That was because that NGF could protect nerve cells, inhibit cerebral injury induced neuronal death, promote the growth of nerve cells and the proliferation of
neurogliocyte, and increase the communication between synapse.16
We know that about 20% of total body cholesterol is found in the brain, specifically in the
neurogliocyte membranes, which provide structural and metabolic support to the neurons.
Axon regeneration and pathfinding after damage involves a complex mechanism involving axon cross-talk with
neurogliocytes, nerve growth factors, neurotrophic factors, and receptors (6, 7).
