    摘要: Die Erfindung betrifft ein Verfahren zur Reduktion der Population mindestens einer intestinalen und/oder gastrointestinalen Bakterienart, welches die folgenden Schritte umfasst: a) Bereitstellen einer biologischen Probe, welche Bakterien mindestens einer intestinalen und/oder gastrointestinalen Bakterienart umfasst, wobei die intestinale und/oder gastrointestinale Bakterienart direkt oder indirekt eine psychische, neurodegenerative und/oder neurologische Erkrankung und/oder Störung eines Wirtsorganismus beeinflusst; und b) Bereitstellen von Bakteriophagen mindestens einer Bakteriophagenart, welche spezifisch für die intestinale und/oder gastrointestinale Bakterienart sind und welche mindestens eine funktionell mit einem Promotor und/oder einem regulatorischen Element verknüpfte Nukleinsäure umfassen, und c) In-Kontakt-bringen und Inkubieren der biologischen Probe mit den Bakteriophagen, wobei das Inkubieren bis zum Erreichen einer Reduktion der Population der intestinalen und/oder gastrointestinalen Bakterienart um mindestens 70% erfolgt.

    摘要: Broad spectrum antiviral peptides and composition including therapeutically effective amounts of the antiviral peptides along with a pharmaceutically acceptable carrier are provided. The antiviral compositions show a strong broad spectrum antiviral effect, without resulting to viral resistance. The antiviral compositions are useful for treatment of diseases caused by viral infections, particularly respiratory viruses such as enveloped coronaviruses (SARS-CoV-2, SARS-CoV and MERS-CoV), the pandemic A (H1N1) pdm09 virus, avian influenza A (H7N9) virus, and the non-enveloped rhinovirus.

    摘要: This disclosure provides compositions and methods for delivering a viral composition to cells, e.g., for cell surface receptor-mediated uptake, and enhanced viral transduction. Viral transduction can be achieved via a bifunctional bridging composition that includes a moiety that binds to a cell surface receptor ligand and a linked bridging moiety that binds to a viral composition. Also provided are modified viral compositions comprising a bridging composition specifically bound via its bridging moiety to the viral composition. Modified viral compositions and methods for reducing levels or titers of neutralizing antibodies in a subject in need of viral therapy, e.g., gene therapy, are provided. In some embodiments, the modified viral composition includes empty viral particles that bind and internalize neutralizing autoantibodies. Modified viral compositions including empty viral particles can be administered prior to viral therapy. Also provided are pharmaceutical compositions and kits including a bifunctional bridging composition and/or modified viral compositions.
