Manganese (Mn) accumulates in the central nervous system and can cause neurotoxicity, but mechanisms of Mn-induced neurotoxicity remain unclear. We performed single-cell RNA sequencing (scRNA-seq) zebrafish brain after Mn exposure identified 10 cell types by marker genes: cholinergic neurons, dopaminergic (DA) glutaminergic GABAergic neuronal precursors, other microglia, oligodendrocyte, radial glia, undefined cells. Each type has its distinct transcriptome profile. Pseudotime analysis revealed that DA neurons had a critical role neurological damage. Combined with metabolomic data, chronic significantly impaired amino acid lipid metabolic processes brain. Furthermore, we found disrupted ferroptosis signaling pathway zebrafish. Overall, our study employed joint multi-omics is novel potential mechanism neurotoxicity.
