MT-ND6 and Sepsis: In our study, we used a range of pro-inflammatory and anti-inflammatory cytokines that well known for a long time to classify the immune statues of all the patients with sepsis (9, 34, 35), and the results showed that the concentration of MT-ND6 was significantly elevated as the immunological reaction aggravated, especially in the patients with mixed immune phenotypes and the immunosuppression only phenotype.
