or even reverse certain neurodegenerative diseases.

Another intriguing discovery from mouse models is that GLP-1, along with its analogue exendin-4, has been found to reduce levels of amyloid-beta in the brain. Amyloid-beta is a key component of Alzheimer’s disease plaques and is associated with disease severity. While the impact of GLP-1 on amyloid-beta accumulation is still unknown, these findings provide promising insights into potential interventions for the transition from mild cognitive impairment to full-blown Alzheimer’s disease.

It’s important to note that GLP-1 shows some side effects and exhibits good subcutaneous bioavailability in mice. However, we should emphasize that the dosage administered to mice does not directly translate to humans. GLP-1 should only be acquired by licensed researchers exclusively for educational and scientific research, as it is not intended for human consumption.

In 1986 Professor Jens Juul Holst discovered the GLP-1 hormone in connection with his work on stomach ulcer surgery. Since the discovery, Novo Nordisk have used the research to successfully develop products to treat diabetes and obesity. The hormone GLP-1 can be used to regulate blood sugar levels and satiety. Not only has it made treatment of obesity and diabetes possible, it has also proven useful preventatively through early diagnosis for citizens who are at risk of developing diabetes and obesity. In 2015, Jens Juul Holst received the prestigious international Fernström prize for his research on GLP-1. He is one of the most cited researchers in Europe, with over 1,200 published articles and citations in over 3,500 articles annually.
