Investigating how cannabinoid receptors affect fat and sugar regulation using human fat samples

Translational Study Using Human Abdominal Adipose Tissue Biopsies to Investigate the Role of Cannabinoid Receptor 1 (CB1) in Controlling Endocannabinoid and Adipokine Secretion

Not applicable Interventional Centre Hospitalier Universitaire Dijon · NCT04940962

This study is testing how cannabinoid receptors in fat cells affect sugar and fat levels in people with abdominal obesity and type 2 diabetes, using samples from their fat tissue.

What this trial studies

This study examines the role of cannabinoid receptor 1 (CB1) in regulating endocannabinoid and adipokine secretion in individuals with abdominal obesity and type 2 diabetes. By sampling human abdominal adipose tissue, the research aims to understand how the endocannabinoid system influences metabolic processes related to obesity and diabetes. The study focuses on both diabetic and non-diabetic obese subjects, as well as healthy controls, to explore the differences in endocannabinoid levels and their effects on metabolism. Participants will undergo visceral surgery to provide adipose tissue samples for analysis.

Who should consider this trial

Good fit: Ideal candidates include men or post-menopausal women aged 18 to 80 with a BMI over 30, either diabetic or non-diabetic, who are scheduled for visceral surgery.

Not a fit: Patients with a BMI under 30, those with chronic inflammatory diseases, or those currently undergoing cancer treatment may not benefit from this study.

Why it matters

Potential benefit: If successful, this research could lead to new therapeutic strategies for managing type 2 diabetes and obesity.

How similar studies have performed: While the specific approach of using human adipose tissue biopsies to study CB1's role is novel, related studies have indicated the endocannabinoid system's involvement in obesity and diabetes management.
