A potent protective bispecific nanobody targeting Herpes simplex virus gD reveals vulnerable epitope for neutralizing.
Article in Nature communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Herpes simplex virus (HSV) causes significant health burden worldwide. Currently used antiviral drugs are effective but resistance can occur. Here, we report two high-affinity neutralizing nanobodies, namely Nb14 and Nb32, that target non-overlapping epitopes in HSV gD. Nb14 binds a neutralization epitope located in the N-A' interloop, which prevents the interaction between gD and gH/gL during the second step of conformational changes during membrane fusion after virus attachment. The bispecific nanobody dimer (Nb14-32-Fc) exhibits high potency in vitro and in vivo. Mechanistically, Nb14-32-Fc neutralizes HSVs at both the pre-and post-attachment stages and prevents cell-to-cell spread in vitro. Administration of Nb14-32-Fc at low dosage of 1 mg/kg provides 100% protection in an HSV-1 infection male mouse model and an HSV-2 infection female mouse model. Our results demonstrate that Nb14-32-Fc could serve as a promising drug candidate for treatment of HSV infection, especially in the cases of antiviral drug resistance and severe herpes encephalitis.
