MECHANISMS OF GOBLET CELL HYPERPLASIA INDUCED BY SIMULATED VIRAL EXPOSURE OR TH2 CYTOKINES.

Introduction:  Goblet cell hyperplasia is a common feature of respiratory epithelial response to numerous environmental challenges (e.g. cigarette smoke, air pollution, viral infection) and is also commonly observed in respiratory […]

HISTAMINE MAY INDUCE AIRWAY REMODELING THROUGH RELEASE OF EPIDERMAL GROWTH FACTOR RECEPTOR LIGANDS FROM BRONCHIAL EPITHELIAL CELLS

Asthma is a chronic inflammatory disease that is associated with airway remodeling, including hyperplasia of airway epithelial cells and airway smooth muscle cells, and goblet cell differentiation. We wished to […]
