Light chain of a public SARS-CoV-2 class-3 antibody modulates neutralization against Omicron.
Article in Cell reports, 2023. 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
The pairing of antibody genes IGHV2-5/IGLV2-14 is established as a public immune response that potently cross-neutralizes SARS-CoV-2 variants, including Omicron, by targeting class-3/RBD-5 epitopes in the receptor binding domain (RBD). LY-CoV1404 (bebtelovimab) exemplifies this, displaying exceptional potency against Omicron sub-variants up to BA.5. Here, we report a human antibody, 002-S21B10, encoded by the public clonotype IGHV2-5/IGLV2-14. While 002-S21B10 neutralized key SARS-CoV-2 variants, it did not neutralize Omicron, despite sharing >92% sequence similarity with LY-CoV1404. The structure of 002-S21B10 in complex with spike trimer plus structural and sequence comparisons with LY-CoV1404 and other IGHV2-5/IGLV2-14 antibodies revealed significant variations in light-chain orientation, paratope residues, and epitope-paratope interactions that enable some antibodies to neutralize Omicron but not others. Confirming this, replacing the light chain of 002-S21B10 with the light chain of LY-CoV1404 restored 002-S21B10's binding to Omicron. Understanding such Omicron evasion from public response is vital for guiding therapeutics and vaccine design.
