Abstract

Background

Cadmium chloride (Cd) is a pervasive environmental heavy metal pollutant linked to mitochondrial dysfunction, memory loss, and genetic disorders, particularly in the context of neurodegenerative diseases like Alzheimer's disease (AD).

Methods

This study investigated the neurotherapeutic potential of vitamin B6 (Vit. B6) in mitigating Cd-induced oxidative stress and neuroinflammation-mediated synaptic and memory dysfunction. Adult albino mice were divided into four groups: Control (saline-treated), Cd-treated, Cd+Vit. B6-treated, and Vit. B6 alone-treated. Cd and Vit. B6 were administered intraperitoneally, and behavioral tests (Morris Water Maze, Y-Maze) were conducted. Subsequently, western blotting, antioxidant assays, blood glucose, and hyperlipidemia assessments were performed.

Results

Cd-treated mice exhibited impaired cognitive function, while Cd+Vit. B6-treated mice showed significant improvement. Cd-induced neurotoxic effects, including oxidative stress and neuroinflammation, were observed, along with disruptions in synaptic proteins (SYP and PSD95) and activation of p-JNK. Vit. B6 administration mitigated these effects, restoring synaptic and memory deficits. Molecular docking and MD simulation studies confirmed Vit. B6's inhibitory effect on IL-1β, NRF2, and p-JNK proteins.

Conclusion

These results highlight Vit. B6 as a safe therapeutic supplement to mitigate neurodegenerative disorders, emphasizing the importance of assessing nutritional interventions for combating environmental neurotoxicity in the interest of public health.
