Definition
Neurotrophic factors are a family of proteins that support the growth, survival, and synaptic plasticity of neurons. The two most commonly referenced on TruthTides are BDNF (brain-derived neurotrophic factor) and NGF (nerve growth factor), both of which are upregulated by Semax, a synthetic analog of ACTH(4-10) studied for neuroprotection, stroke recovery, and cognitive enhancement.
