The Glutamate-Glutathione axis in neuropsychiatric disorders and cancer: From shared mechanisms to non-invasive biomarkers.
Review in Redox 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
Glutamate is the most abundant excitatory neurotransmitter in the central nervous system and a key non-essential amino acid in the body. It plays a central role in maintaining the excitatory-inhibitory balance of the nervous system, regulating systemic metabolic homeostasis, and participating in immune modulation. Additionally, it serves as a precursor for glutathione synthesis. Glutathione is a vital antioxidant and detoxifying molecule in organisms, capable of directly scavenging reactive oxygen species or toxic metabolites. Dysfunction of glutathione is associated with oxidative stress-related diseases. Given the critical roles of glutamate and glutathione in physiological and pathological states, we aim to systematically elucidates the metabolic interplay between glutamate and glutathione, referred to here as the Glutamate-Glutathione axis, as an integrative conceptual framework grounded in established biochemistry. By detailing the metabolic interplay of glutamate and glutathione, this review explores their mutually influential mechanisms. Furthermore, it summarizes the relevant signaling pathways and regulatory mechanisms within the Glutamate-Glutathione axis, clarifying its pivotal role in disease pathogenesis, with a particular focus on neuropsychiatric disorders and cancer. Finally, we aim to review non-invasive methods for detecting glutamate and glutathione using magnetic resonance imaging and presents our specialized sequence. This approach aims to provide a valuable non-invasive imaging tool for early diagnosis, efficacy evaluation, and therapeutic target development in related diseases. By integrating foundational metabolic networks, molecular regulatory mechanisms, disease associations, and clinical detection techniques, this review aim to establish the research framework of the Glutamate-Glutathione axis, fostering deeper integration and advancement from bench to bedside in this field.
