Ligand-induced assembly of antibody variable fragments for the chemical regulation of biological processes.
Article in Cell chemical biology, 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
Precise control of biological processes by the application of small molecules can increase the safety and efficiency of therapies. Adverse side effects of small molecule signals and/or immunogenicity of regulatory domains hinder their biomedical utility. Here, we designed small molecule-responsive switches, based on the conditional reassembly of human antibody variable fragments, called Fv-CID switches. The principle was validated using high-affinity antibodies against nicotine and β-estradiol to construct chemically responsive transcription factors. Further, we developed an Fv-CID switch responsive to bio-inert, clinically approved compound fluorescein, which was used to control the activity of chimeric antigen receptor (CAR) T cells and bispecific T cell engagers (BiTEs) in vivo. This study provides a framework to regulate the expression of endogenous genes, combine multiple chemical signals, and regulate T cell-based immunotherapy in an animal cancer model using a clinically approved small molecule regulator that could be customized for regulating therapeutic proteins or cells.
