Acupuncture may increase PICK1-TLR4 complex formation, reduce plasma NSE levels and inhibit inflammatory reactions through the acetylcholine pathway, protect mitochondrial function by activating the Nrf-2/HO-1 pathway, increase p-eNOS, and reduce Aβ deposition, thus alleviating hippocampus damage during sepsis. Here, HMOX1 is linked to Sepsis.
