Mucous cell and serous cell of airway epithelium

Mucous cells (including goblet cells in the surface epithelium and mucous cells in submucosal glands) secrete high molecular weight mucins forming the mucus layer that traps particulates and pathogens. Serous cells, prevalent in submucosal glands, secrete watery fluids rich in proteins such as lysozyme, lactoferrin, and antimicrobial peptides, contributing to innate defense and maintaining mucus properties. Together, these cells are critical for mucociliary clearance and host defense in the airway. Altered function or number of these cells is central to the pathogenesis of airway diseases such as asthma, COPD, and chronic bronchitis. Key point: "Mucous and serous cells in airway epithelium" does not refer to a singular molecule or druggable target but to two epithelial cell types with important defensive and secretory roles. If you are seeking drug targets, focus would shift to specific molecular components such as mucin genes (e.g., MUC5AC) or regulatory receptors on these cells.
