TrkB (Tropomyosin receptor kinase B)

TrkB, or Tropomyosin receptor kinase B, is a protein that plays a crucial role in the nervous system. It acts as a receptor that binds to a growth factor called BDNF (brain-derived neurotrophic factor), which supports the survival, growth, and maintenance of neurons (brain cells). This interaction helps promote brain health, learning, and memory. Abnormalities in TrkB signaling have been linked to various neurological disorders, highlighting its importance in brain function and overall mental well-being. Understanding TrkB could lead to new treatments for conditions like depression and neurodegenerative diseases.
