Dipeptidyl peptidase 4 as an injury-responsive protein in the mouse sciatic nerve.
Article in Molecules and cells, 2024. 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
Dipeptidyl peptidase 4 (DPP4) is a membrane-bound protease known for its roles in immunity and metabolism; however, its function in the nervous system remains largely unexplored. We found that DPP4 is predominantly expressed in the Schwann cells of the sciatic nerve, and its systemic depletion in postnatal mice resulted in a decline in motor function. Importantly, the inhibition of its proteolytic activity did not affect axon regeneration, indicating that DPP4's protease activity may not be directly involved in axon regeneration. Instead, we observed a reduction in DPP4 protein levels in the sciatic nerve after injury and increased in serum postinjury, suggesting that DPP4 may be shed into circulation, potentially mediating systemic responses following injury. These findings highlight DPP4's importance in sensory function and its potential role in systemic responses after peripheral nerve injury.
