Neural factors are a class of protein molecules with neurotrophic activity that can promote the survival and regeneration of nerve cells. At present, more and more neural factors have been found to play a neuroprotective role in stroke, brain injury and other diseases. Once peripheral nerves are injured, protecting neurons from apoptosis is a prerequisite for nerve regeneration. Exogenous neural factors can promote survival of different types of neurons. Recent studies have shown that the combined effect of multiple factors in repairing peripheral nerve injury is better than that of a single factor, because nerve injury can cause changes in the levels of multiple peripheral neurotrophic factors and their receptors, and participate in nerve repair together. Therefore, the combined action of nerve factors is more inclined to the actual state in the body and can improve the protective effect of neurons.
