Direct engulfment of synapses by overactivated microglia due to cadmium exposure and the protective role of Nrf2
Cadmium (Cd), a notorious environmental pollutant, has been linked to neurological disorders, but the underlying mechanism remains elusive.We aimed to explore the role of microglia in Cd-induced synaptic damages at environmentally relevant doses and whether microglia directly engulf synaptic structures.Nrf2 is deeply implicated in the status of mic
