Astrocytes mediate a positive feedback loop for oxytocin.
Article in bioRxiv : the preprint server for biology, 2026. 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
Social interactions are critical for well-being and survival. Oxytocin neurons in the paraventricular nucleus of the hypothalamus help regulate social behaviors in many species, and respond to social stimuli to promote pro-social interactions. Here, we show that chronic social isolation reduced production of oxytocin peptide, and led to a delay in the onset of huddling behavior upon resocialization in male mice. Exogenous oxytocin treatment prevented both the behavioral and molecular effects of social deprivation. Using conditional knockouts, we found that oxytocin-induced oxytocin expression was mediated by local hypothalamic astrocytes. Oxytocin signaling in astrocytes upregulated the expression of a retinoic acid-synthesizing enzyme Aldh1a1, and retinoic acid increased oxytocin expression. These findings reveal a mechanism in which astrocytes can sense and control neuropeptide levels to influence social behaviors.
