Modulation of Human Airway Smooth Muscle Migration by Lipid Mediators and Th-2 Cytokines

Cysteinyl leukotrienes and the T helper (Th)-2 cytokines IL-5 and IL-13 directly modulate human airway smooth muscle functions such as contraction and proliferation. We studied the effects of other lipid mediators involved in asthma pathophysiology such as prostaglandin D(2) (PGD(2)), lipoxin, and isoprostanes, and the cytokines, IL-5, IL-4, and IL-13 on human airway smooth muscle cell migration. Chemotaxis and chemokinesis of cultured airway …
