Research Abstract

We demonstrated that mechanical stretch activates Ca^<2+> influx via stretch-activated channels and induces production of cytokine/chemokines (IL-6, IL-8, and MCP-1) in human airway smooth muscle cells and pulmonary microvascular endothelial cells. Thus, excessive mechanical strain would contribute to the pathogenesis of lung and airway remodeling via altering cellular properties of pulmonary cells.
