[PROBLEMS ASSOCIATED WITH THE DIAGNOSIS OF PROLONGED/CHRONIC COUGH IN CLINICAL SETTINGS].

Background: Many patients visit primary care clinics or local hospitals with a complaint of prolonged/chronic cough. Among the different types of chronic cough, cough variant asthma (CVA) and postinfectious cough may be the most common types, and their differential diagnosis is difficult. Some physicians tend to prescribe inhaled corticosteroids before establishing a definitive diagnosis.

Overexpression of microRNA-155 suppresses chemokine expression induced by Interleukin-13 in BEAS-2B human bronchial epithelial cells.

Background: MicroRNAs are non-coding small RNAs that regulate expression of target genes by binding to 3' untranslated regions. In this study, we used bronchial epithelial cells to investigate in vitro the role of the microRNA miR-155 in the expression of chemokines associated with airway inflammation. miR-155 has previously been reported to regulate allergic inflammation.
