  • Title: Humoral Mediators of Remote Ischemic Conditioning: Important Role of eNOS/NO/Nitrite.
    Author: Hess DC, Hoda MN, Khan MB.
    Journal: Acta Neurochir Suppl; 2016; 121():45-8. PubMed ID: 26463921.
    Abstract:
    Remote ischemic conditioning (RIC) is a powerful cardioprotectant and neuroprotectant. The mechanism of protection likely involves circulating, blood-borne mediators that transmit the signal from the periphery to the brain. The neuroprotective effect of RIC may be partially related to improvements in cerebral blood flow (CBF). Nitrite is a key circulating mediator of RIC and may be a mediator of increased CBF and also mediate cytoprotection through its effects on nitrosylation of mitochondrial proteins such as complex I. Measuring plasma nitrite may serve as an important blood biomarker, and measuring CBF by techniques such as MRI arterial spin labeling (ASL) may be an ideal surrogate imaging biomarker in clinical trials of RIC.
