A growing body of evidence suggests that neurotrophic factors can protect neurons against neuronal death. In the present study we examined whether systemic administration of members of the neurotrophin family, nerve growth factor (NGF), brain derived neurotrophic factor (BDNF), neurotrophin 3 (NT-3) and neurotrophin 5 (NT-5) and basic fibroblast growth factor (bFGF) could protect against 1-methyl-4-phenylpyridinium (MPP+) induced striatal damage in neonatal rats. Systemic administration of NGF, BDNF and NT-5 produced significant neuroprotective effects, whereas NT-3 was ineffective. Systemic administration of bFGF had significant neuroprotective effects as assessed by T2-weighted magnetic resonance imaging and measurements of n-acetylaspartate and lactate using chemical shift magnetic resonance imaging. Systemic administration of NGF, BDNF and bFGF, but not NT-3 attenuated MPP+ induced increases in hydroxyl radical generation as assessed by the conversion of salicylate to 2,3- or 2,5-dihydroxybenzoic acid (DHBA). These results show that systemic administration of several neurotrophins and bFGF can attenuate neuronal damage induced by chemical hypoxia in vivo by a mechanism which may involve attenuation of oxidative stress.

D015655 1-Methyl-4-phenylpyridinium An active neurotoxic metabolite of 1-METHYL-4-PHENYL-1,2,3,6-TETRAHYDROPYRIDINE. The compound reduces dopamine levels, inhibits the biosynthesis of catecholamines, depletes cardiac norepinephrine and inactivates tyrosine hydroxylase. These and other toxic effects lead to cessation of oxidative phosphorylation, ATP depletion, and cell death. The compound, which is related to PARAQUAT, has also been used as an herbicide.

D019208 Brain-Derived Neurotrophic Factor A member of the nerve growth factor family of trophic factors. In the brain BDNF has a trophic action on retinal, cholinergic, and dopaminergic neurons, and in the peripheral nervous system it acts on both motor and sensory neurons.
