3-Bromo-4,5-dihydroxybenzaldehyde Attenuates Allergic Contact Dermatitis by Generating CD4
Article in In vivo (Athens, Greece). The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
BACKGROUND/
aimRegulatory T cells (Tregs) play a crucial role in inflammatory responses by regulating the activity of various immune cells. M2 macrophages induced by IL-10 and TGF-β exhibit anti-inflammatory functions and induce Treg differentiation. Although the beneficial effects of 3-bromo-4,5-dihydroxybenzaldehyde (BDB) on various diseases have been widely reported, the mechanisms, through which it alleviates allergic contact dermatitis (ACD) via Tregs and macrophages, are not well understood. Therefore, this study aimed to explore whether BDB suppresses ACD and induces Treg generation. MATERIALS AND
methodsMice were sensitized with 1% dinitrochlorobenzene (DNCB), followed by the application of 0.3% DNCB to their ears every 3 days for 31 days. BDB (100 mg/kg) was administered orally once daily throughout the 31 days. Cytokine and transcription factor expression were analyzed via real-time PCR and western blotting, while CD4
resultsBDB exhibited therapeutic efficacy in mice with ACD. In this study, the administration of BDB promoted the upregulation of transforming growth factor beta (TGF-β)-dependent CD4
conclusionBDB augments M2 macrophage function and induction of Tregs confers effective protection against ACD in mice. Consequently, BDB may represent a promising therapeutic approach for the treatment of inflammatory skin diseases.
