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

backgroundThe sterile alpha and HEAT/Armadillo motif (SARM) is the fifth Toll-like receptor (TLR) adaptor protein containing the Toll/interleukin-1 receptor (TIR) domain, which is highly enriched in the brain. Toxoplasma gondii (T. gondii) is an obligate intracellular parasitic protozoan that causes zoonotic toxoplasmosis, resulting in threats to human health, such as brain damage. Previous studies have shown that SARM plays crucial roles in cell death and triggers specific transcription programs of innate immunity in response to cell stress, viral, and bacterial infections. However, whether SARM is involved in T. gondii infection remains unclear.

methodsIn this report, quantitative real-time polymerase chain reaction (qPCR), western blot, flow cytometry, ethynyldeoxyuridine (EdU) assay, and enzyme-linked immunosorbent assay (ELISA) were used to explore the relationship between SARM and T. gondii.

resultsHere, we showed that T. gondii infection increased the expression of SARM in vitro and in vivo. SARM induced cell apoptosis during T. gondii infection, activating the mitochondrial apoptotic pathway, the endoplasmic reticulum stress (ER) pathway, and the mitogen-activated protein kinase (MAPK) signaling pathway, and prompting the production of reactive oxygen species (ROS). Furthermore, SARM participated in the regulation of the inflammatory response through the nod-like receptor pyrin domain 3 (NLRP3) inflammasome signaling pathway during T. gondii in vitro infection.

conclusionsThese results elucidate the relationship between SARM and T. gondii infection, suggesting that SARM may represent a potential target for T. gondii control.
