Phlegm resolution via modulation of mucus secretion and clearance in airways

The submitted entity refers to the resolution of airway phlegm (excess mucus), which is achieved through modulation of mucus secretion by epithelial and submucosal gland cells and enhancement of its clearance, primarily through the mucociliary escalator and cough. This process is central to airway defense and the prevention of lung disease. Therapeutic modulation typically targets either reduction in mucus production/secretion (e.g., targeting MUC5AC/MUC5B expression or secretion), improvement of mucus properties (hydration, viscosity, breakdown), or enhancement of clearance mechanisms (ciliary function, hydration). There is no single druggable target called "phlegm resolution"—instead, several proteins (e.g., ion channels like CFTR, ENaC; mucins such as MUC5AC, MUC5B; purinergic receptors) and cell types (goblet and club cells) mediate the underlying processes.
