Abstract: Perinatal brain injury is a major public health issue and is a leading cause of neonatal mortality and morbidity (Liu et al., 2016). It may lead to developmental impairment and permanent neurological deficits, such as cerebral palsy and mental retardation (Lally et al., 2019; Juul et al., 2020). Among many etiological factors, hypoxic-ischemic encephalopathy (HIE) in term infants and intraventricular/periventricular hemorrhage in preterm infants are the most common causes of perinatal brain damage (Hagberg et al., 2015). The different etiological factors during critical developmental periods can lead to a common pathway of perinatal brain injury marked by neuronal excitotoxicity, cellular apoptosis, and microglial activation (Hagberg et al., 2014; Wu et al., 2019). Apoptosis has been found more prominent in the immature brain compared to the mature brain (Zhu et al., 2005). Some clinical studies have shown promising results for perinatal brain injury (Zhu et al., 2009a; Azzopardi et al., 2016); however, widely accepted clinically efficient therapy is still limited (Tagin et al., 2015; Hagberg et al., 2016). Thus, there is a pressing need for a better understanding of the mechanisms of neuronal cell death and perinatal brain injury and for conducting comparative and translational studies on how to reduce neuronal cell death, increase cell survival, and promote brain regeneration and repair after injury. Perinatal hypoxia-ischemia (HI)-induced brain injury is one of the most common forms of neonatal brain injury, which is more common in the developing countries (Liu et al., 2016). Thus, we focus on the molecular mechanisms of hypoxic-ischemic brain injury in this review, specifically the importance of apoptosis-inducing factor (AIF) as a key protein for finding new therapeutic strategies for preventing perinatal brain injury.
