Iron plays an essential role in various physiological processes. A disruption in iron homeostasis can lead to severe consequences, including impaired neurodevelopment, neurodegenerative disorders, stroke, and cancer. Interestingly, the link between mental health disorders and iron homeostasis has not received significant attention. Therefore, our understanding of iron metabolism in the context of psychological diseases is incomplete. In this review, we aim to discuss the pathologies and potential mechanisms that relate to iron homeostasis in associated mental disorders. We propose the hypothesis that maintaining brain iron homeostasis can support neuronal physiological functions by impacting key enzymatic activities during neurotransmission, redox balance, and myelination. In conclusion, our review highlights the importance of investigating the relationship between trace element nutrition and the pathological process of mental disorders, focusing on iron. This nutritional perspective can offer valuable insights for the clinical treatment of mental disorders.

Iron-Mediated Regulation in Adipose Tissue: A Comprehensive Review of Metabolism and Physiological Effects.

Curr Obes Rep

January 2025

Department of Endocrinology and Metabolism, Zhuhai People's Hospital (The Affiliated Hospital of Beijing Institute of Technology, Zhuhai Clinical Medical College of Jinan University), Zhuhai, China.

Purpose Of Review: Review the latest data regarding the intersection of adipose tissue (AT) and iron to meet the needs of AT metabolism and the progression of related diseases.

Recent Findings: Iron is involved in fundamental biological metabolic processes and is precisely fine-tuned within the body to maintain cellular, tissue and even systemic iron homeostasis. AT not only serves as an energy storage depot but also represents the largest endocrine organ in the human body, maintaining systemic metabolic homeostasis.

Ferroptosis is a classic type of programmed cell death characterized by iron dependence, which is closely associated with many diseases such as cancer, intestinal ischemic diseases, and nervous system diseases. Transferrin (Tf) is responsible for ferric-ion delivery owing to its natural Fe binding ability and plays a crucial role in ferroptosis. However, Tf is not considered as a classic druggable target for ferroptosis-associated diseases since systemic perturbation of Tf would dramatically disrupt blood iron homeostasis.

Ferroptosis, an iron-dependent form of programmed cell death driven by oxidative stress, plays a crucial role in the progression of Alzheimer's disease (AD). Aging diminishes antioxidant systems that maintain iron homeostasis, particularly affecting the glutathione peroxidase (GPX) system, leading to increased ferroptosis and exacerbated neurodegeneration and neuroinflammation in AD. Nuclear factor erythroid 2-related factor 2 (Nrf2) is a key transcription factor regulating genes involved in antioxidant defense and ferroptosis.

Background: Neurodegeneration is characterized by the progressive loss of neurons. However, the mechanisms by which neurons die in Alzheimer's disease (AD) remain elusive. Disrupted iron homeostasis is associated with accelerated cognitive decline, amyloid beta deposition, and AD progression, but its pathogenic relevance is poorly understood.

Background: Alzheimer's disease (AD) is a progressive neurodegenerative disease characterized by neuronal dysfunction leading to decreased memory and cognitive function. AD research has largely focused on the potential pathogenic role of two disease hallmarks: amyloid beta and phosphorylated tau. However, pharmacological interventions targeting these disease hallmarks have met with limited clinical trial success.
