Oxidative stress and innate immunity responses in cigarette smoke stimulated nasal epithelial cells

2013

Cigarette smoke extracts (CSE) may play a significant role in diseases of the upper airway including chronic rhinosinusitis. Even short term exposure of cigarette smoke has adverse effects on mitochondrial functions and redox homeostasis in tissues which may progress to further complications associated with chronic smoking. Cigarette smoke alters toll-like receptor 4 (TLR4) expression and activation in bronchial epithelial cells. Carbocysteine is an anti-oxidant and mucolytic agent. The effects of carbocysteine on CSE induced oxidative stress and on associated innate immune and inflammatory responses in nasal epithelial cells are largely unknown. The present study was aimed to assess in CSE…
