Genetic manipulation of the RNA genomes by reverse genetics is a powerful tool to study the molecular biology and pathogenesis of RNA viruses. During construction of an infectious clone from a Vero cell-adapted coronavirus infectious bronchitis virus (IBV), we found that a G-C point mutation at

BACKGROUND Roflumilast is a therapeutic agent in the treatment of chronic obstructive pulmonary disease (COPD). It has antiinflammatory effects; however, it is not known whether it can affect a biologic pathway implicated in COPD pathogenesis and progression. The self-propagating

Using antibodies to basic and acidic proline-rich proteins (PRP) of salivary origin, we detected PRP immunoreactivity in serous cells of human nasal, laryngeal, and tracheobronchial glands by an immunoperoxidase technique. Immunoreactive PRP, detected by immunoblotting from SDS gels, were also found

With increasing air pollution, chronic bronchitis (CB) has become a major public health problem worldwide. Previous studies have shown beneficial effects of Bergenin (Ber) on chronic bronchitis. To facilitate understanding of the pathogenesis underlying CB as well as to elucidate the Ber therapeutic

Mutations in desmin gene have been identified in patients with cardiac and skeletal myopathy characterized by intracytoplasmic accumulation of desmin-reactive deposits and electron-dense granular aggregates. We characterized two new desminopathy families with unusual features of adult-onset, slowly

Localization of neutralizing, serotype specific epitopes of infectious bronchitis virus has been difficult because these epitopes are conformationally dependent. We identified amino acids involved in a serotype specific, conformationally dependent epitope by analysis of the S1 gene of 13 monoclonal

Cystine knot α-amylase inhibitors are cysteine-rich, proline-rich peptides found in the Amaranthaceae and Apocynaceae plant species. They are characterized by a pseudocyclic backbone with two to four prolines and three disulfides arranged in a knotted motif. Similar to other knottins, cystine knot

To examine the pathogenetic role of neutrophil elastase in airway hypersecretion, we have studied the novel inhibitor of this enzyme, [4-(4-bromophenylsulfonylcarbamoyl)benzoyl-L-valyl-L-proline 1 (RS)-(1-trifluroacetyl-2-methylprolyl)amide] (ICI 200, 355). This compound was a potent (Ki = 0.6 +/-

In the present study, one- and two-dimensional gel electrophoresis combined with high resolution Fourier transform-ion cyclotron resonance mass spectrometry (FT-ICR MS) have been applied as powerful approaches for the proteome analysis of surfactant proteins SP-A and SP-D, including identification

Human bronchial mucin from a patient suffering from chronic bronchitis was solubilized in aqueous solution containing sodium azide and protease inhibitors and purified by Sepharose 4B and 2B column chromatography. The mucin was further purified by cesium bromide density gradient centrifugation.

Cyprus is an island in the eastern Mediterranean basin inhabited by people of Caucasian extraction, mostly Greek-Cypriots. The most common inherited disease among Caucasians is cystic fibrosis (CF). Although no careful scientific study had ever been done the impression was that CF was extremely rare
