Synergistic effects of fluticasone propionate and salmeterol on in vitro T-cell activation and apoptosis in asthma

2004

Background In asthma T cells are characterized by an increased activation state and by reduced apoptosis. Objective Because the clinical efficacy of inhaled corticosteroids combined with long-acting β 2 -agonists has been widely demonstrated in asthma, we studied, in vitro , the effect of fluticasone propionate (FP) and salmeterol alone and in combination on the activation and apoptosis of peripheral blood T cells (PBTs), on the expression of phosphorylated nuclear factor κB inhibitor (IκBα), and on the nuclear translocation of glucocorticoid receptor (GR) in PBTs from asthmatic subjects. Methods Apoptosis was evaluated on the basis of annexin V binding, whereas the expression of caspases 8…

Cigarette smoke alters non-neuronal cholinergic system components inducing MUC5AC production in the H292 cell line.

2013

Abstract Cigarette smoke extract (CSE) affects the expression of Choline Acetyl-Transferase (ChAT), muscarinic acetylcholine receptors, and mucin production in bronchial epithelial cells. Mucin 5AC (MUC5AC), muscarinic acetylcholine receptor M3, ChAT expression, acetylcholine levels and acetylcholine binding were measured in a human pulmonary mucoepidermoid carcinoma cell line (H292) stimulated with CSE. We performed ChAT/RNA interference experiments in H292 cells stimulated with CSE to study the role of ChAT/acetylcholine in MUC5AC production. The effects of Hemicholinium-3 (HCh-3) (50 μM) (a potent and selective choline uptake blocker) and Tiotropium bromide (Spiriva ® ) (100 nM), alone o…
