Growth regulation by nerve growth factor

Abstract

Although a great deal of descriptive information has been obtained about the actions of nerve growth factor on its target tissues, its structure, its receptors, and even its biosynthesis, there is no clear understanding, as yet, of the intracellular events mediating its transcriptional involvements. Work in this laboratory over the past five years has uncovered a number of nerve growth factor-initiated intracellular changes in sympathetic neurons and other nerve growth factor-sensitive systems, and has provided a framework into which they might fit. This article is written in an attempt to collect the data in a single communication and to suggest at least one mechanism by which the nerve growth factor may work.
