This model for host-directed pharmacological therapy is fully generalizable and can be deployed to identify drugs targeting host cell-based master regulator signatures induced by virtually any pathogen. Drugs were prioritized for evaluation based on their experimentally elucidated, context-specific mechanism of action determined by drug perturbations in appropriately matched cell lines. In contrast, none of the 12 drugs selected as potential negative controls showed significant antiviral effect. In their report, the scientists noted that overall, 15 of the 18 drugs (83%) predicted to be effective by their methodology induced significant reduction of SARS-CoV-2 replication, without affecting cell viability. Specifically, the model integrates both computational and experimental assays to: (a) identify regulatory network aberrations, at the transcriptional level (the Viral Checkpoint), induced by infecting viruses and (b) predict drugs capable of inhibiting viral replication and infectivity by counteracting the hijacking of host cell regulatory mechanisms required for viral Infection.

This is especially the case for identifying antiviral drugs that make infected host cells more resistant to viral infection-so-called "host-directed therapy" or HDT-and, thereby, have the potential to be effective as monotherapy or combination treatment to maximize the clinical effectiveness of FDA-approved drugs targeting the virus directly through alternate mechanisms.Īgainst this backdrop, DarwinHealth scientists and their international colleagues introduce and experimentally validate ViroTreat, a novel integrative, regulatory network-based experimental model that can be deployed for rapid identification of antiviral drugs targeting the host cell response to viral hijack within a cell system-wide context. Ratings for alternate listings (with a tour versus without) were aggregated to understand the impact of virtual tours on interest in the featured business.With the Covid pandemic still a significant issue in many countries-a situation compounded by mounting concern about recurrent surges attributable to such highly transmissible Omicron variants as BA.5, BA.2.75 and others-there remains an unmet need for developing and deploying antiviral drug discovery models that can accurately and expeditiously predict, validate, and leverage the potential therapeutic effects of both established and investigational agents that inhibit viral replication.After viewing each listing, respondents were instructed to rate their interest in booking a reservation.Note: Presentation of alternate listings were randomized evenly and consistently throughout the field.1 listing with a virtual tour + 1 listing without a virtual tour.1 hotel listing + 1 restaurant listing and.

Respondents were asked to view one of the different versions for each business (in a randomized order).Different versions of a local business listing (one for a hotel, the other for a restaurant) were created to include basic info, photos and/or a virtual tour (the same media were used to create each version).An online survey was conducted with consumers who had searched online for a restaurant or hotel within the previous 30 days (using any device).Ĭollected between July 21st and August 2nd, 2015.
