1 · What the graph read from it

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.

2 · The registry

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

African swine fever (ASF) is a significant threat to the global pig breeding industry, making the development of a vaccine extremely urgent. In this study, the key antigenic proteins p30 and p54 of African swine fever virus (ASFV) were fused with the Fc fragment of immunoglobulin (IgG) to construct recombinant fusion proteins with strong immunity. Here, we successfully expressed four recombinant fusion proteins comprising the ASFV proteins p30 and p54 (p30-54 and p54-30) alone and the porcine IgG Fc-fused p30 and p54 proteins (p30-54-Fc and p54-30-Fc) using an insect baculovirus expression system. All expressed proteins demonstrated excellent reactivity with specific antibodies, confirming their immunological activity. In vitro studies revealed that the Fc-fused proteins exhibited significantly increased binding affinity to Fcγ receptors (FcγRs) on antigen-presenting cells (APCs). Immunization studies in mice revealed that p30-54-Fc and p54-30-Fc elicited greater humoral and cellular immune responses than p30-54 and p54-30, respectively. Notably, sera from mice immunized with the Fc-fused proteins significantly inhibited ASFV-GFP infection in porcine alveolar macrophages. These results suggest that these ASFV p30-54-Fc and p54-30-Fc recombinant fusion proteins represent promising candidate antigens for the development of an effective ASF subunit vaccine. KEY POINTS: • Fc-fused ASFV p30/p54 proteins elicit stronger humoral and cellular immune responses in mice. • Sera from Fc-fused antigen-immunized mice show enhanced inhibition of ASFV infection in PAMs. • Fc fusion strategy improves immunogenicity of ASFV antigens, supporting promising subunit vaccine candidates.
