Muc5b siRNA

Muc5b siRNA is a small interfering RNA (siRNA) therapeutic candidate designed to silence the expression of the MUC5B gene, which encodes Mucin 5B, a key gel-forming mucin in the respiratory tract. In conditions such as Alpha-1-antitrypsin deficiency (AATD), the overproduction of Muc5b—driven by neutrophil elastase activity and environmental factors like cigarette smoke—leads to impaired mucociliary transport and small airway obstruction. By utilizing the RNA interference (RNAi) pathway to degrade MUC5B mRNA, this siRNA reduces the synthesis of Mucin 5B protein, thereby restoring mucociliary clearance and potentially mitigating airway disease. Research presented by the University of Alabama at Birmingham highlights its potential as a targeted therapy for AATD-associated lung dysfunction.
