Nerve Growth Factor Signaling Pathway
Nerve growth factor (NGF) is one of the most important biologically active molecules
in the nervous system. It plays an important role and has clinical significance in
regulating the growth, development, differentiation, survival of nerve cells and the
regeneration and repair of injured nerves. Current basic research indicates that NGF
can be applied to neurotoxicity, peripheral nerve injury, diabetic peripheral
neuropathy, senile dementia, Parkinson's disease, facial neuritis, and nerve damage
(including spinal cord injury, high paraplegia, finger replantation, and neurological
diseases). Brain damage and other peripheral nervous system damages are the only
neurological protein factors currently available for clinical use. NGF has been in the
historical process of early discovery to medical applications for more than half a
century. Human nerve growth factor (hNGF) is a biologically active factor found in the
human body that has a trophic effect on normal nerve cells and regulates the
function of damaged nerve repair. It can maintain the survival of sympathetic and
sensory nerves and promote nerve cells. The differentiation determines the direction
of axon stretching and plays a decisive role in promoting brain development, nervous
system growth, damage nerve regeneration and functional recovery.
Nerve growth factor family
NGF is synthesized as precursor in vivo, including signal peptides, leader peptides,
and mature peptides. The signal peptide contributes to protein secretion. Two
conserved regions in the leader peptide are required for NGF expression, enzymatic
hydrolysis to form biologically active proteins, and secretion of mature NGF. It has
now been found that leader peptides also contribute to the correct folding of
proteins, and such leader peptides are known as molecular chaperones (IMCs).
Therefore, it is considered that the leader peptide may play an intramolecular
molecular chaperone role in the folding process of NGF. ProNGF contains a potential
N-glycosylation site, and studies by Seidah et al. have shown that the propeptide
portion of the NGF precursor can be N-glycosylated, and the glycosylation of proNGF
helps to secrete the endoplasmic reticulum. ProNGF undergoes post-translational
modifications at the N-terminus and C-terminus to form biologically active mature
NGF.
