Mesenchymal Stromal Cells Play an Analgesic Role Through a Npy2r Sensory Neuron-Mediated Lung-to-Brain Axis.
Article in Advanced science (Weinheim, Baden-Wurttemberg, Germany), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Mesenchymal stromal cells (MSC) have emerged as a promising therapeutic option for neuropathic pain (NP), but the mechanisms remain elusive. Using murine pain models, it is demonstrated that MSC effectively alleviates pain, with efficacy comparable to dexmedetomidine, a moderate analgesic. Mechanistically, peripheral delivery of MSC-activated pulmonary Npy2r-expressing vagal sensory neurons, which project to the nucleus tractus solitarius and ventral lateral periaqueductal gray area, drives analgesia via the vagal lung-to-brain pathway. Chemogenetic activation of Npy2r sensory neurons similarly ameliorates spared nerve injury (SNI)-induced mechanical allodynia and thermal hyperalgesia. Furthermore, it is found that MSC-derived extracellular ATP, released via pannexin1, activates Npy2r sensory neurons through purinergic receptor P2X2 (P2rx2). Strikingly, inhalation of a P2rx2 agonist produced significant therapeutic effects in SNI mice. Together, these findings reveal that Npy2r sensory neuron-mediated lung-brain axis underlies MSC-induced analgesia and highlight the potential of targeting body-brain pathways for novel NP treatments.
