Summary
Spexin, an adipokine, plays a key role in regulating metabolism and may offer new therapeutic targets for obesity and type 2 diabetes (T2DM). Understanding spexin
Area of Science:
- Metabolic research
- Endocrinology
- Obesity and diabetes research
Background:
- Insulin resistance, often caused by obesity, is a primary driver of type 2 diabetes (T2DM).
- Dysregulated adipokine secretion from visceral fat is a hallmark of obesity and T2DM.
- Spexin, an adipokine negatively correlated with energy storage, influences metabolic processes via GALR2/3 receptors.
Purpose of the Study:
- To review recent advancements and mechanisms of spexin in obesity and T2DM.
- To analyze spexin's role in the hypothalamic melanocortin system.
- To explore spexin's potential in enhancing insulin sensitivity and glucose tolerance.
Main Methods:
- Literature review of basic research and clinical findings on spexin.
- Analysis of spexin's interaction with the hypothalamic melanocortin system.
- Examination of spexin's influence on energy expenditure and intake.
Main Results:
- Spexin influences inflammation, browning, lipolysis, energy expenditure, and eating behavior.
- Spexin impacts hypothalamic regulation of energy balance.
- Spexin may reduce energy intake and increase energy expenditure.
Conclusions:
- Spexin enhances insulin sensitivity and glucose tolerance.
- Further insight into spexin's mechanisms can lead to novel treatments for obesity and T2DM.
- Targeting the spexin system offers a promising therapeutic strategy for metabolic disorders.

01:30Regulation of Food Intake
204
Short-term regulation of food intake primarily involves neural signals from the gastrointestinal (GI) tract, blood nutrient levels, and GI tract hormones. Communication between the gut and brain via vagal nerve fibers plays a significant role in evaluating the contents of the gut. Clinical studies have shown that protein ingestion produces a more prolonged response in these nerve fibers compared to an equivalent amount of glucose. Additionally, the activation of stretch receptors caused by GI...

01:19Interactions Between Signaling Pathways
6.2K
Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...

01:37Hypothalamic-Pituitary Axis
59.7K
The response to stress—be it physical or psychological, acute or chronic—involves activation of the Hypothalamic-Pituitary-Adrenal (HPA) axis. The HPA axis is part of the neuroendocrine system because it involves both neuronal and hormonal communication. Its function is to regulate homeostatic systems—metabolic, cardiovascular, and immune—providing the necessary means to respond to a stressor.

01:28Sympathetic Pathways: Collateral Ganglia and Adrenal Medulla
1.2K
The sympathetic pathways of the collateral ganglia and adrenal medulla serve unique but interconnected roles in the sympathetic response.
Collateral Ganglia
Sympathetic preganglionic axons reach the collateral ganglia along the route of splanchnic nerves. These nerves bypass the sympathetic trunk and communicate with sympathetic postganglionic neurons housed in the prevertebral ganglia. These ganglia supply the organs of the abdominopelvic cavity.
The greater splanchnic nerve, formed by the...

01:24Glucagon-like Receptor Agonists
306
Incretins include glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP), which stimulate insulin secretion post-meals. In type 2 diabetes, GIP's efficacy is reduced, making GLP-1 a viable drug target. GIP originates from preproGIP.
GLP-1, when administered in high doses intravenously, triggers insulin secretion, inhibits glucagon release, slows gastric emptying, reduces food intake, and restores normal insulin secretion. However, its rapid inactivation by...

01:22Target Cell Response to Hormones
3.0K
Hormones intricately bind to receptors on the surface or within target cells, initiating a cascade of cellular responses.
Notably, the cellular response can be regulated by altering the number of receptors expressed in the cell. For example, prolonged exposure to elevated hormone levels results in a gradual decline or down-regulation in the number of receptors for that specific hormone on the cell surface. Conversely, in response to low hormone levels, cells may use up-regulation, producing an...
