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