Factor neurotrophicus
Factores neurotrophici sunt familia biomolecularum—paene omnibus inter peptida et parva proteina ductis—quae incrementum, salutem, et differentationem neuronorum crescentium et  maturantium sustinent. Ita factores neurotrophici momentum non solum procreationis systematis nervosi habent, sed etiam eius maturitatis et plasticitatis.

Plerique factores uni ex tribus familiis attribuuntur:
 neurotrophinis
 ligandis factoris neurotrophici lineae cellularum glialium derivati
 cytokinis neuropoieticis

Neurotrophina 
Neurotrophina sunt proteina incrementi neuronorum, procreationis, et functionum. Inter quae numerantur factor auctus nervorum, factor neurotrophicus cerebro derivatus, neurotrophinum 3 ("neurotrophinum tres"), neurotrophinum 4 ("neurotrophinum quattuor"), dehydroepiandrosteronum, dehydroepiandrosteronum sulfuricum. Inter eorum receptoria numerantur receptoria factoris auctus nervi affinitatis exiguae et receptoria Trk.
