Pseudomonas exotoxin and recombinant immunotoxins derived from it. In cell-based assays, we could show that the protein expression, maturation, and activation of ADAM17 is upregulated upon infection of lung epithelial cells with, Pneumonia is a serious, life-threatening lung infection mainly characterized by an inflammation of the alveoli leading to various pathophysiologies such as respiratory failure, acute respiratory distress syndrome (ARDS) and sepsis [, Epithelial cells play a significant role throughout the steps of infection by secretion of complement proteins that bind infectious agents and promote phagocytosis [, ADAM proteases are type 1 transmembrane proteins regulating, for example, cell proliferation, cell migration, cell adhesion and proteolysis [, In the present study, we could show a pathogen-dependent regulation of ADAM17 in alveolar epithelial cells during infection with, Rabbit anti-human ADAM17 (C-terminus), and mouse anti-human CD9 were obtained from Invitrogen (Frankfurt, Germany). doi: 10.1093/clinids/5.supplement_5.s979. Online ahead of print. Garton, K.J. The data show a novel processing pathway for internalized ETA, involving cathepsinsB and D, resulting in the production of ETA fragments that may participate in cytotoxicity and mitochondrial dysfunction. PE-based immunotoxins such as the mesothelin-targeting immunotoxin SS1P or LMB-100 act through a pathway involving (1) binding to the target antigen and internalization, (2) processing and trafficking, (3) inhibition of protein synthesis, and (4) induction of apoptosis.

Cell-mediated cleavage of Pseudomonas exotoxin between Arg279 and Gly280 generates the enzymatically active fragment which translocates to the cytosol. the pathogenic bacterium that causes diphtheria. FOIA Diphtheria toxin is an exotoxin secreted by mainly by Corynebacterium diphtheriae but also by Corynebacterium ulcerans and Corynebacterium pseudotuberculosis. Zhang, Y.; Chertov, O.; Zhang, J.; Hassan, R.; Pastan, I. Cytotoxic activity of immunotoxin SS1P is modulated by TACE-dependent mesothelin shedding. The Pseudomonas exotoxin (or exotoxin A) is an exotoxin produced by Pseudomonas aeruginosa. The secreted pseudomonas exotoxin A (PE) toxin can be divided into three main structural and functional domains: the N terminal receptor (R) binding domain I, translocation (T) domain II and the catalytic (C) domain III (see 3D structure (PDB Entry: 1ikq). Long, C.; Hosseinkhani, M.R.

Diphtheria toxin (DT), secreted by lysogenic strains of Corynebacterium diphtheriae carrying the phage-encoded DT gene, was the first ADP-ribosylating toxin for which the molecular mechanism of action was elucidated (C ollier 1975; P appenheimer 1977), and for many years DT has served as an important model system for studying the pathogenesis of bacterial exotoxins (C ollier 1982; J acobson . Within the endocytic pathway, PE encounters the endoprotease furin, which cleaves at a site in domain II and separates the polypeptide backbone between the A and B fragments (4).

These agents reflect the current holes in our understanding of the immunotoxin mechanism and often in the mechanism of the synergistic agent. In 1890, Emil Adolf von Behring developed an anti-toxin based on the blood of horses immunized with attenuated bacteria. Produced in vivo during P. aeruginosa infections, exotoxin A apparently causes disease by inhibition of protein synthesis, direct cytopathic effects, and interference with cellular immune functions of the host. P-ExA (0.01-1 microgram ml(-1)) caused a dose-dependent decrease in HKPA-indu 1992 Dec 15;267(35):25396-401. Loss of diphthamide pre-activates NF-B and death receptor pathways and renders MCF7 cells hypersensitive to tumor necrosis factor. The mechanism of Pseudomonas exotoxin A action consists in catalytic ADP-ribosylation of eukaryotic elongation factor 2 with subsequent inhibition of protein translation. To understand how the 37-kDa fragment functions, we focused on the role of specific amino acids located near its NH2 terminus. Andersson, Y.; Juell, S.

Chloramphenicol and macrolides such as erythromycin, clarithromycin, and azithromycin also act at the 50s ribosomal subunit and may compete for binding at this site. After proteolysis, the COOH-terminal fragment reaches the endoplasmic reticulum by retrograde transport where it translocates to the cytosol and inhibits protein synthesis by ADP-ribosylating elongation factor 2.
