Abstract

Brain‑derived neurotrophic factor (BDNF) is a growth factor crucial for neuronal survival, while its role in subarachnoid hemorrhage (SAH)‑induced neuronal apoptosis remains unclear. The aim of the present study was to investigate whether administering exogenous BDNF can protect against neuronal apoptosis and neurological deficits following SAH in a rat model. The BDNF level was found to be significantly decreased in the basal cortex at 6, 12, 24, 48 and 72 h following SAH. Exogenous BDNF significantly decreased the expression of Bax and reduced activation of caspase‑3 and caspase‑9 and the number of apoptotic neurons. Moreover, exogenous BDNF treatment significantly improved the neurological deficits at 72 h and long‑term behavioral deficits (day 14) following SAH in a rat model. These findings indicate that exogenous BDNF attenuated SAH‑induced neuronal injury in rats.
