SLPI (secretory leukocyte protease inhibitor) is a 107-residue non-glycosylated protease inhibitor, which inhibits a wide range of serine proteases, trypsin, chymotrypsin, neutrophil elastase, chymase and cathepsin G. X-ray crystallographic analyses have shown that SLPI comprises two separate domains of similar architecture [Grütter, Fendrich, Huber & Bode (1988), EMBO J. 7, 345-351] and the C-...
Alpha one antitrypsin protein (A1AT), is encoded on the SERPINA1 (serpin peptidase inhibitor, claude A, member 1 gene), (OMIM 107400), located on chromosome 14q32.1 and functions as inhibitor of the enzyme neutrophil elastase. People with a low serum level of this protein are described as having the alpha-1-antrypsin deficiency (A1ATD), (OMIM #613490), one of the most common heritable disorders...
It was hypothesized that neutrophil elastase released from activated neutrophils may play an important role in the pathogenesis of pulmonary fibrosis. In the present study, we measured the neutrophil elastase:alpha-1-proteinase inhibitor complex (E-PI) in serum and bronchoalveolar lavage fluid (BALF) in 26 patients with pulmonary fibrosis and evaluated the correlation between E-PI levels and se...
BACKGROUND The separation of emphysema from fibrosis is not as clear-cut as it was thought in early studies. These two pathologies may be present at the same time in human lungs and in mice either instilled with elastolytic enzymes or bleomycin or exposed to cigarette-smoke. According to a current view, emphysema originates from a protease/antiprotease imbalance, and a role for antiproteases ha...
BACKGROUND Invasion of mosquito salivary glands (SGs) by Plasmodium falciparum sporozoites is an essential step in the malaria life cycle. How infection modulates gene expression, and affects hematophagy remains unclear. PRINCIPAL FINDINGS Using Affimetrix chip microarray, we found that at least 43 genes are differentially expressed in the glands of Plasmodium falciparum-infected Anopheles ga...
To determine the effect of the antiallergic drug azelastine on airway mucosal inflammation, we studied airway microvascular permeability in response to platelet-activating factor (PAF) in pathogen-free rats. Vascular permeability and neutrophil accumulation were assessed by the percent area occupied by Monastral blue-labeled blood vessels and by myeloperoxidase-containing granulocytes, respecti...
CD43 (sialophorin, leukosialin), an O-glycosylated and sialylated membrane protein (surface sialomucin) with antiadhesive properties, is thought to protect circulating leukocytes by preventing cell surface interactions. Although it is resistant to several proteases, the granule enzyme elastase was recently implicated in loss of extracellular CD43 regions from incubated neutrophils. Flow cytomet...
Pneumoconiosis is defined as the disease resulting from a chronic exposure to different inorganic dusts. In order to assess the lung defence against the effects of dust exposure, we studied the bronchoalveolar lavage (BAL) fluids from 30 silicotic patients (9 of them having a diagnosis of progressive massive fibrosis (PMF)) and 8 subjects with a diagnosis of asbestosis. Total protein content, N...
