High thermostability improves neutralizing antibody responses induced by native-like HIV-1 envelope trimers.
Article in NPJ vaccines, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 25 papers.
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
Soluble HIV-1 envelope glycoprotein (Env) immunogens are a prime constituent of candidate vaccines designed to induce broadly neutralizing antibodies. Several lines of evidence suggest that enhancing Env immunogen thermostability can improve neutralizing antibody (NAb) responses. Here, we generated BG505 SOSIP.v9 trimers, which displayed virtually no reactivity with non-neutralizing antibodies and showed increased global and epitope thermostability, compared to previous BG505 SOSIP versions. Chemical crosslinking of BG505 SOSIP.v9 further increased the melting temperature to 91.3 °C, which is almost 25 °C higher than that of the prototype SOSIP.664 trimer. Next, we compared the immunogenicity of a palette of BG505-based SOSIP trimers with a gradient of thermostabilities in rabbits. We also included SOSIP.v9 proteins in which a strain-specific immunodominant epitope was masked by glycans to redirect the NAb response to other subdominant epitopes. We found that increased trimer thermostability correlated with increased potency and consistency of the autologous NAb response. Furthermore, glycan masking steered the NAb response to subdominant epitopes without decreasing the potency of the autologous NAb response. In summary, SOSIP.v9 trimers and their glycan masked versions represent an improved platform for HIV-1 Env based vaccination strategies.
