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

introductionThe nerve growth factor (NGF) is a crucial neurotrophic factor with the ability to induce neuronal differentiation. However, whether NGF-loaded exosomes (Exo-NGF) can alleviate neuropathic pain in chronic constriction injury (CCI) rats remains unclear.

methodsA neuropathic pain model was established using CCI rats. The pain was assessed using the von Frey test and the hot plate test. Exo-NGF was collected from HEK293 cells transfected with an NGF plasmid. The diameter of Exo-NGF was determined using transmission electron microscopy. Protein levels of inflammatory factors, including IL-18, IL-1β, and TNF-α, were measured using enzyme- linked immunosorbent assay, and their mRNA levels were evaluated using qPCR. The NODlike receptor family pyrin domain-containing protein 3 (NLRP3) protein levels were determined using immunostaining and Western blot.

resultsNGF protein and mRNA were highly expressed in Exo-NGF. The mRNA in Exo-NGF was successfully delivered into neural stem cells and promoted their differentiation. Injection of Exo- NGF into the spinal dorsal horn significantly alleviated mechanical allodynia and thermal hyperalgesia. Additionally, Exo-NGF reduced levels of IL-18, IL-1β, and TNF-α. NLRP3 and its key components, including apoptosis-associated speck-like protein and caspase-1, were also reduced by Exo- NGF treatment in CCI rats. DISCUSSION: Our findings highlight the therapeutic potential of exosome-based NGF delivery for treating chronic pain conditions.

conclusionExo-NGF significantly alleviates neuropathic pain by suppressing inflammation and NLRP3 activation.
