    Notes: Two-component regulatory systems, typically composed of a sensor kinase to detect a stimulus and a response regulator to execute a response, are widely used by microorganisms for signal transduction. Response regulators exhibit a high degree of structural similarity and undergo analogous activating conformational changes upon phosphorylation. The activity of particular response regulators can be increased by specific amino acid substitutions, which either prolong the lifetime or mimic key features of the phosphorylated state. We probed the universality of response regulator activation by amino acid substitution. Thirty-six mutations that activate 11 different response regulators were identified from the literature. To determine whether the activated phenotypes would be retained in the context of a different response regulator, we recreated 51 analogous amino acid substitutions at corresponding positions of CheY. About 55% of the tested substitutions completely or partially inactivated CheY, ≈ 30% were phenotypically silent, and ≈ 15% activated CheY. Three previously uncharacterized activated CheY mutants were found. The 94NS (and presumably 94NT) substitutions resulted in resistance to CheZ-mediated dephosphorylation. The 113AP substitution led to enhanced autophosphorylation and may increase the fraction of non-phosphorylated CheY molecules that populate the activated conformation. The locations of activating substitutions on the response regulator three-dimensional structure are generally consistent with current understanding of the activation mechanism. The best candidates for potentially universal activating substitutions of response regulators identified in this study were 13DK and 113AP.

    Notes: Abstract The high mortality associated with current therapeutic approaches to nosocomial pneumonia has motivated consideration of newer immunologic approaches to prevention or therapy of this infection. Serotype specific vaccines, hyperimmune immunoglobulins, and monoclonal antibodies have been developed for certain problematic pathogens.Pseudomonas aeruginosa has been the major focus of this approach, and trials of hyperimmune anti-Ps. aeruginosa globulins for treatment of pneumonia are underway. Broad-spectrum, anti-lipopolysaccharide antibody preparations have also been employed for prophylaxis of nosocomial pneumonia, but to date these trials have not been successful. Finally, anticytokine antibody therapy to reduce infection-initiated inflammatory lung damage is under consideration.

    Description / Table of Contents: Summary A guinea pig model of experimentalPseudomonas aeruginosa pneumonia was used to evaluate factors affecting the efficacy of passive immune therapy with Psomaglobin®N, a hyperimmuneP. aeruginosa globulin. Animals treated 2 h after infection with a single intravenous infusion of Psomaglobin®N, 500 mg/kg, demonstrated 33% survival. Lower dosages were less effective and no survivors occurred among albumin-treated controls. Treatment with Psomaglobin®N was effective if given 2 h or 8 h after infection but not if delayed until 24 h after infection. Animals rendered neutropenic with cyclophosphamide did not survive if treated with Psomaglobin®N alone. However, when Psomaglobin®N was added to tobramycin treatment, a significant increase in survival occurred (86%) as compared to that observed with tobramycin alone (43%) (p 〈 0.05). We conclude that Psomaglobin®N may offer a useful therapeutic option in management ofP. aeruginosa pneumonia.
    Notes: Zusammenfassung An einem Meerschweinchenmodell der experimentellenPseudomonas aeruginosa-Pneumonie wurden die Faktoren untersucht, die die Wirksamkeit einer passiven Immunisierung mit Psomaglobin®N*, einem i.v.Pseudomonas-Immunglobulin, beeinflussen. Tiere, die 2 Stunden nach Infektion mit einer einmaligen intravenösen Infusion von Psomaglobin®N in einer Dosis von 500 mg/kg behandelt wurden, wiesen eine Überlebensrate von 33% auf. Geringere Dosen waren weniger wirksam. Keines der mit Albumin behandelten Kontrolltiere überlebte. Die Therapie mit Psomaglobin®N war wirksam, wenn sie 2 Stunden oder 8 Stunden nach der Infektion einsetzte. Begann sie erst 24 Stunden nach der Infektion, so zeigte sie dagegen keine Wirkung mehr. Neutropenische Tiere (vorangegangene Cyclophosphamid-Behandlung) überlebten nach alleiniger Behandlung mit Psomaglobin®N nicht. Bei kombinierter Therapie mit Psomaglobin®N und Tobramycin stieg die Überlebensrate im Vergleich zu einer alleinigen Tobramycin-Behandlung jedoch signifikant auf 86% gegenüber 43% (p 〈 0,05). Diese Befunde erlauben den Schluß, daß die Gabe von Psomaglobin®N eine wirksame Therapie derP. aeruginosa-Pneumonie sein könnte.
