Abstract
Purpose of review: This review explores the role of Vitamin D3 and its derivatives as inhibitors of pathological metabolic modifications in neurodegenerative diseases. The manuscript investigates how Vitamin D3 impacts neuronal calcium regulation, antioxidative pathways, immunomodulation, and neuroprotection during detoxification, beyond its known functions in intestinal, bone, and kidney calcium and phosphorus absorption, as well as bone mineralization.
Recent findings: Recent studies have highlighted the synthesis of the active metabolite 1,25(OH)2D3 (vitamin D) in glial cells via the hydroxylation process of CY-P24A1, an enzyme in the cytochrome P450 system in the brain. The effects of vitamin D occur through the vitamin D receptor (VDR), a nuclear steroid receptor, which has been identified in various brain regions, including the cerebellum, thalamus, hypothalamus, basal ganglia, hippocampus, olfactory system, temporal, and orbital regions. Neurodegeneration is primarily associated with oxidative stress, protein aggregation, neuroinflammation, mitochondrial dysfunction, apoptosis, and autophagy changes, all of which Vitamin D and VDR are believed to influence. Vitamin D and VDR are recognized as both environmental and genetic factors in the etiopathogenesis of neurodegenerative diseases such as Multiple Sclerosis (MS), Parkinson's Disease (PD), Alzheimer's Disease (AD), and Amyotrophic Lateral Sclerosis (ALS). A deficiency in Vitamin D is postulated to have detrimental effects on the brain and other diseases throughout various stages of life. This review consolidates findings from clinical and experimental studies, as well as past publications, focusing on the implications of Vitamin D deficiency in these neurodegenerative conditions. Current articles published in PubMed were extensively considered for this review.
期刊介绍：
This journal aims to provide comprehensive review articles that emphasize significant developments in nutrition research emerging in recent publications. By presenting clear, insightful, balanced contributions by international experts, the journal intends to discuss the influence of nutrition on major health conditions such as diabetes, cardiovascular disease, cancer, and obesity, as well as the impact of nutrition on genetics, metabolic function, and public health. We accomplish this aim by appointing international authorities to serve as Section Editors in key subject areas across the field. Section Editors select topics for which leading experts contribute comprehensive review articles that emphasize new developments and recently published papers of major importance, highlighted by annotated reference lists. We also provide commentaries from well-known figures in the field, and an Editorial Board of more than 25 internationally diverse members reviews the annual table of contents, suggests topics of special importance to their country/region, and ensures that topics and current and include emerging research.
