Neuroglobin is a specific oxygen-binding globin protein first discovered in 2000 that has been verified to play an endogenous neuroprotective molecule against ischemia, hypoxia, oxidative stress damage, and related neurological disorders (Burmester et al., 2000; Qiu and Chen, 2014; Nair et al., 2018; Van Acker et al., 2018). Here, NGB is linked to nervous system disorder.
