Neurodegeneration is known as a neurological disorder that comes with developing atrophy and irreversible damage of neurons. Two of the most common neurodegenerative diseases are Parkinson’s (PD) and Alzheimer’s (AD).

The growth factors that are responsible for the survival, maintenance, and regeneration of specific neurons are NGF, GDNF, and BDNF. Such growth factors make them therapeutics for neurodegenerative diseases.

Clinical trials of NGF (therapeutic choice for AD), GDNF (treatment for PD), and BDNF (therapeutic target for both AD and PD) are ongoing.

Furthermore, therapies targeting neurotrophic factors and related receptors can also be a successful method for the less common neurodegenerative diseases like amyotrophic lateral sclerosis (ALS), Huntington’s (HD), and Rett Syndrome.

Neurotrophins and Receptors

Neurotrophins are known as growth factors crucial for neuron development, maintenance, and survival. Four neurotrophin family members are available: BDNF, NGF, neurotrophin 3, and neurotrophin 4.

They have the potential to bind to particular Trk receptors with high affinity and p75NTR with low affinity. This is done to evoke neurotrophic or pro-apoptotic signaling. NGF binds to TrkA; BDNF and neurotrophin 4 bind to TrkB; neurotrophin 3 binds to TrkC. BDNF, NGF, and all the receptors are known as targets for therapy in AD. Also, for PD, BDNF is a therapeutic choice.

NGF (Nerve growth factor)

In the neurotrophin family, NGF is known to be the first discovered member. It is crucial in the survival, growth, and maintenance of particular kinds of neurons.
