Concurrently, an elevation in the levels of key lipolytic receptors, specifically beta-3-adrenergic receptors within adipocytes, was observed in these models
Primarily, carnitine deficiency occurs because of a genetic defect preventing carnitine transport and a deficiency may result in confusion, heart pain, muscular weakness as well as obesity
These functions collectively sustain critical physiological processes: collagen biosynthesis (triple-helix stabilization), iron absorption (ferric iron reduction in enterocytes), and immune cell activation (neutrophil chemotaxis enhancement)
But this study challenges that narrative, showing that a hormone we thought of only as a metabolic regulator may interfere with muscle repair and growth. The findings also raise new questions about the long-term use of GLP-1based drugs, such as those prescribed for type 2 diabetes and obesity
