Ferritin nanoparticles displaying rift valley fever virus glycoprotein elicit potent dendritic cell activation in vitro.
Article in Virology journal, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Rift Valley fever (RVF) is a mosquito-borne zoonosis of major concern for human and animal health, yet no licensed human vaccine exists. Here, we engineered a self-assembling nanoparticle vaccine candidate by genetically fusing the RVF virus glycoprotein Gn to the N-terminus of a hybrid bacterial ferritin, generating nanoparticles that display 24 copies of Gn on their surface. Cryo-electron microscopy at 6 Å resolution confirmed ordered and symmetric presentation of the antigens, consistent with the structural models of ferritin and Gn. When incubated with human monocyte-derived dendritic cells, the Gn-ferritin nanoparticles were efficiently internalized and induced robust expression of maturation markers (e.g., CD54, CD83, CD86) and secretion of pro-inflammatory cytokines (e.g., IL-1β, IL-6, IL-12p40, TNF-α), in contrast to soluble Gn or ferritin controls. These findings demonstrate that ferritin nanoparticles provide a structurally defined and immunologically active platform for RVF virus antigen display, establishing a foundation for the development of safe and effective subunit vaccines against this emerging pathogen.
