Targeting PAD4: A Promising Strategy to Combat β-Cell Loss in Type 1 Diabetes.
Article in International journal of molecular sciences, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Peptidylarginine deiminase 4 (PAD4) catalyzes protein citrullination, a post-translational modification implicated in type 1 diabetes mellitus (T1DM). This study examined PAD4 expression and activity in the pancreas of streptozotocin (STZ)-induced diabetic Wistar rats. Animals were divided into three groups: (A) STZ-induced diabetic rats (60 mg/kg, i.p.), (B) non-diabetic controls, and (C) diabetic rats treated with Cl-amidine (5 mg/kg), a pan-PAD inhibitor, from week six post-induction. Analyses included PAD4 mRNA and protein expression, citrullinated histone H3 (CitH3), calcium concentration, and neutrophil elastase activity. Diabetic rats exhibited increased PAD4 expression, CitH3 levels, and NETosis markers, alongside reduced pancreatic calcium, suggesting calcium consumption during PAD4 activation. Cl-amidine treatment attenuated NETosis. These results implicate PAD4 in T1DM pathogenesis via NETosis and support the utility of STZ-induced diabetic rats as a model for PAD4-targeted studies. Cl-amidine may represent a promising therapeutic approach to reduce pancreatic inflammation in T1DM.
