Leucine deprivation results in antidepressant effects via GCN2 in AgRP neurons.
Article in Life metabolism, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
Essential amino acids (EAAs) are crucial nutrients, whose levels change in rodents and patients with depression. However, how the levels of a single EAA affects depressive behaviors remains elusive. Here, we demonstrate that although deprivation of the EAA leucine has no effect in unstressed mice, it remarkably reverses the depression-like behaviors induced by chronic restraint stress (CRS). This beneficial effect is independent of feeding and is applicable to the dietary deficiency of other EAAs. Furthermore, the effect of leucine deprivation is suppressed by central injection of leucine or mimicked by central injection of leucinol. Moreover, hypothalamic agouti-related peptide (AgRP) neural activity changes during CRS and leucine deprivation, and chemogenetically inhibiting AgRP neurons eliminates the antidepressant effects of leucine deprivation. Finally, the leucine deprivation-regulated behavioral effects are mediated by amino acid sensor general control non-derepressible 2 (GCN2) in AgRP neurons. Taken together, our results suggest a new drug target and/or dietary intervention for the reduction of depressive symptoms.
