Mucopolysaccharide Matrix in Sputum (N/A)
- Target
- N/A
- Molecular classification
- Extracellular matrix, Polysaccharide, Glycoprotein complex, Glycosaminoglycan (GAG) network
01
Overview
The mucopolysaccharide matrix in sputum is a complex hydrogel composed primarily of mucins (MUC5AC, MUC5B) and glycosaminoglycans (GAGs), forming the structural backbone of airway secretions. This matrix provides a protective barrier, traps inhaled particles, and is crucial for mucociliary clearance. In diseases like cystic fibrosis and COPD, alterations in matrix composition and increased viscosity contribute to impaired airway function and disease progression. While not a direct drug target, its components and properties are indirectly modulated by therapies aiming to improve mucus clearance.
