The role of zinc homeostasis in major depressive disorder: heterogeneous pathological mechanisms and therapeutic implications.
Review in Annals of medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
backgroundMajor depressive disorder (MDD) involves multifaceted pathologies including neurotransmission, neuroplasticity, inflammation, and hypothalamic-pituitary-adrenal (HPA) axis dysfunction. Growing evidence implicates zinc homeostasis imbalance in MDD, yet a systematic framework integrating it into these mechanisms is lacking.
methodsThis narrative review synthesizes literature (2000-2024) to elucidate the multidimensional associations between zinc homeostasis and MDD pathology, focusing on zinc's roles in neurotransmitter regulation, BDNF signaling, inflammation, oxidative stress, and HPA axis activity.
resultsEpidemiological studies indicate an inverse correlation between serum zinc levels and MDD. Mechanistically, zinc imbalance may disrupt neural signaling via glutamate/GABA/5-HT receptors, impair neurotrophy via BDNF, exacerbate neuroinflammation and oxidative stress, and promote HPA axis hyperactivity. Zinc supplementation shows efficacy in mild-to-moderate MDD and augments conventional antidepressants, especially in treatment-resistant cases. Novel targets like GPR39 and zinc transporters, along with brain-targeted formulations, offer promising therapeutic avenues.
conclusionsZinc homeostasis is critically involved in MDD's heterogeneous pathology, making it a promising target for precision treatment. However, this potential is tempered by inconsistent data and methodological limitations. Future research should prioritize: standardizing assessment methods; investigating brain region-specific zinc dynamics; developing novel targeted formulations; and exploring gene-environment interactions in zinc signaling.
