This study explores the effects of zinc water supplementation on autism-like behavior, seizure threshold, and neurogenesis in ASD model mice. The results show that zinc water supplementation for 6 weeks can prevent autism-like behavior, reduce susceptibility to seizures, and increase the proliferation of hippocampal progenitor cells in BTBR mice. However, it has less effect on mossy fiber sprouting and neural progenitor cell differentiation. The findings suggest that zinc water can reduce autism-like behavior in a partially inherited autism model mice by promoting hippocampal neural precursor cell proliferation and reversing hyperexcitability.
This study aims to explore the effects of zinc water on autism-like behavior, convulsion threshold, and neurogenesis in ASD model animals. This study used the young BTBR ASD mouse model to explore the effect of a 6-week zinc water supplementation on ASD-like behaviors such as repetitive behavior and social communication disorder, seizure threshold, and the correlation with excitability regulation. The mice were divided into four groups of normal controls (B6) and models (BTBR) who did and did not receive zinc supplementation in water (B6, B6 + zinc, BTBR, and BTBR + zinc). For morphological changes in the hippocampus, we selected two indicators: hippocampal mossy fiber sprouting and neurogenesis. ASD-like behavior testing, seizure threshold determination, Timm staining, and neurogenesis-related assays-represented by Ki67 and DCX-were performed after 6 weeks of zinc supplementation. Our results show that zinc water can prevent autism-like behavior, reduce susceptibility to convulsions, and increase the proliferation of hippocampal progenitor cells in BTBR mice but has less effect on mossy fiber sprouting and neural progenitor cell differentiation. Zinc water reduces autism-like behavior in a partially inherited autism model mice-BTBR-which may be associated with hippocampal neural precursor cell proliferation and reversed hyperexcitability.
