Neurotrophins and the primate central nervous system: a minireview.
The central nervous system (CNS) of primates is more complex than the CNS of other mammals. Details of the development and aging of the primate CNS have recently been revealed by various neurobiological techniques. It has become clear that the primate CNS has unique characteristics, for example, the capacity for the overproduction and elimination of fibers and synapses. Some differences have also been found in the distribution of and changes with development in levels of various neuroactive substances. Recent discoveries of a variety of neurotrophins in the mammalian CNS have led to research on the neurobiology of these molecules in the primate CNS. The distribution of and changes with development in levels of nerve growth factor (NGF) in the primate CNS are closely correlated with the cholinergic system of the basal forebrain. The administration of NGF into the monkey brain prevents the degeneration of the cholinergic neurons of the basal forebrain after axotomy, a result that suggests that neurotrophins might be very valuable agents for the future treatment of neurological diseases, such as Alzheimer's and Parkinson's diseases.
