Exposure to silver nanoparticles primes mast cells for enhanced activation through the high-affinity IgE receptor.
Article in Toxicology and applied pharmacology, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
Mast cells are a key effector cell in type I allergic reactions. It has been shown that environmental exposures such as diesel exhaust and heavy metals exacerbate mast cell degranulation and activation. Today, the use of engineered nanomaterials (ENMs) is rapidly expanding and silver nanoparticles (AgNP) are one of the mostly widely utilized ENMs, primarily for their antimicrobial properties, and are being incorporated into many consumer and biomedical products. We assessed whether pre-exposure of bone marrow-derived mast cells (BMMCs) to 20 nm AgNPs enhanced degranulation and activation to an allergen (dinitrophenol-conjugated human serum albumin) by measuring β-hexosaminidase release, LTB4 and IL-6 production. In addition, we assessed reactive oxygen species (ROS) generation, cell oxidative stress and toxicity as well as total and individual protein tyrosine phosphorylation (p-Tyr). We found that pre-exposure of BMMCs to AgNPs results in exacerbated allergen-mediated mast cell degranulation, LTB4 production and IL-6 release. Exposure of BMMCs to AgNPs exacerbated allergen-induced ROS generation, however, this was not associated with oxidative stress nor cell death. Finally, pre-exposure to AgNPs enhanced allergen-mediated global p-Tyr as well as individual proteins including Syk, PLC
