nerve growth factor
nerve growth factor[′nərv ‚grōth ‚fak·tər] (neuroscience) A multimeric protein that promotes nerve cell growth and may protect some types of nerve cells from damage, including nerve cells in the cholinergic system. nerve growth factor
nerve growth fac·tor (NGF), a protein (MW about 27,000) that controls the development of sympathetic postganglionic neurons and possibly also sensory (dorsal root) ganglion cells in mammals; similar factors have been isolated from the venom of several species of snakes; it has been isolated from the submaxillary glands of male mice, and when it is injected into newborn animals, sympathetic ganglia become hyperplastic and hypertrophic; stimulates synthesis of nucleic acids and protein.nerve growth factorn. Abbr. NGF A protein that stimulates the growth of sympathetic and sensory nerve cells.nerve growth fac·tor (NGF) (nĕrv grōth fak'tŏr) A protein secreted by the neuron's target, critical for the survival and maintenance of sympathetic and sensory neurons. The movement of NGF from axon tip to soma is thought to be involved in the long-distance signaling of neurons; binds at least two receptors, which are capable of responding to this growth factor, TrkA (pronounced "Track A") and the LNGFR (for "low affinity nerve growth factor receptor") on the surface of cells. nerve growth factor A peptide substance that stimulates growth and differentiation of NEURONES in the sympathetic and sensory nervous system. Nerve growth factor has been found effective in promoting the healing of corneal ulcers due to loss of the sensory innervation of the cornea. Corneal transparency has been restored by this means.nerve growth factor (NGF) a protein required for the maintenance of some types of neurone such as sympathetic and sensory neurones. It is produced by some nerve cell target tissues, e.g. smooth muscle. NGF also stimulates the production of nerve cell processes from developing neurones.Nerve growth factorA protein resembling insulin that affects growth and maintenance of nerve cellsMentioned in: Numbness and TinglingFinancialSeefactorSee NGF
