Exploring the neuroprotective role of melatonin against nickel-induced neurotoxicity in the left hippocampus. Biometals 2024:10.1007/s10534-024-00618-w. [PMID: 39060834 DOI: 10.1007/s10534-024-00618-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2024] [Accepted: 06/15/2024] [Indexed: 07/28/2024]
Abstract
Previous studies have demonstrated that the hippocampus, a crucial region for memory and cognitive functions, is particularly vulnerable to adverse effects of exposure to heavy metals. Nickel (Ni) is a neurotoxic agent that, primarily induces oxidative stress, a process known to contribute to cellular damage, which consequently affects neurological functions. The antioxidant properties of melatonin are a promising option for preventing the adverse effects of Ni, especially by protecting cells against oxidative stress and related damage. In our investigation of the potential neuroprotective effects of melatonin against Ni-induced neurotoxicity, we chose to administer melatonin through intraperitoneal injection in rats following an intrahippocampal injection of Ni into the left hippocampus. This approach allows us a targeted investigation into the influence of melatonin on the neurotoxic effects of Ni, particularly within the crucial context of the hippocampus. In the present study, we demonstrated that melatonin efficiency reduced lactate dehydrogenase level, and preserved antioxidant enzyme activities in Ni-exposed hippocampal tissue. It also mitigated the decline in superoxide dismutase and catalase activities. On the other hand, melatonin could act directly by reducing reactive oxygen species Ni-induced overproduction. Taking to gather these two potential mechanisms of action could be responsible for the adverse effect of Ni on the behavioral alteration observed in our study. This study provides significant insights into the potential of melatonin to mitigate the detrimental effects of Ni on the brain, particularly into the hippocampal region, suggesting its possible implications for the treatment of neurological disorders related to Ni exposure.

Thiel A, Michaelis V, Restle M, Figge S, Simon M, Schwerdtle T, Bornhorst J. Single is not combined: The role of Co and Ni bioavailability on toxicity mechanisms in liver and brain cells. CHEMOSPHERE 2024; 357:142091. [PMID: 38648987 DOI: 10.1016/j.chemosphere.2024.142091] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/27/2023] [Revised: 03/15/2024] [Accepted: 04/18/2024] [Indexed: 04/25/2024]
Abstract
The two trace elements cobalt (Co) and nickel (Ni) are widely distributed in the environment due to the increasing industrial application, for example in lithium-ion batteries. Both metals are known to cause detrimental health impacts to humans when overexposed and both are supposed to be a risk factor for various diseases. The individual toxicity of Co and Ni has been partially investigated, however the underlying mechanisms, as well as the interactions of both remain unknown. In this study, we focused on the treatment of liver carcinoma (HepG2) and astrocytoma (CCF-STTG1) cells as a model for the target sites of these two metals. We investigated their effects in single and combined exposure on cell survival, cell death mechanisms, bioavailability, and the induction of oxidative stress. The combination of CoCl2 and NiCl2 resulted in higher Co levels with subsequent decreased amount of Ni compared to the individual treatment. Only CoCl2 and the combination of both metals led to RONS induction and increased GSSG formation, while apoptosis and necrosis seem to be involved in the cell death mechanisms of both CoCl2 and NiCl2. Collectively, this study demonstrates cell-type specific toxicity, with HepG2 representing the more sensitive cell line. Importantly, combined exposure to CoCl2 and NiCl2 is more toxic than single exposure, which may originate partly from the respective cellular Co and Ni content. Our data imply that the major mechanism of joint toxicity is associated with oxidative stress. More studies are needed to assess toxicity after combined exposure to elements such as Co and Ni to advance an improved hazard prediction for less artificial and more real-life exposure scenarios.

Abstract
Heavy metals, including lead (Pb), cadmium (Cd), arsenic (As), cobalt (Co), copper (Cu), manganese (Mn), zinc (Zn), and others, have a significant impact on the development and progression of neurodegenerative diseases in the human brain. This comprehensive review aims to consolidate the recent research on the harmful effects of different metals on specific brain cells such as neurons, microglia, astrocytes, and oligodendrocytes. Understanding the potential influence of these metals in neurodegeneration is crucial for effectively combating the ongoing advancement of these diseases. Metal-induced neurodegeneration involves molecular mechanisms such as apoptosis induction, dysregulation of metabolic and signaling pathways, metal imbalance, oxidative stress, loss of synaptic transmission, pathogenic peptide aggregation, and neuroinflammation. This review provides valuable insights by compiling the supportive evidence from recent research findings. Additionally, we briefly discuss the modes of action of natural neuroprotective compounds. While this comprehensive review aims to consolidate the recent research on the harmful effects of various metals on specific brain cells, it may not cover all studies and findings related to metal-induced neurodegeneration. Studies that are done using bioinformatics tools, microRNAs, long non-coding RNAs, emerging disease models, and studies based on the modes of exposure to toxic metals are a future prospect to be explored.

Neuron Protection by EDTA May Explain the Successful Outcomes of Toxic Metal Chelation Therapy in Neurodegenerative Diseases. Biomedicines 2022; 10:biomedicines10102476.

Abstract
Many mechanisms have been related to the etiopathogenesis of neurodegenerative diseases (NDs) such as multiple sclerosis, amyotrophic lateral sclerosis, Parkinson’s disease, and Alzheimer’s disease. In this context, the detrimental role of environmental agents has also been highlighted. Studies focused on the role of toxic metals in the pathogenesis of ND demonstrate the efficacy of treatment with the chelating agent calcium disodium ethylenediaminetetraacetic acid (EDTA) in eliminating toxic metal burden in all ND patients, improving their symptoms. Lead, cadmium, aluminum, nickel, and mercury were the most important toxic metals detected in these patients. Here, I provide an updated review on the damage to neurons promoted by toxic metals and on the impact of EDTA chelation therapy in ND patients, along with the clinical description of a representative case.
