1 · What the graph read from it

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.

2 · The registry

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 effective trafficking of dendritic cells (DCs) to the lymph nodes (LNs), orchestrated by CC-chemokine receptor 7 (CCR7) and its ligand CCL21, is essential for the success of DC-based immunotherapies. This study explores the potential of C21TP, a naturally occurring basic peptide derived from the C-terminal of CCL21, to enhance DC homing to the draining LNs in a murine model of DC migration. C21TP, containing three clusters of basic residues, significantly boosts CCL21-mediated signaling and chemotaxis of DCs in vitro. In vivo, DCs formulated with C21TP prior to injection migrated more efficiently to the draining LNs than DCs alone or DCs formulated with a mutated version of C21TP, harboring substitutions in key basic residues. Further studies are needed to evaluate the impact of C21TP on T-cell priming efficacy in the context of DC-based immunotherapies. Nonetheless, C21TP's ability to enhance lymph node homing of adoptively transferred cells without additional cellular modifications could offer a practical and scalable approach for advancing future DC-based vaccines.
