Abstract

The role of (−) deprenyl in offering neuroprotection to cortical neurons exposed to Aluminium chloride (AlCl3) was examined. Primary cortical cultures derived from newborn rats were exposed to AlCl3on 6th day in vitro, at 100, 200, 400, 600, 800 and 1000 μM concentrations of AlCl3. After 48 h of AlCl3exposure, many nerve cell bodies were swollen; a beading of neurites and a disruption of the neuritic network were also observed suggesting neurodegeneration. Lactate dehydrogenase (LDH) efflux increased in a dose-dependent manner (59-120%). (−) Deprenyl co-exposure at concentrations of 10-7, 10-8 and 10-9M significantly attenuated both the morphological alterations and the LDH efflux induced by AlCl3. This in vitro study has demonstrated that (−) deprenyl can protect neurons from aluminium induced neurotoxicity.
