Overview

Bronchogen is a synthetic tripeptide consisting of Alanine-Glutamic acid-Aspartic acid (AED), developed as a lung-specific bioregulator by Professor Vladimir Khavinson at the St. Petersburg Institute of Bioregulation and Gerontology. It was designed to target bronchial epithelial cells and lung parenchyma, modulating gene expression related to respiratory function, mucosal immunity, and tissue repair. In the Khavinson bioregulation framework, Bronchogen restores age-related and disease-related decline in respiratory tissue gene expression, supporting bronchial epithelial integrity, mucociliary clearance, and local immune defense. It has been studied in models of chronic obstructive pulmonary disease (COPD), bronchitis, and age-related respiratory decline. Available in Russia as an oral supplement, Bronchogen is typically used in 10-30 day courses and is often combined with other tissue-specific bioregulators. Research data is primarily from Russian institutions.

Mechanism of Action

Bronchogen is proposed to interact with DNA sequences in bronchial epithelial cells, modulating gene expression related to mucin production, surfactant synthesis, ciliary function, and local immune defense (secretory IgA, antimicrobial peptides). The tripeptide's small size allows cell membrane penetration without receptor-mediated mechanisms. Research suggests Bronchogen normalizes the expression of genes involved in bronchial epithelial differentiation, reduces chronic inflammatory gene expression (TNF-α, IL-6 in airway tissue), and supports mucosal barrier function. In COPD models, it has been reported to reduce airway remodeling and restore ciliary beat frequency. The peptide may also modulate local oxidant-antioxidant balance in lung tissue, reducing oxidative damage from chronic inflammation or environmental exposures.
