Bronchogen
Also known as: Ala-Glu-Asp-Leu · Bronchial peptide bioregulator
A tetrapeptide (Ala-Glu-Asp-Leu) from the Khavinson bioregulator series specifically targeting bronchial and lung tissue. Studied for COPD, chronic bronchitis, and smoking-related lung damage. Normalizes bronchial epithelium proliferation and reduces respiratory inflammation.
What is Bronchogen? A tetrapeptide (Ala-Glu-Asp-Leu) from the Khavinson bioregulator series specifically targeting bronchial and lung tissue. Studied for COPD, chronic bronchitis, and smoking-related lung damage. Normalizes bronchial epithelium proliferation and reduces respiratory inflammation.
How does Bronchogen work? Bronchogen penetrates bronchial epithelial cell nuclei and regulates gene expression in respiratory tissue. It inhibits excessive cell proliferation and inflammation while promoting repair of damaged bronchial mucosa. Anti-inflammatory effects mediated through NF-kB pathway suppression and reduced TNF-alpha and IL-6 production in lung tissue.
Benefits of Bronchogen: Normalizes bronchial epithelium function; Anti-inflammatory in respiratory tissue; COPD and chronic bronchitis research; Promotes repair of smoking-damaged lung tissue; Reduces bronchial mucus hypersecretion; Anti-aging effects in lung tissue; May improve respiratory function in elderly patients
Bronchogen dosage: Standard Khavinson protocol: 1-2mg/day SubQ or IM for 10 days, 2x per year.
