Frequently Asked Questions

What does NGF stand for?

Nerve growth factor. It is one of a family of proteins called neurotrophins, which support the survival and growth of nerve cells.

What is the difference between NGF and BDNF?

Both are neurotrophins, but they act on different populations of neurons. NGF mainly supports sensory and sympathetic neurons in the peripheral nervous system, while BDNF (brain-derived neurotrophic factor) acts more widely in the brain and is associated with learning and memory.

Is NGF linked to pain?

Yes. NGF sensitises pain-carrying nerve fibres, and drugs that block it have been trialled as painkillers for conditions such as osteoarthritis.
