Scientists restore lost protein to reverse lung disease in preclinical models

Researchers at the Fralin Biomedical Research Institute have identified a natural protective protein crucial for maintaining healthy lung blood vessels. In preclinical studies of pulmonary arterial hypertension, increasing this protein's expression reversed key disease features, including pulmonary vascular remodeling and heart dysfunction. This breakthrough suggests a new therapeutic approach to treating a serious condition that affects blood flow through the lungs. The findings could lead to innovative treatments that restore the body's natural protective mechanisms rather than just managing symptoms.
