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

SLC15A4, an endolysosomal solute carrier family transporter, plays a critical role in TLR7/8/9-induced immune responses through assembling a complex with the downstream adaptor TASL in a conformation-dependent manner. Despite its close functional association and promising therapeutic potential in infections, tumors, and autoimmune diseases, the development of conformation-specific antibodies for human SLC15A4 (hSLC15A4) remains challenging. Here, using a systematic screening and validation approach, we identify a pair of conformation-selective antibodies, clones 107 and 235, targeting the endolysosomal lumen surface of hSLC15A4 with opposite conformation-regulatory activities. Specifically, clone 107 selectively binds to hSLC15A4 in a TASL binding-incompetent luminal-open state; whereas clone 235 stabilizes hSLC15A4 in a TASL binding-competent cytoplasmic-open state. Our research identifies antibodies that recognize distinct conformations of hSLC15A4, potentially enabling modulation of the TLR7/8/9 pathway and contributing to the development of targeted therapies and research tools selectively targeting hSLC15A4.
