Positive and negative cis-acting regulatory sequences control expression of leukotoxin in Actinobacillus actinomycetemcomitans 652.
Integration of IS1301 into an AT-rich inverted repeat located upstream of the ltx operon was previously shown to confer a hyperleukotoxic phenotype in Actinobacillus actinomycetemcomitans IS1 (T. He, T. Nishihara, D. R. Demuth, and I. Ishikawa, J. Periodontol. 70:1261-1268, 1999), but the mechanism leading to increased leukotoxin production was not determined. We show that an IS1 ltx promoter::...
متن کاملSecretion of RTX leukotoxin by Actinobacillus actinomycetemcomitans.
Actinobacillus actinomycetemcomitans, the etiologic agent for localized juvenile periodontitis and certain other human infections, such as endocarditis, expresses a leukotoxin that acts on polymorphonuclear leukocytes and macrophages. Leukotoxin is a member of the highly conserved repeat toxin (RTX) family of bacterial toxins expressed by a variety of pathogenic bacteria. While the RTX toxins o...
متن کاملImmunosuppressive properties of Actinobacillus actinomycetemcomitans leukotoxin.
Actinobacillus actinomycetemcomitans produces a leukotoxin that kills human polymorphonuclear cells (PMNs) and monocytes but not lymphocytes. In this study, we examined A. actinomycetemcomitans leukotoxin for its ability to alter human peripheral blood lymphocyte (HPBL) responsiveness. After a 90-min exposure to the leukotoxin, all monocytes were killed and HPBL responsiveness to mitogens and a...
متن کاملBasal expression of the histone H5 gene is controlled by positive and negative cis-acting sequences.
Sequences from -3500 to +1365 of the chicken histone H5 gene have been analyzed for the presence of cis-acting elements in H5 expressing (transformed CFU-E) and non-expressing cells (fibroblasts). The region from -3500 to -115 had little effect on transcription. Proximal upstream sequences contain a negative element (UNE, -115 to -95), capable to also repress the activity of the heterologous HS...
متن کاملLytic effects of Actinobacillus actinomycetemcomitans leukotoxin on human neutrophil cytoplasts.
Actinobacillus actinomycetemcomitans leukotoxin lysed human neutrophil cytoplasts. The reaction was associated with a rapid influx of extracellular calcium, a collapse in membrane potential, release of lactate dehydrogenase, and overt disintegration of the plasma membrane. These functional and structural alterations in the plasmalemma of neutrophil cytoplasts reinforce the hypothesis that A. ac...
