The Galaxy platform for accessible, reproducible, and collaborative data analyses: 2024 update
YesGalaxy (https://galaxyproject.org) is deployed globally, predominantly through free-to-use services, supporting user-driven research that broadens in scope each year. Users are attracted to public Galaxy services by platform stability, tool and reference dataset diversity, training, support and integration, which enables complex, reproducible, shareable data analysis. Applying the principles of user experience design (UXD), has driven improvements in accessibility, tool discoverability through Galaxy Labs/subdomains, and a redesigned Galaxy ToolShed. Galaxy tool capabilities are progressing in two strategic directions: integrating general purpose graphical processing units (GPGPU) access for cutting-edge methods, and licensed tool support. Engagement with global research consortia is being increased by developing more workflows in Galaxy and by resourcing the public Galaxy services to run them. The Galaxy Training Network (GTN) portfolio has grown in both size, and accessibility, through learning paths and direct integration with Galaxy tools that feature in training courses. Code development continues in line with the Galaxy Project roadmap, with improvements to job scheduling and the user interface. Environmental impact assessment is also helping engage users and developers, reminding them of their role in sustainability, by displaying estimated CO2 emissions generated by each Galaxy job.NIH [U41 HG006620, U24 HG010263, U24 CA231877, U01 CA253481]; US National Science Foundation [1661497, 1758800, 2216612]; computational resources are provided by the Advanced Cyberinfrastructure Coordination Ecosystem (ACCESS-CI), Texas Advanced Computing Center, and the JetStream2 scientific cloud.

Mechanism of interferon stimulated gene induction in HIV-1 infected macrophages
Viruses manipulate the complex interferon and interferon stimulated gene (ISG) system in different ways. We have previously shown that HIV inhibits type I and III interferons in its key target cells but directly stimulates a subset of >20 ISGs in macrophages and dendritic cells many of which are antiviral. Here we examined the mechanism of induction of ISGs and showed this occurred in two phases. The first phase was transient (0-24hpi) induced mainly by extracellular vesicles, and one of its component proteins HSP90α, contained within the HIV inoculum. The second dominant and persistent phase (>48hpi) was induced via newly transcribed HIV RNA and sensed via RIGI, as shown by the reduction in ISG expression after the knock down of the RIGI adaptor, MAVS, by siRNA and the inhibition of both the initiation and elongation of HIV transcription, by shRNA transcriptional silencing. We further defined the induction pathway, showing sequential HIV RNA stimulation via Tat, RIGI, MAVS, IRF1 and IRF7 also identified by siRNA knockdown. IRF1 also plays a key role in the first phase. We also showed that the ISGs, IFITs 1-3 inhibited HIV production, measured as extracellular infectious virus. All induced antiviral ISGs probably lead to restriction of HIV replication in macrophages, contributing to a persistent, non-cytopathic infection while the inhibition of interferon facilitates spread to adjacent cells. Both may influence the size of macrophage HIV reservoirs in vivo. Elucidating the mechanisms of ISG induction may help devise immunotherapeutic strategies to limit the size of these reservoirs. IMPORTANCE HIV, like other viruses, manipulates the antiviral interferon and interferon stimulated gene (ISG) system to facilitate its initial infection and establishment of viral reservoirs. HIV specifically inhibits all type l and lll interferons in its target cells, including, macrophages, dendritic cells and T cells. It also induces a subset of over 20 ISGs of differing composition in each cell target. This occurs in two temporal phases in macrophages. Extracellular vesicles contained within the inoculum induced the first and transient phase of ISGs. Newly transcribed HIV RNA induced the second and dominant ISG phase and here the full induction pathway is defined. Therefore, HIV nucleic acids, which are potent inducers of interferon and ISGs, are initially concealed and antiviral ISGs are not fully induced until replication is well established. Theses antiviral ISGs may contribute to the persistent infection in macrophages and to the establishment of viral reservoirs in vivo.Najla Nasr, Abdullateef A. Alshehri, Thomas K.
