Discovery and molecular mechanism of potent neutralizing antibody from humanized mice with respiratory syncytial virus.
Article in PLoS pathogens, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Respiratory syncytial virus (RSV) is a leading cause of lower respiratory tract infections among infants and older adults, posing a significant threat to global public health. The prophylactic use of neutralizing antibodies (nAbs) underscores the need to understand elite RSV antibody neutralization mechanisms, which is fundamental for developing next-generation therapies with enhanced potency and broader activity. In this study, we utilized H2L2 transgenic mice encoding human immunoglobulin variable regions for immunization and successfully screened multiple antibodies with significant neutralizing activity using the Beacon Optofluidic system. One of these antibodies, PR306007, exhibited significantly superior broad-spectrum neutralization against both RSV-A and B subgroups. Cryo-electron microscopy (Cryo-EM) structural analysis revealed that PR306007 binds to a unique epitope that overlaps with antigenic sites II and V of the F protein, with its primary binding regions located at the base of the α6 and α7 helices of site II, and residues S173 and N175 of site V. This binding mode offers valuable insights into enhanced neutralization activity and potentially reduces the risk of emerging immune evasive mutants. Furthermore, PR306007 showed potent in vivo antiviral activity against RSV infection and demonstrated good efficacy against both lower and upper respiratory tract infections, making it a promising prophylactic candidate for broad prevention. These findings provide new insights for the future development of RSV vaccines or nAbs.
