MicroRNA-669f-5p targeting deoxycytidinephosphate deaminase contributes to sevoflurane-induced cognitive impairments in aged mice via the TLR2/4–MyD88–NF-κB pathway

MicroRNA-669f-5p contributes to sevoflurane-induced cognitive impairment in aged mice by targeting Dctd and activating the TLR2/4-MyD88-NF-κB pathway. These findings provide new insights into potential therapeutic strategies for anaesthesia-related POCD.
