Reactome Research Spotlight
[Jan 8, 2026] In their December 2025 Journal of Virology article "Inhibition of type I interferon signaling is a conserved function of gamma-herpesvirus-encoded microRNAs", Fachko et al. examine how gamma-herpesviruses from non-human primates utilize viral microRNAs to suppress type I interferon signaling, a crucial antiviral defense pathway, thereby facilitating the establishment and maintenance of lifelong infections. Using functional assays and mutant viruses, the authors demonstrate that these microRNAs directly target interferon receptors and core JAK/STAT signaling components, reducing antiviral gene activation during both early and latent infection. Reactome pathway analysis identified interferon signaling as a primary target of viral microRNA activity and linked specific host genes to the biologically relevant immune pathways.
Why Reactome
Reactome is a free, open-source, curated and peer-reviewed pathway database. Our goal is to provide intuitive bioinformatics tools for the visualization, interpretation and analysis of pathway knowledge to support basic research, genome analysis, modeling, systems biology and education.
The development of Reactome is supported by grants from the US National Institutes of Health (U24 HG012198) and the European Molecular Biology Laboratory.
