The neurotrophic hypothesis: where does it stand?
The neurotrophic hypothesis provides an explanation for how target fields influence the size of the neuronal populations that innervate them. This hypothesis arose from work on nerve growth factor (NGF), the founder member of the neurotrophin family of secreted proteins. Its principal tenet is that the survival of developing neurons depends on ...
Neurotrophic hypothesis of depression
The neurotrophic hypothesis of depression [1] proposes that major depressive disorder (MDD) is caused, at least partly, by impaired neurotrophic support. Neurotrophic factors (also known as neurotrophins) are a family of closely related proteins which regulate the survival, development, and function of neurons in both the central and peripheral ...

Major depressive disorder (MDD) affects millions of people worldwide and is a leading cause of disability. Several theories have been proposed to explain its pathological mechanisms, and the "neurotrophin hypothesis of depression" involves one of the most relevant pathways. Brain-derived neurotrophic factor (BDNF) is an important neurotrophin, and it has been extensively investigated in ...
Neurotrophic Factors: An Overview
The neurotrophic hypothesis gained momentum following isolation of a second neurotrophic factor, designated brain-derived neurotrophic factor (BDNF ) [].Molecular cloning of the BDNF gene [] revealed its structural similarity to NGF , leading to the concept of the neurotrophin family.. Later studies led to the identification of two additional members of this family, namely, neurotrophin-3 (NT ...

THE NEUROTROPHIC HYPOTHESIS OF DEPRESSION. Several studies have led to the formulation of the Neurotrophic Hypothesis of Depression, which postulates that low levels of brain-derived neurotrophic factor (BDNF) lead to a depression condition [19, 20].Neurotrophins are growth factors with crucial roles in the formation and plasticity of neuronal networks [].

Its principal tenet developing neurons depends on the supply of a neurotrophic factor that is synthesized in their target fields.

Neurotrophic factors
Neurotrophic factors (NTFs) are a family of biomolecules - nearly all of which are peptides or small proteins - that support the growth, survival, and differentiation of both developing and mature neurons. Most NTFs exert their trophic effects on neurons by signaling through tyrosine kinases, usually a receptor tyrosine kinase.In the mature nervous system, they promote neuronal survival ...

Brain-derived neurotrophic factor
Brain-derived neurotrophic factor (BDNF), or abrineurin, is a protein that, in humans, is encoded by the BDNF gene. BDNF is a member of the neurotrophin family of growth factors, which are related to the canonical nerve growth factor (NGF), a family which also includes NT-3 and NT-4/NT-5. Neurotrophic factors are found in the brain and the periphery. BDNF was first isolated from a pig brain in ...
