Effects of cigarette smoke and alcohol on ciliated tracheal epithelium and inflammatory cell recruitment.
Ciliated epithelium represents the first line of host defense against lung infection. Most alcoholics smoke and are at high risk for developing lung infections. We reported that cigarette smoke activates protein kinase C (PKC) and alcohol desensitizes ciliary beat frequency (CBF) to beta-agonists in bovine bronchial epithelial cells in vitro. The combined effect of smoke and alcohol exposure on...
متن کاملLaminin-332 alters connexin profile, dye coupling and intercellular Ca2+ waves in ciliated tracheal epithelial cells
BACKGROUND Tracheal epithelial cells are anchored to a dynamic basement membrane that contains a variety of extracellular matrix proteins including collagens and laminins. During development, wound repair and disease of the airway epithelium, significant changes in extracellular matrix proteins may directly affect cell migration, differentiation and events mediated by intercellular communicatio...
متن کاملImmune localization of calmodulin in the ciliated cells of hamster tracheal epithelium
Melachronous beating of cilia of epithelial surfaces of most respiratory airways moves the overlying mucous layer in a caudal direction. The molecular mechanisms controlling ciliary beat remain largely unknown. Calcium, an element in its cationic form, is ubiquitous in biological functions and its concentration is critical for ciliary beating. Calmodulin, a calcium-binding protein which regulat...
متن کاملMycoplasma hyopneumoniae increases intracellular calcium release in porcine ciliated tracheal cells.
We investigated the effects of intact pathogenic Mycoplasma hyopneumoniae, nonpathogenic M. hyopneumoniae, and Mycoplasma flocculare on intracellular free Ca2+ concentrations ([Ca2+]i) in porcine ciliated tracheal epithelial cells. The ciliated epithelial cells had basal [Ca2+]i of 103 +/- 3 nM (n = 217 cells). The [Ca2+]i increased by 250 +/- 19 nM (n = 47 cells) from the basal level within 10...
