The Developing Cerebellum as a Target for Toxic Substances: Protective Role of Antioxidants.

Cerebellar development begins during the late embryological period and continues to undergo organizational changes long after birth. The cerebellum is particularly susceptible to developmental abnormalities on exposure to oxidants and free radicals, thus leading to oxidative stress. Oxidative stress occurs when there is an imbalance between reactive oxygen species generation and antioxidant defences which may disrupt signalling pathways, leading to cerebellar anomalies and dysfunction. In this regard, this review assesses current research underlining the importance of the cerebellum, provides an update on substances affecting cerebellar development and highlights some promising antioxidants that may play a role in attenuating toxicity in the developing cerebellum. To accomplish this, the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) system was employed and key scientific databases such as Science Direct, PubMed, Scopus, Web of Science and Google Scholar were searched to explore and collect information on the cerebellum and the role of antioxidants during its development. Originally, 109 articles were obtained but 22 articles which met the inclusion criteria were selected for the review. These findings provide an updated compilation of antioxidants capable of attenuating oxidative damage in the developing cerebellum, thus allowing future interdisciplinary studies in the form of clinical applications for screening and possible development of novel therapeutic agents from the identified products. © 2021.
