Postoperative cognitive dysfunction (POCD) is a serious issue following cardiopulmonary bypass (CPB), leading to problems like memory loss and trouble concentrating.*
-
Mesenchymal stem cells (MSCs) can be beneficial through their secretions, and this study focused on exosomes from antler MSCs (AMSCs) in the context of POCD in rats.*
-
The research found that AMSC-derived exosomes mitigated brain and neurological damage in CPB rats, potentially by inhibiting the TLR2/TLR4 signaling pathway, although this effect was reduced when a TLR2/TLR4 agonist was introduced.*
